Answer:
7 and 8: these are both proportional relationships because they grow at a constant rate of change
9: for every 40 miles that the car travels, it uses 2 gallons of gas.
10: y= 20x
11: the graph would be steeper and have a greater rate of change. This car would be able to go farther on less fuel.

Describe the transformation that takes f(x) = x+1 to g(x) = -x+4.
Answers
Answer:
Reflecting over the x-axis, vertical movement up 3 units.
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptTransformations of graphs
Step-by-step explanation:
Step 1: Define
f(x) = x + 1
g(x) = -x + 4
Step 2: Define
Multiplying -1 to x flips it over the x-axis, or known as a reflection. There is no vertical shrink/stretch.
To get to 1 to 4, we add 3. That means we will be moving the graph up 3 units.
Answer:
The sign on the 'x' changes, this implies a reflection.
g(x) = -f(x) = -(x+1) = -x -1
Now apply a vertical translation 'up 5' to f(x)
g(x) = -f(x) + 5 = (-x-1) +5 = -x +4

three numbers have a sum of 112. The first number is twice the second, and the third number is twice the first. What is the smallest of the three numbers?
Answers
Answer:
The second number is the smallest of the three numbers with
value n = 16.
Step-by-step explanation:
Let n represent the second number, then the first number is 2n and the third number is 4n.
so
[tex]n+2n+4n=112[/tex]
Solving for n
[tex]n+2n+4n=112[/tex]
[tex]7n=112[/tex]
[tex]\frac{7n}{7}=\frac{112}{7}[/tex]
[tex]n=16[/tex]
As n = 16 is the second number.
The first number = 2n = 2(16) = 32
The third number = 4n = 4(16) = 64
Therefore, the second number is the smallest of the three numbers with value n = 16.

What is the measure of
angle b?
Answer: 36
Answers
okay so
117° + angle a = 180° (supplementary angle)
angle a = 180 - 117
= 63°
then angle a + angle b + 81° = 180° ( angle sum property)
so... 63° + angle b + 81° = 180
144 + angle b = 180°
angle b = 180 - 144
= 36°

In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11.
sin42∘≈0.67
cos42∘≈0.74
tan42∘≈0.90
What is the measurement of HI?
If necessary, round your answer to two decimal places, like this: 42.53
Answers
Answer:
12.22
Step-by-step explanation:
θ = 42°
We solve using Tangent rule of trigonometry.
tan θ = Opposite/Adjacent
GH = Opposite = 11
HI = Adjacent = ?
From the question
tan42∘≈0.90
Hence:
0.90 = 11/HI
HI = 11/0.90
HI = 12.222222222
Approximately = 12.22
