The descent after 16 seconds would be 672 feet, with the function -42•X and X=16 so -42•16=-672
Answer:
98
Step-by-step explanation:
So we have the expression:

And we want to evaluate it when x is 3 and y is 8.
So, substitute:

Multiply:

Add:

And we're done!
Answer:
10.34%
Step-by-step explanation:
29×x%=3
X=10.34%
Answer:
(i think) 1.5
Step-by-step explanation:
If you replace y with the equation y=2x-3, you get 5(2x - 3)
if you distribute this, it equals 10x - 15
combining like terms 10x + 10x - 15=15 will turn into 20x - 15 = 15
if you add 15 to both sides, -15 will cancel and 15 will turn into 30
20x = 30
divide both sides by 20 which will lead to x=1.5
I want to say the third option but dont trust my opinion
