Given a=-3 b=4 and c=-5 evaluate -|a-b| + c

2

Step-by-step explanation:

given that

a = -3

b = 4

c = -5

so, to evaluate for this expression   -|a-b| + c simply insert the value of the variables and then evaluate , but always take note of the signs.

-(a-b) + c

- ( -3 - 4) + (-5)

use the negative sign - to open the bracket

note that

- x - = +

- x + = -

+ x + = +

so , from

= - ( -3 - 4) + (-5)

= 3 + 4 - 5

= 7 - 5

= 2

therefore the expression is evaluated tho b 2

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).
