Answer:
The inequality describes all possible value of x is 14 < x < 32 ⇒ D
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesIn the given figure
∵ ABC is a triangle
∵ AC = 9 and BC = 21
∵ AB is the third side of the triangle
→ By using the rules above
∴ BC - AC < AB < BC + AC
∵ AB = x - 2
→ Substitute their values in the inequality above
∵ 21 - 9 < x - 2 < 21 + 9
∴ 12 < x - 2 < 30
→ Add 2 to the 3 terms
∴ 12 + 2 < x - 2 + 2 < 30 + 2
∴ 14 < x < 32
∴ The inequality describes all possible value of x is 14 < x < 32

Is x=|y| with inputs x=1, x=2, and x=3 a function? Explain
Answers
Answer: This is not a function
======================================================
Explanation:
If x = 1, then,
x = |y|
1 = |y|
|y| = 1
y = plus/minus 1
y = 1 or y = -1
The input x = 1 leads to more than one output y = 1 and y = -1 at the same time.
Similar situations occur with x = 2 and x = 3.
This means we do not have a function. A function can only be possible if each input leads to exactly one output.
The sum of four consecutive odd integers is –72. Write an equation to model this situation, and find the values of the four integers.
A.
n + n + 2 + n + 4 + n + 6 = –72; n = –21; n + 2 = –23; n + 4 = –25; n + 6 = –27
B.
n + (n – 2) + (n – 4) + (n – 6) = –72; n = – 21; n – 2 = –23; n – 4 = –25; n – 6 = – 27
C.
n – (n + 2) – (n + 4) – (n + 6) = –72; n = –20; n + 2 = –18; n + 4 = –16; n + 6 = –14
D.
n + n + 2 + n + 4 + n + 6 = –72; n = –21; n + 2 = –19; n + 4 = –17; n + 6 = –15
Answers
Answer:
D. n+n+2+n+4+6= -72; n= -21; n+2= -19; n+4= -17; n+6= -15
There are 2 below and 2 above it.
-15, -17, -19, -21
Step-by-step explanation:
the sum of four consecutive odd integers is -72. write an equation to model this situation, and find the values of the four integers .
n + n+2 + n+4 + n+6 = -72
4n + 12 = -72

Solve the area formula for a circle, A = πr2, for r2.
r2 = Aπ
r2 = A – π
Answers
Answer:
The solution of r² is r² = [tex]\frac{A}{\pi }[/tex]
Step-by-step explanation:
To solve an equation for one of its variables, do that
Separate the term of this variable on one side and the other terms on the other sidesMake the coefficient of the variable equals1 (if it is not 1)Let us solve the question
∵ The formula of the area of the circle is A = π r²
∵ The subject is r² ⇒ The variable which we need to solve for it
→ By using the 1st step up divide both sides by π to move it from the right
side to the left side
∵ [tex]\frac{A}{\pi }[/tex] = [tex]\frac{\pi r^{2}}{\pi }[/tex]
∴ [tex]\frac{A}{\pi }[/tex] = r²
→ Switch the two sides
∴ r² = [tex]\frac{A}{\pi }[/tex]
Write the equation of the line that passes through the point (1,4) and is parallel to y=5
Answers
Answer:
The equation of the desired line is thus y = 4
Step-by-step explanation:
A line parallel to y = 5 is a horizontal line. The x-coordinate of every point on this line can take on any x-value; the y-coordinate is always 5.
The line that passes through the point (1, 4) has the constant y-coordinate 4, whereas x can take on any value.
The equation of the desired line is thus y = 4; this line passes through (1, 4) as required and is parallel to y = 5.
Jacy paid $15.48 to download 12 songs last month. She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.
Part A
Let s represent the amount that Jacy paid for each song she downloaded.
Which equation could you use to find the value of s?
12s = 15.48
15.48 + s = 12 + 5.04
12 + s = 15.48 + 5.04
12s + 5.04 = 15.48

given that,
Jacy paid $15.48 to download 12 songs last month.
She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.
now, we have,
Let s represent the amount that Jacy paid for each song she downloaded.
so, we get,
She paid the same amount for each song and also had to spend $5.04 to enroll in the music purchasing program.
i.e. 12s + 5.04
and, Jacy paid $15.48
i.e. the equation which could you use to find the value of s is,
12s + 5.04 = 15.48
Hence, The solution is, 12s + 5.04 = 15.48, is the equation which could you use to find the value of s.

