Answer:

The tree is 17.5 ft tall

Step-by-step explanation:

We can use ratios to solve

Shadow

-----------

height

28          8

------ = ------------

tree         5

Using cross products

28*5 = 8 * tree

140 = 8 * tree

divide each side by 8

140/8 = 8 *tree/ 8

17.5 = tree

Vanyuwa [196]

Answer:

(-3,-4)

Step-by-step explanation:

● (-1,-8) => (0,-11)

Notice that to move from -1 to 0 in the x-axis we should go one unit to the right wich means adding 1.

● -1 + 1 = 0

Notice that to move from -8 to -11 in the y-axis we should go 3 units down wich means substracting 3.

● -8-3 = -11

Let's do the same for the second point.

● (-4,-1) => ?

Add 1 to -4

● -4+1 = -3

We moved 1 unit to the right by adding 1

Substract 3 from -1

● -1-3 = -4

We moved down 3 units by substracting 3

So the image of (-4,-1) is (-3,-4)
