I think you have a problem with your equation. You can't have 2 equal signs. I would say 1200 is your slope though. I simply subtracted 20x from 1220x <span />
-4g + 12 = 16 then -12 on the both side
-4g = 4 then divided by -4, you will get g = -1
First off, you need to rewrite the equation as 3*2*3
Then you multiply 3 by 2 to get 6.
Then you multiply 6 by 3 to get 18.
Then the answer is 18.
Hope this helps :)
Assuming the numbers are exponents expect the coefficient of 2, top expression, -12x^3y^6, multiply bottom
and= 72x^4y^8
Answer:
They are at the same height at 1.13 seconds.
Step-by-step explanation:
Remark
The rockets are at the same height when f(x) = g(x) [see below] are the same. So you can equate them.
Givens
f(x) = - 16x^2 + 74x + 9
g(x) = -16x^2 + 82x I have changed this so you don't have 2 f(x)s
Solution
- f(x) = g(x)
- -16x^2 + 74x + 9 = -16x^2 + 82x Add: 16x^2 to both sides
- -16x^2+16x^2+74x + 9 = -16x^2+16x^2 + 82x Combine terms
- 74x + 9 = 82x Subtract 74x from both sides
- 74x - 74x + 9 = 82x - 74x Combine
- 9 = 8x Divide by 8
- 9/8 = 8x/8
- x = 1 1/8 Convert to decimal
- x = 1.125
- x = 1.13 [rounded]