Divide £320 in the ratio 3:5
Answers
Answer:
£120 : £200
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 = 8 parts
Divide the amount by 8 to find the value of one part
£320 ÷ 8 = £40 , then
3 parts = 3 × £40 = £120
5 parts = 5 × £40 = £200
Then £320 in the ratio 3 : 5 is £120 : £200
The division of £320 in the ratio of 3: 5 is £120: £200.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given the amount of £320
Now,
The ratio is 3: 5 so divide 320 by 3 + 5 to find the per unit ratio value.
So,
320/8 = 40
Now,
Multiply by 3 ⇒ 3 × 40 = 120
Multiply by 5 ⇒ 5 × 40 = 200
So ratio 120/200 = £120: £200.
Hence "The division of £320 in the ratio of 3: 5 is £120: £200".

What is the solution to the equation 4 ( b − 2 ) − 10 = 2b + 6 ?
Answers
Step by step explanation:
First simplify both sides of the equation
( 4 )( b ) + ( 4 ) ( - 2 ) + -10 = 2b + 6 (distribute)
4b + -8 + -10 = 2b + 6
(4b) + (-8 + -10 ) = 2b + 6 (combine like terms)
4b + -18 = 2b + 6
4b - 18 = 2b + 6
Then subtract 2b from both sides
4b - 18 - 2b = 2b + 6 - 2b
2b - 18 = 6
After that you add 18 to both sides
2b - 18 + 18 = 6 + 18
2b = 24
2b/2 = 24/2
b = 12

Unfortunately, Fred had some trouble in the kitchen and 3/5 of the peanut butter cookies were burned. a. How many peanut butter cookies does Fred have left to sell?
Answers
Answer: 12 peanut butter cookies
Step-by-step explanation:
Fred had made 10 dozen cookies which means he made:
= 10 * 12
= 120 cookies
Out of those, 1/4 were peanut butter:
= 120 * 1/4
= 30 peanut butter cookies
He burned 3/5 of the peanut butter cookies:
= 30 * 3/5
= 18 cookies were burnt
The amount let is therefore:
= 30 - 18
= 12 peanut butter cookies
Point M is on line segment LN. Given MN = 3x, LN = 4x + 9, and
LM 2x + 7, determine the numerical length of LM.
Answers
Answer:
LM = 11 units
Step-by-step explanation:
Given M is on LN , then
LM + MN = LN , substitute values
2x + 7 + 3x = 4x + 9
5x + 7 = 4x + 9 ( subtract 4x from both sides )
x + 7 = 9 ( subtract 7 from both sides )
x = 2
Thus
LM = 2x + 7 = 2(2) + 7 = 4 + 7 = 11

How would the intervals of the solution set differ between a polynomial inequality and a rational inequality?
Answers
Answer:
Two differences: A polynomial inequality (PI) can always be replaced by a PI with one side zero. A rational inequality (RI) can not, because you do not know the sign of the denominator; a(x)b(x)>c(x)d(x) can not safely be replaced by a(x)d(x)−b(x)c(x)b(x)d(x)>0 because b(x) and/or d(x) might change signs unexpectedly.

Write the equation for the line with the given points (0,-3) and (2,9) in point slope form

First of all, we will solve for our M which is our slope.
M = Yb - Ya / Xb - Xa
M = 9 - (-3) / 2 - 0
M = 9 + 3 / 2 - 0
M = 12 / 2
M = 6
Now that we have our slope, we will be finding our y-intercept.
Y = mx + b
9 = (6)(2) + b
9 = 12 + b
= 9-12 = 12-12 + b (12 cancels out)
= -3 = b
So, therefore, the equation is: Y = 6x - 3

Jayden drew a scale drawing of an arcade. He used the scale 1 inch = 3 feet. If an air hockey table is 3 inches long in the drawing, how long is the actual air hockey table?
Answers
Answer:
9 Feet
Step-by-step explanation:
Lets start with a ratio:
1:3
Now lets look at the other ratio:
3:?
If the 1 turned into a three in the second ratio, then what will the 3 in the first ratio turn into?
9!
Because 1x=3 should be equivalent to 3x=9
Lets check our work:
x=3
3x=9
Simplify by dividing by 3 on both sides:
x=3
x=3
It worked!
The answer is 9 feet. If the air hockey table is 3 inches long and 1 inch = 3 feet, 3 x 3 = 9.
