In order to do this you first have to solve the parenthesis. Why because the pemdas tells you so, first parenthesis then exponents then multiplication then division then addition and then subtraction. So first subtract 7 from 9 to get (2)^-3 now multiply 2 3 times. -2*-2*-2 to get -8

Hope this helps

What is the slope of a line perpendicular to the line whose equation is 6x+2y=−32. Fully simplify your answer.
Reika [66]

The slope of the line that is perpendicular to 6x + 2y = -32 is: 1/3.

<h3>What is the Slope of Perpendicular Lines?</h3>

The slope of two lines that are perpendicular to each other will always have a product that is equal to -1, which means that their slopes are negative reciprocals to each other.

Rewrite 6x + 2y = -32 in slope-intercept form:

2y = -6x - 32

2y/2 = -6x/2 - 32/2

y = -3x - 16

The slope is -3. Negative reciprocal of -3 is 1/3.

Therefore, the slope of the perpendicular line would be: 1/3.

What is the equation in point-slope form of a line that passes through the points (−4, −1) and (5, 7) ? y+1=89(x+4) y+4=98(x+1)
maria [59]

The point-slope formula:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-4, -1) and (5, 7).

Substitute:

m=\dfrac{7-(-1)}{5-(-4)}=\dfrac{7+1}{5+4}=\dfrac{8}{9}\\\\y-(-1)=\dfrac{8}{9}(x-(-4))\\\\\boxed{y+1=\dfrac{8}{9}(x+4)}
