x = 5

Step-by-step explanation:

In triangle CDE, the side lengths 7 and 9 corrospond with the side lengths 14 and 3x + 3 in triangle UVW.

To find the value of x, we first need to understand the dilation rate.

14 / 7 = 2

2 is the dilation rate

Evalutate 9 * 2 = 18

This means that 3x + 3 = 18

Time to find the value of x

Subtract 3 from both sides

3x + 3 - 3 = 18 -3

3x = 15

Divide 3 from both sides

3/3 x = 15/3

x = 5

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

answer: 59
