SOMEONE, PLEASE HELP ME WITH THIS PLSSSS
Stels [109]

Answer:

Step-by-step explanation:

1. You can use the intercepts to graph the line. The graph of 2x + 3y = 12      crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12  crosses the y-axis at (0, 4), so its y-intercept is 4.

2. Point-Slope Form: y - y1 = m(x - x1)

Standard Form: ax + by = c

5x - 2y = 10

-2y = -5x + 10

y = (5/2)x - 5    The slope is 5/2.

y - 2 = (-5/2)(x - 10)

y = (-5/2)x + 25 + 2

y = (-5/2)x + 27      The slope is -5/2.

y = (-5/2)x - 10     The slope is -5/2.

If x varies directly with y and x = 3.5 when y = 14, find x when y = 18.
maks197457 [2]

Answer:

x = 4.5

Step-by-step explanation:

there's definitely other ways to solve this, but I used a proportion.

\frac{3.5}{x} = \frac{14}{18}

Then you can make this equation:

14x = 3.5 * 18

I solved for it and got 4.5 .

Determine whether 4 is a solution of the equation 9x+7=40.<br> Is 4 a​ solution?
Allisa [31]

Plug in 4 for x

9(4) + 7 = 40

36 + 7 = 40

43 ≠ 40

No, 4 is not a solution

hope this helps
