Answer:
Answer:
a. ----> $10
b. ----> $110
Step-by-step explanation:
Step-by-step explanation:
principle ( p ) = $100
time ( t ) = 10 years
rate ( r ) = 11%
simple interest = (p × r × t)÷ 100
= ( $100 × 11 × 10 )÷ 100
= 11000 ÷ 100
= $110
interest = simple interest - principle
interest = $110 - $100
= $10
Answer:
y = 12^8
Step-by-step explanation:
Log base 12, y^2 = 16
y2 = 12^16
y = sqrt ( 12^16) = (12^16)^1/2
y = 12^8
Answer:
Y=7+3x, x=-3, y=-2
Step-by-step explanation:
3x-5y=1. Equation 1
3x-y=-7. Equation 2
-y=-7-3x isolate for y in equation 2
y=7+3x multiplied by -1 to get positive y
3x-5(7+3x)=1 substitute y value of equation 2 (7+3x) into equation 1
3x-35-15x=1
-12x=36
x=-3
solve for y.
3x-5y=1
3(-3)-5y=1
-9-5y=1
-5y=10
y=-2
