What’s the answer? I can’t divide anything if it’s just x. Example: 12x+24x+30 = 467. Then you can just divide the numbers after they are added up to see what x equals. 30 and 24x + 12x won’t go together because they have x, 30 doesn’t. Move your x’s to Texas.

This table gives a few (x,y) pairs of a line in the coordinate plane
umka21 [38]

Answer:

-41

Step-by-step explanation:

Use 2 points to find the equation of the line using the 2-point form of the equation of a line. Then we write the equation in the slope-intercept form to find the y-intercept.

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

We can use points (-36, -117) and (-27, -98), so

x1 = -36

x2 = -27

y1 = -117

y2 = -98

y - (-117) = \dfrac{-98 - (-117)}{-27 - (-36)}(x - (-36))

y + 117 = \dfrac{19}{9}(x + 36)

y + 117 = \dfrac{19}{9}x + 76

y = \dfrac{19}{9}x - 41

The y-intercept is -41.

Are the graphs of the lines in the pair parallel? Explain.<br><br> y = 5x + 6<br> –18x + 3y = –54
raketka [301]
I hope this helps you



y=5x+6 this lines slope= -5


-3 (6x-y)= -54


6x-y= 18

y= 6x-18 this lines slope= -6


parallel lines slopes equal

-5 is not equal -6 not parallel

Which expression will you generate if you combine the like terms in 5x + 6x + y + y + 3y + 4 + 6 + 2?
Anika [276]

Answer:

5x and 6x both have the letter x. Let's combine them! 5x+6x = 11x

y, y, and 3y all have the letter y. You can imagine y to be 1y, they're the same.

1y + 1y + 3y = 5y

4, 6, and 2 don't have any letters. 4 + 6 + 2 = 12

Now you have to put all the final terms together to get: 11x + 5y +12
