If you draw out a coordinate plane you will see that they , on their Y access, are both nine witch means that they a horizontal line so all you have to do is subtract the x access witch is 3.
hope this helped

Answer:
c = 420t . . . . c is calories burned; t is hours riding at 15 mph
Step-by-step explanation:
There is not enough information given to write a function rule relating all the variables to calories burned. If we assume that calories are burned at the constant rate of 420 calories per hour, then total calories will be that rate multiplied by hours:
c = 420·t
where c is total calories burned by the 154-lb person, and t is hours riding at 15 mph.
___
In general, rates are related to quantities by ...
quantity = rate · time . . . . . where the rate is (quantity)/(time period)
Answer:
B.
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define function</u>
f(x) = 8x + 4
<u>Step 2: Prep</u>
- Rewrite: y = 8x + 4
- Swap <em>x</em> and <em>y</em>: x = 8y + 4
<u>Step 3: Find Inverse (Solve for </u><em><u>y</u></em><u>)</u>
- Subtract 4 on both sides: x - 4 = 8y
- Divide both sides by 8: (x - 4)/8 = y
- Rewrite: y = (x - 4)/8
- Rewrite: f⁻¹(x) = (x - 4)/8
