X would equal 9. Subtract 18 from both sides then divide by two to get 9 as X
The answer is $10 the first month they can do it
Answer:
y=\frac{1}{2}x-2
Step-by-step explanation:
we are given
Line is perpendicular to y=−2x−6
we can compare it with
y=mx+b
where
m is slope
so, m=-2
so, slope is -2
Our line is perpendicular to this slope
so, slope of our line will be
now, we are given point as (6,1)
so,
now, we can use point slope form of line
we can plug values
now, we can solve for y
and we get
Let x=annual interest rate of 18000 investment.
Then
18000*x - 9000(x-0.006)=648
Solve for x
18000x-9000x+9000*0.006=648
9000x=648-54=594
x=594/9000=0.066
Answer:
the annual interest rate of the 18000 investment is 6.6%
the annual interest rate of the 9000 investment is 6.0%
Answer : -18 is the coefficient
