What is the coordinate rule for a dilation centered at (0,0) with a scale factor of 3?

15 points

no picture given.

(0,0)

Step-by-step explanation:

To find the scale factor of coordinates, you have to multiply the x and y by the scale factor, which is 3.

0 × 3 = 3

0 × 3 = 3

Answer is (0,0)

The rule would be : (x, y) --> (3x, 3y).

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
