find y=mx+b for line parallel to AB.
The line that is parallel will have the same slope as line AB:
the slope of line AB is
m=(8-3)/(-10-2)
=5/-12
=-5/12
Since the line going through X is parallel the vertical distance of the new line to AB is the same for all values of the domain(x-axis).
at x=-5 the point X has the y value of 10 which is 4 more than the y value for AB based on the graph.
To find the intercept b of the line going through X that is parallel to AB we just add 4 to the intercept of AB, which is 4 so
4+4=8

A parallelogram has adjacent sides 25 cm and 6 cm . if one diagonal is 29 cm then find area , height corresponding to the sides 25 cm and perimeter.
very important question.....
plz do fast.
Answers
Answer:
height = 4.8 cm
area = 120 cm²
perimeter = 62 cm
Step-by-step explanation:
**Please refer to the attached diagram when following the step-by-step**
First, find m∠C (green angle on diagram) by using the cosine rule:
[tex]c^2=a^2+b^2-2abcos(C)[/tex]
[tex]\implies 29^2=6^2+25^2-2(6)(25)cos(C)[/tex]
[tex]\implies cos(C)= \frac{29^2-6^2-25^2}{-2(6)(25)}[/tex]
[tex]\implies cos(C)= \frac{180}{-300}=-\frac{3}{5}[/tex]
[tex]\implies cos(C)=126.8698976... \textdegree[/tex]
Therefore, the interior angle of the right triangle at point C (blue angle on diagram) is:
[tex]180-cos^{-1}(-\frac{3}{5})=53.13010235... \textdegree[/tex]
Now use the Sine Rule (for finding sides) to determine height (h):
[tex]\frac{6}{sin(90)}=\frac{h}{sin(53.13..)}[/tex]
[tex]\implies \frac{6}{1}=\frac{h}{\frac{4}{5}}[/tex]
[tex]\implies 6 \times \frac{4}{5}=h[/tex]
[tex]\implies h=\frac{24}{5}=4.8[/tex]
So the height = 4.8 cm
Now we have determined the height, we can calculate the area by using the area of a parallelogram formula:
Area of a parallelogram = base x perpendicular height
⇒ area = 25 x 4.8 = 120 cm²
Parallelogram is a four-sided shape made up of two pairs of straight parallel lines that are equal in length.
Perimeter = sum of the sides
⇒ perimeter = 6 + 6 + 25 + 25 = 62 cm
Why is the domain of the square root parent function x ≥ 0 and the domain of the cube root parent function all real numbers?
Answers
Answer:
here may be more than one correct answer.
Cubic, f(x)=x^3
Quadratic, f(x)=x^2
Square root, f(x)=√x
Constant, f(x)=c
Linear, f(x)=x
Step-by-step explanation:
The domain of the square root parent function is x ≥ 0 as the square root of only non-negative values exists and that of negative values does not exist, while the domain of the cube root parent function is the set of all real numbers as the cube root of all numbers exists.
What is a function?A function is a relation between a dependent variable f(x) and an independent variable x, where for every value of x in its domain, there is one and only one value of f(x).
What is the domain of a function?The domain of a function is the set of values of x, for which f(x) exists.
What is the range of a function?The range of a function is the set of values of f(x), in a given domain of x.
How do we solve the given question?We are asked why is the domain of the square root parent function x ≥ 0 and the domain of the cube root parent function all real numbers.
We know that the domain of a function is the set of values of x, for which f(x) exists.
Let the square root parent function be f(x) = √x.
The domain of this function is x ≥ 0, as the square root of negative values does not exist in the real number system.
Let the cube root parent function be g(x) = ∛x.
The domain of this function is all real numbers, as the cube root of all values does exist in the real number system.
∴ The domain of the square root parent function is x ≥ 0 as the square root of only non-negative values exists and that of negative values does not exist, while the domain of the cube root parent function is the set of all real numbers as the cube root of all numbers exists.

