Step-by-step explanation:

(4-2)^3-3 \times 4

Brackets or parenthesis are to be evaluated first. Subtract the numbers in the brackets.

(2)^3-3 \times 4

Evaluate the power or exponent.

8-3 \times 4

Multiply the numbers.

Answer:

<h2>-4</h2>

Option B is the correct option.

Step-by-step explanation:

{(4 - 2)}^{3}  - 3 \times 4

Subtract the numbers

=  {(2)}^{3 } - 3 \times 4

Multiply the numbers

=  {(2)}^{3}  - 12

Evaluate the power

= 8 - 12

Calculate the difference

=  - 4

Hope this helps..

Best regards!!

Find the equation of the perpendicular bisector of a line segment whose end points are (-3,9) and (-1,5)
timofeeve [1]

First find the equation of y.

y=mx+n=\frac{\Delta y}{\Delta x}x+n

Find the slope m.

m=\frac{5-9}{-1-3}=\frac{-4}{-4}=1.

Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.

9=1(-3)+n\implies n=12.

The equation of a line y is:

y=x+12.

The perpendicular line y_{\perp} is same like the normal line except its slope m becomes:

k=-\frac{1}{m}=-1.

The equation of a perpendicular bisector is thus:

y_{\perp}=-x+12.

Hope this helps.
