A real world example of this equation might look something like this:
John Smith wanted to subscribe to Vague Co. In order to subscribe, there is an initial fee of $60, and an additional fee of $25 for each month that he's subscribed. However, John found another company he wanted to subscribe to, Random Inc., which had an initial fee of $20 and an additional fee of $35 per month. After doing a bit of math, John found that the cost to subscribe to both companies is equal for x months. How many months would it take for the costs of both subscriptions to be equal?
60 + 25x = 35x + 20 Given
60 = 10x + 20 Subtract 25x from both sides
40 = 10x Subtract 20 from both sides
4 = x Divide both sides by 10
It would take 4 months for the costs of a subscription to Vague Co. and Random Inc. to be equal.
9 x 2 = 18
6 x 3 = 18
and 18 x 1 = 18
Answer:
y= -2x
Step-by-step explanation:
To find the slope, convert the standard form of the equation into slope intercept form, y=mx+b.
5x-10y=-12
-10y=-5x-12
y=1/2 x + 1.2
The slope is 1/2 and the slope of the new line will be -2 because the negative reciprocal create a perpendicular line. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-8)=-2(x--4)
y-8=-2(x+4)
y-8=-2x -8
y= -2x +0
