Compatible numbers are numbers which are easy to do mental calculation. For example is when doing division like 25 and 5, 100 and 10, and 36 and 6.

First, we know that: 7 pounds=5 pounds + 2 pounds

                                or 7=5+2

In mathematics, the word “of” means to multiply. So:

                                grapes given away = 7  * (2/5)

Replacing 7 with 5 and 2:

                                                                = (5+2)*(2/5)

Using the distribution principle:

                                                =5*(2/5) + 2*(2/5)

                                                =2+ 4/5

                                =2 4/5

So grapes given away is 2 4/5 pounds.

<span>2/5 is close to 1/2, and it is easy to find 1/2 of 7 mentally. Half of 7 is 3.5, so Martin gave away about 3.5 pounds.</span>

Can someone help me out please
Brums [2.3K]

Answer:

D. g(x) = (x - 5)² + 3

Step-by-step explanation:

If a graph is translated horizontally, the value will affect x inside of the parentheses. For example, (x + #) or (x - #).

If a function is translated to the right, there will be a (-) sign. If a function is translated to the left, there will be a (+) sign.

This function needs to be translated 5 units to the right. Therefore, the equation will be: g(x) = (x - 5)² + 3
