7/9p+8/3= -p
What does p =next to 7/9

P = -1.5

7/9p = (7÷9) × -1.5 = -1.1666666667

Step-by-step explanation:

7/9p + 8/3= -p

7/9p + p = -8/3

(7p + 9p) ÷ 9 = -8/3

16p/9 = -8/3

Cross multiply

16p × 3 = -8 × 9

48p = -72

p = -72/48

p= -1.5

Therefore,

7/9 (-1.5) + 8/3 = -(-1.5)

-1.1666666667 + 2.6666666667 = 1.5

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

i believe the answer is d.

hope it you! : d
