Find the slope of the line using the equation (y1-y2)/(x1-x2), which is change in rise over change in run. use any two points, for example (2,-2) and (3,-1). using the formula, (-2-(-1))/(2-3) is the rate of change, giving you -1/-1 as the slope, which is -1. the rate of change is -1.

Answer:

<h2>The x-coordinate after the rotation is -10.</h2>

Step-by-step explanation:

A 810° rotation is equal to a 90° rotation. So, the transformation described gives the same result than rotating 90° only.

A 90° counterclockwise rotation is defined by the rule

(x,y) \implies (-y,x)

The given coordinate is (8,10). Using the rule, we have

(8,10) \implies (-10,8)

Therefore, the x-coordinate after the rotation is -10.

The price of a computer was decreased by 30% to £336. What was the price before the decrease?
Goryan [66]

Answer:

£480

Step-by-step explanation:

x = the original price of a computer

£x = 100% of the original price

The price of a computer was decreased by 30% to £336.

This means:

£336 = 100% - 30%

£336 = 70% of the original price

From this, we will find 1% of the original price.

£336 ÷ 70 = 1%

£4.8 = 1%

Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.

£4.8 × 100 = 100%

£480 = 100%

Therefore, the original price of a computer = £480
