The angles with measures x and (4x) are complementary angles.

Which is the value of x?

x = 18

Step-by-step explanation:

Complementary means the angles add to 90

x + 4x = 90

5x = 90

5x/5 = 90/5

x = 18

The larger angle is 4*18 = 72

2y+y=5

add 2y and y

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
