Answer:

Coefficient = 5.

Step-by-step explanation:

$4\sqrt{3}+\sqrt{3}=5\sqrt{3}$ because since both of the numbers under the radical sign are the same, you can just add them.

Solve using the substitution method. x + 2y = 9 x + 3y = 13

Rasek [7]

x + 2y = 9

x + 3y = 13

____________________________________________________________

Solve for x in the first equation. Subtract 2y from both sides.

x = 9 - 2y

____________________________________________________________

Plug x into the second equation.

(9 - 2y) + 3y = 13

Combine like terms.

9 + y = 13

Subtract 9 from both sides.

y = 4

____________________________________________________________

Plug y back into the first equation.

x + 2(4) = 9

x + 8 = 9

Subtract 8 from both sides.

x = 1

____________________________________________________________

x = 1

y = 4

Which equation in point-slope form describes the line through points (4, –4) and (1, 2)?

IRINA_888 [86]

Step-by-step explanation:

Given points (4 , -4) and ( 1, 2)

First calculating slope (m) 

=( y2 - y1) /( x2 -x1) 

= ( 2 + 4) / (1-4)

= 6/ -3

= -2

Now

The equation in point slope form

y - y1 = m ( x - x1) 

y + 4 = -2 ( x - 4)

y + 4 = -2x + 8

2x + y - 8 + 4 = 0

2x + y -4 = 0 which is the required equation

4x – (6 – x) = 12 + 4x

devlian [24]

4x - (6-x) = 12 + 4x

4x - 6 + x = 12 + 4x

5x - 6 = 12 + 4x

5x - 4x = 12 + 6

x = 12 + 6

x = 18
