Answer:
y = 4
Step-by-step explanation:
5x + y = -1
y = -1 - 5x
y = 6x + 10
6x + 10 = -1 - 5x
11x = -11
x = -1
y = 6x + 10 = 6(-1) + 10 = -6 + 10 = 4
Answer:
15 3/4t^2 + 5 1/4
Explanation:
h(t)=-16t^2+400
We can add 400 then - 64 and show as 8^2
= h(t)=-16t^2+400 - 8^2
But we also need to change 16t^2;
We divide 64 into 16 = 16/64 =0.25
and show 16t^2 changes by 0.25 = 1/4
15 3/4t^2 + 400-64
Can now look like
15 3/4t^2 + 5 1/4
As 5 1/4 = 64 x 5 1/4 = 336
Answer:
Step-by-step explanation:
8x + 12 = 3x + 5x + 12
8x + 12 = 8x + 12
Bringing like terms on one side
8x - 8x = 12 - 12
x = 0
The two long sides are 63meters and the shorter sides are 21meters.
