Plz hurry it's !
what is the union of the two sets r = {10, 11, 13, 15, 17} and t = {5, 7}?

{5, 7, 10, 11, 13, 15, 17}

null set

{5, 7}

{15, 17}

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

okay wait before i answer, is this for your points on a graph?

angle addition postulate

2x=56
