Zahra is knitting items to sell at a craft fair. She has a total of 2,640 yards of yarn. A scarf uses 200 yards of yarn, and a hat uses 150 yards. She wants to knit a minimum of 15 items. This system of inequalities represents this situation, where x is the number of scarves and y is the number of hats.
200x + 150y ≤ 2,640
x + y ≥ 15

How many scarves and hats can Zahra knit to meet her goal?

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

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
