The answer most factored would be b as 8(y-4)
Phantasy [73]2 years ago
5 0
Factor : 8y - 36

Go through all of the answer choices & see which one is correct.

a) -4 (2y + 9)

You don't even have to fully simplify this, just by looking at the -4, you already know that this is incorrect because you need to have a positive 8. So, A is incorrect. 

b) 8 (y - 4)

Simplify.

8y - 32

Incorrect because it is not equal to the original equation.

c) 2 (4y - 18)

Simplify.

8y - 36

Correct answer because it is equal to the original equation.

d) 4(2y - 9)

Simplify.

8y - 36

D is also correct.

So, your answer is : (C) and (D) are your answers.

A line includes the points (8,-2) and (-8,-4). What is the slope intercept
VladimirAG [237]

Answer:

The equation of the line would be y = 1/8x - 3

Step-by-step explanation:

to find the slope intercept form of the line, you must first find the slope. You can do this using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (-2 - -4)/(8 - -8)

m = 2/16

m = 1/8

Then you can use this slope along with either point in point-slope form. Then solve for y.

y - y1 = m(x - x1)

y + 4 = 1/8(x + 8)

y + 4 = 1/8x + 1

y = 1/8x - 3

What is tan11pi/6 ? Fraction
tamaranim1 [39]
11pi/6 is in 4th quadrant.

The reference angle is pi/6 because 11pi/6 is pi/6 radians away from 'x' axis.

In 4th quadrant, sin is negative and cos is positive, therefore tan is negative.

This means:
tan(\frac{11\pi}{6}) = -tan(\frac{\pi}{6}) = -\frac{sin(\pi/6)}{cos(\pi/6)} = -\frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}} = -\frac{1}{\sqrt{3}} = -\frac{\sqrt{3}}{3}
