Answer:
If you substitute (-1,2) meaning x and y
2=3(-1)-2
2=-3-2
2= -1
Step-by-step explanation:
he's incorrect since the solution does not equal 2 on both sides
Answer:
y
Step-by-step explanation:
First you would find y because two or more of the numbers have it. Then you would be able to solve for x
-6 = y/5 + 4
Step 1: Subtract 4 from each side of the equation.
Step 2: Multiply each side by 5.
If you don't arrive at the solution y= -50 , then return to Step-1
and repeat the process, being on the lookout for your mistake.
I think you got to multiply the numbers hopefully I helped
Answer:
The time that the rocket will hit the ground is 12.87 seconds.
Step-by-step explanation:
Given : The rocket is launched from a tower 
. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.
To find : The time that the rocket will hit the ground ?
Solution :
When the rocket hit the ground i.e. height became zero y=0,
Equation is
Substitute y=0,
Using quadratic formula, 
Reject negative value.
The time taken is 12.87 seconds.
