Your equations are correct.

Your equations are right. just use the substitution method to solve. substitute y because both have that on one side

it'll look like 40x+30=30x+60.
then just get x in one side. I showed my owrk in the photo

Factor and find all the roots of x^4 +x=0
Furkat [3]
         x⁴ + x = 0
x(x³) + x(1) = 0
    x(x³ + 1) = 0
x = 0    or    x³ + 1 = 0
                        - 1  - 1
                         x³ = -1
                          x = -1

Find the equation of the line that is perpendicular to y = two over three x and contains the point (four,-eight)
Sophie [7]
When it is perpendicular, the slope is the negative reciprocal so it would equal -3/2x. Plug in the points to the equation so you can find the intercept. -8=-3/2(4)+b
Combine: -8=-6+b
Add 6: -2=b
The equation would be f(x)=-3/2x-2
Hope this helped and sorry if I am wrong!
