Solve for c. (c+9)2=64 a/1 and 17 b .−55−−√ and 55−−√ c−73−−√ and 73−−√ d −17 and −1

c = -9 ±√8

Step-by-step explanation:

You can solve for (c+9)²=64 by using inverse operations. Since the expression (c + 9) is under the operation of squaring, use a square root on both sides to undo it. Then continue using inverse operations to solve for C.

(c+9)²=64

√(c+9)² = √8

(c + 9) = ±√8

c = -9 ±√8

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.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
