Six times the sum of a number and 9 equals 3

6(x + 9) = 3. x = -7

Step-by-step explanation:

if you distribute first it gives you 6x + 45 = 3 then you subtract 45 from each side which gets you 6x=-42 then divide by 6 to get x = -7.

find out the value of b

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
