Answer:

A’ (6,-2)

B’ (1,3)

Step-by-step explanation:

Here, we want to give the coordinates after a counterclockwise rotation of 90 degrees

Given a point with coordinates (x,y)

A counterclockwise rotation at 90 degrees to the origin will yield the coordinates (-y,x)

So A (-2,-6) will be A’ (6,-2) while B (3,-1) will be B’ (1,3)

Answer:

No

Step-by-step explanation:

If the lines are perpendicular then they will be the negative reciprocals of each other.

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)

m_{PQ} = \frac{-12+10}{-5+8} = - \frac{2}{3}

Repeat the process with

(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)

m_{RS} = \frac{-5+6}{17-9} = \frac{1}{8}

The slopes are not the negative reciprocal of each other, thus they are not perpendicular.

Given [Missing details]

Spencer's expenses

Clothing = 27\%

Gasoline = 11\%

Food = 44\%

Entertainment = 18\%

Total= \$704.00

Required:

An estimate for the amount spent on clothing

To do this, simply multiply the clothing percentage by the total amount.

Clothing = 27\% * \$704.00

Clothing = 0.27 * \$704.00

Clothing = \$190.08

Approximate

Clothing = \$190.0
