Answer:
5%
Step-by-step explanation:
To find the tax, we take the price times the tax rate
2 = 40* rate
Divide each side by 40
2/40 =rate
.05 = rate
Changing to percent form
5% = rate
Hey there! :)
Please keep in mind that slope-intercept form is : y=mx+b ; where m=slope, b=y-intercept
Using this, we can isolate y in our original given equation.
12x - y = 4
Start off by subtracting 12x from both sides.
-y = -12x + 4
Divide both sides by -1.
-y ÷ -1 = (-12x + 4) ÷ -1
Simplify!
y = 12x - 4
Therefore, using the slope-intercept form, we can come to the conclusion that because 12 is located in the "m" slot and "m=slope" then 12 is our slope. In addition, -4 is our y-intercept because it is located on the y position.
Slope = 12
Y-intercept = -4

Answer:
y=-3x-5
Step-by-step explanation:
6x+2y=-10
2y = -6x-10 (you need to isolate the y and so i took 6x and subtracted it from both sides)
y = -6/2x-10/2 ( dont feel like explaining)
divide them (-6/2 and -10/2) to get
y=-3x-5

I'm pretty sure you would multiply the cost amount to the percentage
