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

b) 4x^2 and -3x^2 and y^2
Hello here is a solution :
let A(-6;4) O(0;0) B(x; 0)
i'have : OA² = OB²+AB² ( pytagore theorem)
OA² = (-6-0)² +(4-0)² = 36 +16 =52
OB² = (x-0)² + (0-0)² = x²
AB² = (x+6)² +(0-4)² = x²+12x+36 +16 = x²+12x+52
52 = x² + x²+12x+52
2x² +12x=0
2x(x+6) =0
2x=0 or x+6 = 0
x=0 or x= -6
conclusion : x = -6
if x = 0 i' have not the <span>triangle</span>
