Consider similar figures QRS and TUV below where QRS is the pre-image of TUV What is the scale factor?

The scale factor is 2.5 to 1 which is 1/2.5

Step-by-step explanation:

Here, we want to get the scale factor in the given image

The scale factor we want to get is from the big to the small triangle

To get this, we find the ratio of the sides which are the same

Thus, we have ;

7/2.8 = 2.5

So the scale factor in this case is 2.5 to 1

step-by-step explanation:

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
