Answer:
4,7 is the one not equalivent to the others.
Step-by-step explanation:
All of the y values in the ratios have a gcf of 12. 7 Is not divisible by 12, let alone 9.
This is the grid of 3y - 4x = 12
Y = 1/4x....slope here is 1/4. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, " flip " the number and change the sign. So the negative reciprocal for our perpendicular line is -4.
y = mx + b
slope(m) = -4
(2,-5)...x = 2 and y = -5
now we sub and find b, the y int
-5 = -4(2) + b
-5 = -8 + b
-5 + 8 = b
3 = b
so ur perpendicular equation is : y = -4x + 3
Step-by-step explanation:
32x^3 - 32x^2 + 8x
= 8x(4x^2 - 4x + 1)
= 8x(2x - 1)^2.
