You do 4x — 2x which equals 2x then you do -2 —4 which equals -6 then you have 2x=-6. so you divide -6/2 and your answer is X=-3. Oh you check by replacing the Xs with -3 and see if the equation is true.

Answer:X=3

Step-by-step explanation:

4x + (-2) = 2x + 4 -- First you need to isolate the x by adding 2 to both sides and subtracting 2x from both sides.

4x + (-2) = 2x + 4

-2x +2 -2x +2

2x + 0 = 0 + 6 or 2x = 6 -- Now you divide both sides by 2

/2 /2

1x = 3 or x=3 -- This is your answer. Now plug 3 back in to check if you are correct.

4(3) + (-2) = 2(3) + 4

12 + (-2) = 6 + 4

10 = 10 -- So, x=3 is correct. Hope I explained it ok for you?

(3,4) and (12,19) find the equation of the line that passes through it

harina [27]

Answer:

The equation of the line will be:

$y=\frac{5}{3}x-1$

Step-by-step explanation:

Given the points

(3, 4)

(12, 9)

Finding the slope between (3, 4) and (12, 9)

$\left(x_1,\:y_1\right)=\left(3,\:4\right),\:\left(x_2,\:y_2\right)=\left(12,\:19\right)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{19-4}{12-3}$

$m=\frac{5}{3}$

The equation of the line can be obtained using the point-slope form of the equation of the line

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 5/9 and the point (3, 4)

$y-4=\frac{5}{3}\left(x-3\right)$

$y-4+4=\frac{5}{3}\left(x-3\right)+4$

$y=\frac{5}{3}x-1$

Therefore, the equation of the line will be:

$y=\frac{5}{3}x-1$

PLEASE HELP ME!!! The students in Suzanne's school are painting a rectangular mural outside the building that will be 15 feet by

Andrew [12]

Answer:

length of scale drawing = 9 feet

width of scale drawing = 3 feet

Step-by-step explanation:

Actual dimension 15 feet by 45 feet.

length = 45 feet

width = 15 feet

Dimension on drawing is 20% of actual dimension.

20% = 20/100

Thus,

20% of 15 feet = 20/100 * 15 feet = 3 feet

20% of 45 feet = 20/100 * 45 feet = 9 feet

Thus, length of scale drawing = 9 feet

width of scale drawing = 3 feet
