Ineed with # nine.. i don’t get it ug

Just plug in the x value in the equation to find f(x). The x value is the domain, the f(x) value is the range
so when x=-4, f(-4)=(2/5)(-4)+5=17/5
when x=-2, f(x)=21/5
when x=0, f(x)=5
when x=3, f(x)=31/25
so the range is {17/5, 21/5, 5, 31/25}

5 and one-third units

Step-by-step explanation:

In the given question, we are given the following values:

The length of W Y = 4

The length of Y X = a

The length of Z Y = 3

We are to find a

From the describe diagram above, we would have the following

WY:ZY = YX :WY

WY/ ZY = YX/WY

4/3= a/4

Cross Multiply

4× 4 = 3a

Divide both sides by 3

a = 16/3

a = 5 1/3 units

a = 5 and one third units
