I have to solve each system algebraically y = x -8 y=5x

x=-2, y=-10

Step-by-step explanation:

Since both equations are equal to y, we can set them equal to each other and solve

x-8=5x

Subtract x from both sides

-8=4x

Divide both sides by 4

x=-2

Next, we need to find a y

Substitute -2 in for x in one of the equations and solve

y=5x

y=5*-2

y=-10

x=-2, y=-10

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

no solution

step-by-step explanation:

there is not enough information in the problem to solve.
