I’m also struggling with the exact same type of problem too bad no one is willing to help me :((
Answer:
(4, 1 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 11 → (1)
x - 3y = 1 → (2)
Adding (1) and (2) term by term will eliminate the term in y
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and evaluate for y
Substituting into (1)
2(4) + 3y = 11
8 + 3y = 11 ( subtract 8 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
Solution is (4, 1 )
Answer:
35+2
Step-by-step explanation:

When rocket hit the ground the height of rocket from the ground is 0. So y = 0, when rocket hit the ground.
Simplify the equation -16x^2+248x+116 = 0 by using quadratic formula to obtain the value ot time, x.
The negative value of time is neglected as time can never be negative.
Thus time at which rocket hit the ground is 15.95 seconds.
Answer:
No
Step-by-step explanation:
The exponents are too far apart for a +2 to make a difference.
