Is the value of the first 7 ten times as great as the value of the second 7 in 7,237

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

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

you can't solve x because it is 2 linear equation and you only have one equation
