What's. Y+1=2(x-5) in Ax+by=c form

1 answer:

4 0

Y + 1 = 2(x - 5)....distribute the 2 thru the parenthesis
y + 1 = 2x - 10...subtract 1 from both sides
y = 2x - 10 - 1
y = 2x - 11....subtract 2x from both sides
-2x + y = -11 ...multiply by -1 to make A positive
2x - y = 11 <===

Answer: $C=270x+2200$

Step-by-step explanation:

Given

Cost per student in the year 1978 is $2200

The cost increases to $10,300 in 2008

Suppose $C=mx+a$ is the linear equation defining the cost per student after x years

Substitute the value for 1978

$\Rightarrow 2200=m(0)+c\\\Rightarrow c=2200$

After 30 years it becomes

$\Rightarrow 10,300=m(30)+2200\\\Rightarrow 30m=8100\\\Rightarrow m=270$

Thus, the linear equation becomes

$\Rightarrow C=270x+2200$
