Number 11 is slope=3, then number 12 is slope=-2, then number 13 is slope=4 and number 14 is slope =1. i got my answers by looking at the x axis. In a y=mx+b whatevers infront of the x is your slope. idk what 15 is though its weird lol Good luck! :)
Answer:
3.6
Step-by-step explanation:
I think that is the answer but im not 100 percent sure
C, I remember doing this test
Answer:
√(2 - 7x) + 2x = 0
√(2 - 7x) = - 2x
[√(2 - 7x)]² = (- 2x)²
2 - 7x = 4x²
4x² + 7x - 2 = 0
4x² + 8x - x - 2 = 0
4x(x + 2) - (x + 2) = 0
(4x - 1)(x + 2) = 0
4x - 1 = 0 => 4x = 1 => x₁ = 1/4
x + 2 = 0 => x₂ = - 2
