Write the coordinate of the intercept
Basile [38]

Answer:

m = 2/3

y-intercept: 2

Explanation:

First convert this equation into standard form by distributing the 6y and -4x from the coefficient of 2, and then putting the variables in order.

This equation should be in the form: Ax + By = C (Standard form)

y = -Ax/B + C/B : y = mx + b (Slope intercept form)

2(6y - 4x) = 24 → 12y - 8x = 24

→ -8x + 12y = 24 → -8x = -12y + 24 → 8x = 12y - 24 → <em>8x - 12y = -24</em>

<u>8</u>x <u>- 12</u>y = <u>-24</u>

| | |

A B C

Once you have standard form, you are ready to convert this into slope intercept by isolating the y completely.

8x - 12y = -24

-8x -8x

(First through the subtraction property of equality, remove 8x from both sides so that -12y is by itself on the left)

-12y = -8x - 24

×-1 ×-1 ×-1

(Through the identity property of negative 1, remove the negative sign from all of the numbers because a negative times a negative is a positive)

12y = 8x + 24

(Lastly, through the division property of equality, divide all sides by 12 because it is the coefficient of y, which will solve for the variable)

No explanation needed just the answer please
Otrada [13]

Answer:

53

Step-by-step explanation:

65x- 12  = 43x + 10

65x - 43x = 10 + 12

22x = 22

x = 22/22

<u>x = 1 </u>

(65x- 12) =

65 * 1 - 12 =<u> 53</u>

43x + 10

43 * 1 -12 = <u>53</u>

Which is the missing term? (10x - 4x^2)-(7x+ ? ) = 3x-6x^2
leonid [27]

2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
