1. Point V is somewhere on the line segment UW. If UV = 8 then find the length of VW.

VW = 3

Step-by-step explanation:

From the diagram, we know that UW = 11.

We also know that UV + VW = UW, because UW is the length of the whole segment.

Using substitution (knowing 2 of the line segments), we find that 8 + VW = 11.

If we subtract 8 from both sides using inverse operations, we find that VW = 3, which is the answer.

Hope this helps!

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
