Solve the following equation -4y+8=4(2y-2)-2(-16+8y)

y=4

Step-by-step explanation:

-4y+8=4(2y-2)-2(-16+8y)

or -4y+8=8y-8+32-16y

-4y-8y+16y=-8+32-8

4y=16

y=4

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
