If y varies directly with x and y is 9 when x is 5, what is x when y is -1

We use the fact that y = kx, where k is the constant of proportionality.

9 = 5k

9/5 = k

Now that we know k, we can find x when y = -1.

-1 = x(9/5)

-1/(9/5) = x

-5/9 = x

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

the answer is simply just 6n add the two together as they have an n
