Slope intercept form of 12x-y=4

Mathematics
1 answer:
Nata [24]3 years ago
8 0

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

<em>Hope I helped! :) </em>

8x+20y=-120 as slope
Temka [501]

Answer:

y = -2/5x -6

slope is -2/5

y intercept -6

Step-by-step explanation:

8x+20y=-120

Slope intercept form is y = mx+b where m is the slope and b is the y intercept

Subtract 8x from each side

8x -8x+20y= -8x-120

20y = -8x - 120

Divide by 20

20y/20 = -8x/20 -120/20

y = -2/5x -6

If i purchase a product for $79.99 and two accessories for 9.99 and 7.00 how much will i owe after taxes applies 8.75%
ehidna [41]

Answer:

The price will be $105.47

Step-by-step explanation:

Given that i purchase a product for $79.99 and two accessories for $9.99 and $7.00. we have to find how much will i owe after taxes applies 8.75%

Now, the cost price of the product and the two accessories will be

$79.99+$9.99+$7.00

= $96.98

Now, also the tax applies at the rate 8.75%

∴ Tax=8.75\%\thinspace of\thinspace96.98

               =8.48575=8.49(approx)

Hence, the price which i owe after taxes will be $96.98+$8.49=$105.47

Algebraic equations<br><img src="https://tex.z-dn.net/?f=x%20%2B%2020%20%3D%20100" id="TexFormula1" title="x + 20 = 100" alt="x
Setler [38]

Answer:

x = 80

Step-by-step explanation:

The whole reason algebra exists is to solve for a variable. Therefore, the only way to get x by itself or to see what x equals is to subtract 20 from both sides. Doing this will make x be all alone on one side of the equation and to see what x is.

x + 20 = 100

x + 20 -20 = 100 -20

x = 80
