Evaluate (x3 − 15) − (y + 6) for x = 4 and y = 1.

42

Step-by-step explanation:

Open the bracket first

(X3-15)-(y+6)

X3-15-y-6

Collect like terms

X3-y-15-6

X3-y-21

And x is said to be 4,y to be 1

So let's substitute

(4)^3-(1)-21

64-1-21

64-22

42

Therefore the final answer is 42

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