How can you determine the number of solutions of a system by looking at the equationz
Answers
Answer:
Look at the variables and numbers in the equation, and what it equals
Step-by-step explanation:
Expressions that are the exact same have infinite solutions
[tex]5x+3=5x+3[/tex]
Expressions that are different have 1 solution
[tex]6x+7=5x-2[/tex]
Expressions that are the same with different operands have no solution
[tex]5x-3=5x+3[/tex]
Explanation:
The short of it is that when the equations are in the same form, if one equation is the same as or a multiple of the other, there are infinite solutions. If one equation is the same as or a multiple of the other, except for the constant terms, there are no solutions. Otherwise, there is one solution.
Example:
If one equation is x +2y = 3, then you can consider the other equation:
3x +6y = 9 . . . . 3 times the first equation: infinite solutions
3x +6y = 6 . . . . 3 times the first equation; constants differ: no solutions
3x -6y = 9 . . . . not a multiple of the first equation: one solution
_____
Here's a more formal method.
Put both equations of the linear system of two equations into general form:
ax +by +c = 0
dx +ey +g = 0
Perform the following arithmetic:
p = ae -db . . . . . this is called the system "determinant"
q = bg -ec
r = cd -ga
If p = q = r = 0, the equations describe the same line, so there are infinite solutions.
If p = 0 and either of q ≠ 0 or r ≠ 0, the equations describe parallel lines, so there are no solutions.
If p ≠ 0, there is one solution: (x, y) = (q/p, r/p).
_____
Additional comment
This method can always be used to find the solution to a system that is known to have one solution. It often requires fewer arithmetic operations than other solution methods. It is a variation of what is sometimes called the "cross multiplication method."
Find the average yearly salary of an architect and a lawyer. The average yearly salary of an architect is $____ thousand
Answers
Answer:
Let x = salary of the architect, in thousands
Let 2x - 25 = salary of a lawyer, in thousands
2x + 2x - 25 = 206 (combined salaries, in thousands)
4x - 24 = 206
4x = 206 - 25 = 181
x = 45.25, in thousands.
The architect earns $45,250 yearly
The lawyer earns $65,500 yearly
If you want to set up a system of equations with 2 variables.
Let x = the salary of the architect, in thousands.
Let y = the salary of the lawyer, in thousands.
x + y = 206
y = 2x - 25
Solving by substitution will yield the same equation as above: x = 45.25 or $45,250
Then y = 2(45,250) - 25,000 = $66,500
How do I solve this equation?
through: (-2, 4), slope = -7/-2
the formula is: y=mx+b
Answers
Answer:
[tex]y=\frac{7}{2}x+11[/tex]
Step-by-step explanation:
To solve, we need to find the y-intercept (b). In order to find the y-intercept, we can plug in the slope and the (x,y) coordinate pair given to us into the equation to solve for the y-intercept:
y=mx+b
4=(-7/-2)*-2+b
4=14/-2+b
4=-7+b
Add 7 to both sides
b=11
Therefore the equation is:
[tex]y=\frac{7}{2}x+11[/tex] (note that the fraction is positive since the two negatives cancel out)

Answer: 12 and 8
Step-by-step explanation:

The integer m whose factors are 15,12,10 and 6 is 60 and 8 is not, therefore, for integer 60, 8 will be not the factor so option (D) is correct.
What is an integer?An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.
Integer ; ....-2 , -1 , 0 , 1 , 2 , .....
Integers are non-decimal numbers and all integers are rational numbers.
The factors of 10 ⇒ 2 × 5
The factors of 12 ⇒ 2 × 2 × 3
The factors of 10 × 12 ⇒ 2 × 5 × 2 × 2 × 3
We can make all factors by 2 × 5 × 2 × 2 × 3 like 5 × 3 = 15 , 2 × 2 × 2 = 8.
So find a number whose all will be a factor except one.
The factor of 60 ⇒ 2 × 2 × 3 × 5
We cannot make 8 by this factor but can make 15,12,10,6.
Example 15 = 3 × 5 , 12 = 2 × 2 × 3
Hence "The integer m whose factors are 15,12,10 and 6 is 60 and 8 is not, therefore, for integer 60, 8 will be not the factor".

The senior class of Oakdale Christian School traveled 630 miles in one day on their trip to the Grand Canyon. After lunch, they traveled twice as far as they did before lunch. How many miles did they travel after lunch?
Answers
Answer:
420 miles after lunch
Step-by-step explanation:
Day 1 is 630 miles travelled - total amount of travelling.
After lunch is twice the amount of m.
Twice means 2.
So,
2xm + m (they'd have travelled) = 630 total miles
(2xm = 2m & 1m is the same as m)
2m + 1m = 630
3m = 630
÷3
m = 210 miles
Initial miles travelled before lunch was 210.
After lunch is double that amount.
Thus, 210 x 2 = 420 miles
Check:
210 + 420 = 630 miles.

Julian owns a small business selling bagels. He knows that in the last week 57 customers paid cash, 12 customers used a debit card, and 70 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a debit card as a fraction in simplest form.
Answers
Considering the definition of probability, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].
Definition of probabilityProbability is the greater or lesser chance that a given event will occur.
In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases.
[tex]P(A)=\frac{number of favorable events}{ total number of possible events}[/tex]
The probability of event A can only be a number between 0 and 1; although it can also be written as a percentage.
Probability that the next customer pay with a debit cardIn this case, you know:
Total number of customers = 57 +12 +70= 139 (total number of possible cases)The number of customers that used a debit card = 12 (number of favorable cases)Replacing in the definition of probability:
[tex]P(A)=\frac{12}{ 139}[/tex]
Finally, the probability that the next customer will pay with a debit card is [tex]\frac{12}{139}[/tex].

<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
