NUMBER 7 PLEASE HELP AND I U CAN PLS SHOW WORK

∠LMP + ∠NMP = ∠NML

∠LMP = 11 + x

∠NMP = x

∠NML = 137

11 + x + x = 137

11 + 2x = 137

-11           -11

2x = 126

/2       /2

x = 63°

∠LMP = 11 + x = 11 + 63 = 74°

∠NMP = x = 63°

Step-by-step explanation:

hm let me think hm think think hm think yes

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
