Answer:

$4(11-y)^{2} -3y^{2}=8$

Step-by-step explanation:

we have

$x+y=11$ ----> equation A

$4x^{2} -3y^{2}=8$ ----> equation B

Solve the system by substitution

step 1

isolate the variable x in the equation A

$x=11-y$ ----> equation A1

step 2

Substitute the equation A1 in the equation B

$4(11-y)^{2} -3y^{2}=8$

Ray Of Light [21]

Answer:

x = -7

Step-by-step explanation:

5x+8=3x-6

Subtract 3x from each side

5x-3x+8=3x-3x-6

2x+8 = -6

Subtract 8 from each side

2x+8-8 = -6-8

2x = -14

Law Incorporation [45]

Given

$h=P(t)=-16t^2+1450$

Evaluate P(5), as shown below

$\begin{gathered} P(5)=-16*5^2+1450 \\ \Rightarrow P(5)=-400+1450=1050 \end{gathered}$

Therefore, the answer is 1050ft.
