At Westside, class fees are $98 per credit hour, and at Pinewood, class fees are $115 per credit hour. Ann is taking a combined total of 20 credit hours at the two schools. Suppose that she is taking w credit hours at Westside. Write an expression for the combined total dollar amount she paid for her class fees.

y = 98(w) + 115(20 - w).

Step-by-step explanation:

Ann takes a combine 20 credit hours, and she is taking w credits at Westside, this means that she has to take the rest at Pinewood.

(total credits at Westside)($98) + (total credits at pinewood)($115).

Assuming that she takes all credits at Westside then we say

20(98) + 0, and this is the lowest cost it will be

Assuming she takes all credits at Pinewood, then we say

0 + (20)(115) and this will be the maximum she would pay for 20 credits.

Let y be the total cost of her courses, then we say

y = 98(w) + 115(20 - w).

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
