____________________________________________________

Solve for y:

5y-3(2-y)=10​

Distribute the -3 to the variables inside the parenthesis.

5y - 6 + 3y = 10

8y - 6 = 10

Add 6 to both sides

8y = 16

Divide both sides by 8

y = 2

HELP PLEASE

Answer: x^2=8y


Step-by-step explanation:

Let the given parabolic mirror opens upwards and vertex=(0,0)

Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror.  ∴ p=2

Since, the parabola opens upward, then the equation of the parabola is of the form x^2=4py

Substitute the value of p=2 in this, we get the equation of the parabolic mirror

x^2=4(2)y\\\Rightarrow\ x^2=8y

Hence, the equation of the parabola that models the cross section of the mirror is x^2=8y
