Answer:

(-2, -3)

Step-by-step explanation:

90° clockwise rotation:

(x, y) -----> (y, -x)

Let's apply this to our coordinates:

(x, y) -----> (y, -x)

(3, -2) -----> (-2, -3)

Simply make the old y-coordinate the new x-coordinate, and make the old x-coordinate negative and make the new y-coordinate.

Therefore, the coordinate of the new point is (-2, -3).

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (0, 7)

Point (-3, 0)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{0-7}{-3-0}$
Subtract: $m=\frac{-7}{-3}$
Simplify: $m=\frac{7}{3}$

Multiply (2m+3)(m^2-2m+2)

Dahasolnce [82]

Answer:

Step-by-step explanation:

The first step is to distribute the 2m and 3 to ( $m^2-2m+2$ ), like so:

$(2m+3)(m^2-2m+2)$

$2m^3-4m^2+4m+3m^2-6m+6$

Then, add like terms:

$2m^3 -m^2 -2m + 6$

A marketing campaign aims to increase sales of a product by 8% per month. If this goal is met, within 7 months the sales will re

MrMuchimi

Try this:
8% of 2570 is 2570*0.08=205.6 units
and since the number of units were increasing every month you can multiply that by seven giving you 1439.2, then you can subtract that by your final amount of sales giving you the initial amount of 1130.8 units.
