Answer:
C. h + k (t - 1)
Step-by-step explanation:
<em>If we use an example, you can plug in the numbers and test out which equation works. Say the first hours costs $10 and each hour after that is an additional $5. If someone rents a jet ski for 4 hours, how much did it cost?</em>
The first hour = $10
The 3 additional hours (totaled) = $15
Cost = $25
<em />
<em>So now that we know the cost, we can plug in our numbers to these equations to find which one comes out with $25.</em>
h = 10
k = 5
t = 4
<u>A</u>. 10 + 4 + 5 = <u>19</u>
<u>B</u>. 10 + (4 · 5) = 10 + 20 = <u>30</u>
<u>C</u>. 10 + 5 (4 - 1) = 10 + 5 (3) = 10 + 15 = <u>25</u>
<u>D</u>. 10 + 5 (4 + 1) = 10 + 5 (5) = 10 + 25 = <u>35</u>
<u>E</u>. 10 + (4/5 - 1) = 10 + (-0.2) = <u>9.8</u>
<em>C is the only problem that comes out as $25, therefore it must be the correct answer.</em>
Answer:
y = (5/2)x + 4
Step-by-step explanation:
We'll look for an equation in the format y = mx + b, where mn is the slope and b the y-intercept (the value of y when x = 0).
y = mx + b
m is (5/2)
y = (5/2)x + b
We need a value of b that will force the line through point (-2,-1). Enter the point (-2,-1) in the equation and solve for b:
y = (5/2)x + b
-1 = (5/2)(-2) + b
-1 = -5 + b
b = 4
<u>The equation is y = (5/2)x + 4</u>
