b. What scale factor did Lin apply to the Triangle \( A \) to create the copy? c. What is the length of bottom side of the scaled copy?

a) \( 4(2 x+5)= \)

The expression \( \left(y^{\frac{1}{4}}\right)^{\frac{1}{5}} \) is equivalent to \( y^{r} \) where \( r \), the exponent of \( y \), is:

Write the equation of the line that passes through the points \( (8,4) \) and \( (-9,6) \) Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.

Find the slope of the line passing through the points \( (-9,-3) \) and \( (7,-7) \)

1 Divide 150 in the ratio \( 2: 3 \). 2 Divide 72 in the ratio \( 2: 3: 4 \) 3 Divide 5 kg in the ratio \( 13: 7 \). 4 Divide 45 minutes in the ratio \( 2: 3 \). 5 Divide 1 hour in the ratio \( 1: 5 \).
