9x-3y=31 One equation in a system of two linear equations is shown above. The graph of the second equation in the xy-plane has a slope of the 4. How many ordered pairs (x, y) satisfy both equations?

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

0.038
