Find the missing value.

- (-5) = -7

x=−12

Explanation:

x−(−5)=−7

Step 1: Simplify both sides of the equation.

x+5=−7

Step 2: Subtract 5 from both sides.

x+5−5=−7−5

x=−12

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: the answer is 35%
