Answer:
y = -6 + 2x
Step-by-step explanation:
Answer: A
Step-by-step explanation:
2 x
----- = ------
3 15
cross multiply
(3)(x) = (15)(2)
3x = 30
x = 30/3
x = 10
so 2/3 = 10/15.......notice how these are equivalent fractions....that is because proportions are nothing but equivalent fractions
(x² + 16x)² = 17²
√x² + 16x)² = √17²
(x² + 16x) = (+-)17
1st equation: x²+16x-17 = 0
2nd equation:x²+16x+17 =0
Let's solve these 2 quadratic equation:
1st equation x' =1 & x" = - 17
2nd equation x'= (-8+√47) & x" =(-8-√47)

(x,y)
(-3,y)
x=-3
y=y
y=3-(-3)
y=3+3
y=6
y=6 which is mysteriously not listed
