Answer:
Proportional
General Formulas and Concepts:
<u>Algebra I</u>
Any linear line is proportional
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define function</u>
y = 8.6x + 1.3
<u>Step 2: Identify</u>
The given function is a linear equation. It will be proportional
<u>Step 3: Graph</u>
<em>We can see that the x and y is proportional.</em>
Answer:
y=5
19y-15y=20
4y=20
Divide by 4 on each side
y=5
If you spent 1/2 at the theater, and 1/4 at the arcade then you spent 3/4 of your money leaving you with 1/4 left. multiply the amount of money you have left ($17.50), by 4. You originally had $70. hope this helps!
Answer:

Step-by-step explanation:
To find the inverse of a function, simply switch the 'x' and 'y' variables. Substitute in 'y' in the place of f(x) for this purpose:
y = 2x - 10
Switch positions:
x = 2y - 10
Add '10' to both sides to begin simplifying:
x + 10 = 2y
Divide both sides by 2:

This can be rewritten as:

Therefore, the inverse of the function is:

Answer:
(-1, -1)
Step-by-step explanation:
Assuming the dilation is centered at the origin, we can multiply each of the coordinates by the scale factor.
This gives A'(-1, -1)
