Simplify: 5 - 2x - 3 + x 2 - 6 1 2 - 2x x - 2

Combine like terms. Note that some numbers are constants, while others have variables.

5 - 3 = 2

x - 2x = -x

-x + 2 should be your answer

Hope this helps

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
