Find the solution set of the following quadratic equations by completing the square. 1.) x^2 - 10x + 1 = 0
2.) 4x^2 - 8x = 12

Step-by-step explanation:

1)

2)

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

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
