Suppose a crew at an unloading dock can unload 3 trucks per hour and have already unloaded 17 trucks. Which equation can be used to model the number of trucks the crew unloads after h hours?
A. y = 3h = 17
B. y = 3h + 17
C. y = 17h – 3
<u>D. y = 17h + 3</u>

Answer:
- 75 and - 28
Step-by-step explanation:
To evaluate f(6) substitute x = 6 into f(x)
f(6) = - 2(6)² - 3 = - 2(36) - 3 = - 72 - 3 = - 75
Similarly
g(5) = - 5(5) - 3 = - 25 - 3 = - 28
5^?=625^x, x=1/4
To rewrite in exponential form, the equation would be 5^?=625^x. From here, the bases need to be set equal. Since the fourth root of 625 is 5, the new equation becomes 625^1/4=625^x (625^1/4 is the same as the fourth root of 624). Now that the bases are the same, you can just solve for the variables, which become 1/4=x. Hope this helps :)
