How do you use elimination in 4x-3y=8 and 5x-2y=-11
1 answer:
4x - 3y = 8 ⇒ 8x - 6y = 16 5x - 2y = -11 ⇒ 15x - 6y = -33 -7x = 49 -7 -7 x = -7 4x - 3y = 8 4(-7) - 3y = 8 -28 - 3y = 8 + 28 + 28 -3y = 36 -3 -3 y = -12 (x, y) = (-7, -12) To use elimination you have to multiply the first graph by 2 and the second graph by 3 so that the two y-axis can be equal to -6. Then you do the rest to find the answer of the x-axis and the y-axis.

Your x-intercept is (12/5,0) and your y-intercept is (0,-4)
The answer is 0.5. X is the input and f(x) is the output. Between -3 and -2 the difference is 0.5. Because it goes from -0.5 to 1
