(, i’m stuck)
which of the following equations is an example of direct variation between
variables x and y?

What are the measures of ∠a, ∠b, ∠c and ∠d? explain how to find each of the angle measure.

Evaluate the expression for the given value of the variable 7a - 4a for a =8

50 plz, given the system of equations, match the following items. x + 3 y = 5 x - 3 y = -1 a) x-determinant b) y-determinant c) system determinant match the following to the pictures below.
