' 125% ' means ' 1.25 '
'of' means 'times'
1.25 times (last year) = $10.50
Divide each side
by 1.25: Last year = ($10.50) / 1.25
= $8.40 .
Answer:
y= 1x - 1
Step-by-step explanation:
Slope-intercept form: y=mx + b
(-4,-5) (5,4)
m= (y2 - y1)/(x2 - x1) = (4+5)/(5+4)=1
4=1(5)+b
4=5 + b 4-5=b b= -1
y= 1x - 1
You're on the right track. If they generated 380 less than 2012, then in 2013 they generated 9782-380 = 9402.
They used 10472 in 2012, so 10472+390 = 10862 used in 2013. now subtract used from produced to see how much they had to buy...
10862-10472 = 390
They had to buy 390khW from the power company.
KL + JK = 27
6x + 3x = 27
9x = 27
x = 27/9
x = 3
KL = 6x
KL = 6 × 3
KL = 18
