Answer:
Step-by-step explanation:
a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.
Table for the corresponding points will be,
x w(x) r(x)
0 0 0×4 = 0
15 60 60×4 = 240
30 120 120×4 = 480
45 180 180×4 = 720
b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).
c). Since, w(x) = 4x
and r(x) = 4[w(x)]
r(x) = 4(4x) = 16x
r(x) = 16x

Answer:
12
Step-by-step explanation:
zeros are the x-intercepts of any function. to find the x-intercept of this given function, we have to set y equal to 0.
0= -1/2x+6
-6=-1/2x
12=x
x=12
the x-intercept is (12,0), meaning 12 is the zero of this function.

4104 total votes, how many yes votes were there?
Answer:
the residents of a city voted on whether to raise property taxes. The ratio of yes to no votes was 5 to 8. If there were 6776 no votes, what was the total number of votes?
-------
5 to 8 is the same as 5x to 8x where 8x is the number of no votes.
----
If 8x = 6776, then x = 847

You begin painting your house with 10 gallons of paint you purchased at the hardware store. Each gallon of paint covers 400
square feet of surface area. If g is the gallons of paint used for painting x square feet, which type of model would best describe the
relationship between g and x?
A)
linear
B)
radical
quadratic
D)
exponential
Answer:
A) linear
Step-by-step explanation:
Let the gallons of paint be represented by g, and the area by x.
Each gallon of paint covers 400 square feet of surface area.
⇒ x = 400g
So that; when g = 1,
x = 400 square feet
when g = 5,
x = 400 x 5
= 2000 square feet
when g = 10,
x = 400 x 10
= 4000 square feet
The relationship between the variables is linear because g and x increases at a constant rate.

Line j passes through points (10, 10) and (1, 3). Line k is parallel to line j. What is the slope of line k?
Answer:
= (10-3) ÷ (10-1) = 7 ÷9 = 7/9
Step-by-step explanation:
As they are parallel, their slopes are the same. So if we find slope of line j we find slope of line k when we have two points of one line like (x1 , y1) and (x2 , y2) the slope of that line is (y2-y1) ÷ (x2-x1)

Answer:
y = 15∠abc = 68°∠bac = 78°∠acb = 34°Step-by-step explanation:
It is helpful to realize that the exterior angle is equal to the sum of the remote interior angles:
146° = (5y+3)° +(4y+8)°
135 = 9y . . . . . . . . . . . . . . divide by °, subtract 11
15 = y . . . . . . . . . divide by 9
∠abc = (4y+8)° = (4·15 +8)° = 68°
∠bac = (5y+3)° = (5·15 +3)° = 78°
∠acb = 180° -146° = 34°

3/4 (6x + 1) - 3x = 1/4 (2x - 1)
3/4 (6x + 1) - 3x = 1/4 (2x - 1) . The purpose of this question is to solve for x.
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]
Given that:
3/4 (6x + 1) - 3x = 1/4 (2x - 1)When calculating algebraic expression, we take note of integers in bracket first, then we collect the like terms in order to find the value of x.
[tex]\mathbf{\dfrac{3}{4} (6x + 1) - 3x =\dfrac{1}{4} (2x - 1) }[/tex]
Let's multiply both sides by 4 to eliminate the fraction.
[tex]\mathbf{(\dfrac{3}{4} \times 4) (6x + 1) - 3x =(\dfrac{1}{4} \times 4 ) (2x - 1) }[/tex]
[tex]\mathbf{(3) (6x + 1) - 3x =(1 ) (2x - 1) }[/tex]
Open brackets;18x + 3 - 3x = 2x - 1
By rearrangement;18x - 3x + 3 = 2x - 1
15x + 3 = 2x - 1
Collect like terms15x - 2x = - 3 - 1
13x = - 4
Divide both sides by 13[tex]\mathbf{\dfrac{13x}{13} = \dfrac{-4}{13}}[/tex]
[tex]\mathbf{x = \dfrac{-4}{13}}[/tex]

A plumber earns $50 for a repair job, plus an additional $75 per hour he works. On Tuesday, he completed 3 repair jobs and earned a total of more than $600. Part A: Write an inequality that can be used to determine h, the number of hours the plumber worked Tuesday.
Answer:
[tex]150 + 75h > 600[/tex]
Step-by-step explanation:
The inequality that can be used to determine h is shown below:-
As per the given situation, it is mentioned that a plumber could earns $50 for a repair job, so for three jobs he earned $150 as a total amount
Now
We presume h be the number of hours
Also he earns additional $75 per hour worked so $75
Total amount is $150 + $75h)
The total amount is more than $600
So, the inequality equation is as given below:
[tex]150 + 75h > 600[/tex]
