Answer:
y = 5 + 7x
Step-by-step explanation:
So 5 is going to be a constant factor. So Y is gonna equal 5 plus something. 12 dollars for every hour is 12x and there is a 5 dollar discount. 12-5 = 7 and so it is 7 dollars per hour.
So the total cost Y equal the constant 5 and 7x
Y = 5 + 7x
please answer the two question and how you answered it NO LINKS AND NO WEBSITES I really need help with tthis, and also if it's Substitution or linear combination.
Answer:
(x, y) = (6, 8) using linear combination
Step-by-step explanation:
The coefficients of the x-terms are opposites of each other (2 and -2), so the x-terms can be eliminated using a linear combination of the equations.
Adding the two equations together gives ...
(2x -y) +(-2x +3y) = (4) +(12)
2y = 16 . . . . . . . . simplify
y = 8 . . . . . . . divide by 2
Substituting for y in the first equation gives ...
2x -8 = 4
x -4 = 2 . . . . . divide by 2
x = 6 . . . . . . . add 4
The solution is (x, y) = (6, 8).

Answer: x = 0.79128784 and -3.79128784
Step-by-step explanation: Round them up
Factorizing an expression involves writing the expression in simpler forms
The expression cannot be factorized.
The expression is given as:
[tex]0 = x^2 + 3x - 3[/tex]
Rewrite the expression as:
[tex]x^2 + 3x - 3 = 0[/tex]
The above expression cannot be factorized.
This is so because 3x can not be expressed using terms that have the product of -3 and x^2

What is simplification?Simplification is defined as a process in mathematics to operate and interpret an expression to make the expression simpler.
This can be done using various results or the basic operations of numbers.
Given expression is 3⁻⁶ × (3⁴ / 3⁰)².
We have to use product rule and quotient rule of exponents to simplify this.
We know that,
xᵃ × xᵇ = xᵃ⁺ᵇ
xᵃ / xᵇ = xᵃ⁻ᵇ
Also, (xᵃ)ᵇ = xᵃᵇ
3⁴ / 3⁰ = 3⁴⁻⁰ = 3⁴
Substituting,
3⁻⁶ × (3⁴ / 3⁰)² = 3⁻⁶ × (3⁴)²
= 3⁻⁶ × 3⁸
= 3⁻⁶⁺⁸
= 3²
= 9
Hence the simplified form of the given expression is 9.

Answer:
7.07
Step-by-step explanation:
Angle M is 63 degrees because all 3 angles must add to 180.
Now use the law of sines:
sin(90)/x = sin(63)/6.3
Cross multiply: 6.3 sin (90) = x sin (63)
Divide by sides by sin (63): (6.3 sin (90))/sin (63) = x

Wilson Green sells home security systems. He earns an 13% commission on every system he sells. Wilson's sales for this month totaled $6425. What is Wilson's commission? *
Answer
$835,25
Explanation
Total sales = $6425
Commission = 13%
100% - $6425
13% - x
13 * 6425 = 83525
83525 \ 100 = 835,25
write an equation in slope intercept form of the line that passes through the points (-3,6) and (0,0)
Answer:
y=-2x
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-6)/(0-(-3))
m=-6/(0+3)
m=-6/3
m=-2
y-y1=m(x-x1)
y-6=-2(x-(-3))
y-6=-2(x+3)
y=-2x-6+6
y=-2x
Note that the slope-intercept form is y=mx+b where m=slope and b=y-intercept.

The value of x from the given equation is [tex]19\frac{2}{3}[/tex].
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The given equation is 213-12x=-23.
Now, 213+23=12x
⇒ 12x=236
⇒ x=236/12
⇒ x=59/3
⇒ x=[tex]19\frac{2}{3}[/tex]

3. The endpoints will have the same letters.
4. They are congruent.
A copy of a line segment will have the same measure or length as the segment.
The true statement is (4) They are congruent.
From the question, we understand that a copy of the line segment is created.
This means that the new segment has the exact property as the original line segment.

Answer:
< 1 is 85
X= 50
Step-by-step explanation:
ok the first question has 2 angles given 60 and 65
consider this one shows a 90 degree angle and the other does not. so 60 plus 90 equals 150 degrees
the u must say 65 plus x (x being angle 1) must also equal 150
subtract 65 from 150 and you get 85
now the second problem lets use the
Exterior Angle Theorem
The measure of an exterior angle (our w) of a triangle equals to the sum of the measures of the two remote interior angles (our x and y) of the triangle.
using this we know the 40 degree angle and 2x + 20 equals 3x plus 10
so we subtract 10 degrees from both sides and get
2x plus 10 plus 40 equals 3x now this means x equals 10 plus 40 which is 50
