What is the greatest
common factor of 4 and 34?

2

Step-by-step explanation:

The Greatest Common Factor (GCF) is the number that both numbers share. In this case, 4 and 34 can both be divided by 2 evenly to produce an answer. However, no other number can be used to divide both numbers, making 2 the final answer.

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
