Find the missing length. round to the nearest tenth, if necessary.

a. 12
b. 17.7
c. 19
d. 22.45

B 17.7

Step-by-step explanation:

A^2+B^2=C^2 So

B^2= C^2-A^2

B^2= 19^2-7^2

B^2= 319

B=17.7

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

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer
