Lisa has a new puppy. The puppy weighs 5 pounds less than one-third the weight of Lisa's dog. Together, the dog and the puppy weigh 31 pounds. Which system of
equations could be used to find the weight of each animal?
A y=1/3x - 5
с
= 3x + 5
y = x + 31
y = x + 31
By={x-5
Dy= 1x + 5
y = -x + 31
y = -x + 31

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

22 and 22
