Answer:

3x+5

Step-by-step explanation:

Since you can't add 5 with x or 2x, the only way you can simplify is by adding the x and 2x together. x is basically 1x, so you get 3x.

3x + 5

Just combine like terms. The like terms are 2x and x. You can also write x as 1x. The sign is addition so you at 2x + 1x and get 3x. So now you have 3x + 5,you can’t add 3x + 5 cause they aren’t like terms so that’s your answer. :)

Passes through (-8, -7), parallel to the graph of y=1/2x-3

KIM [24]

Answer:

$y=\frac12x-3$

The answer is the same line as given in the question.

Step-by-step explanation:

Hello!

Slope-intercept Form: $y = mx + b$

y = output
m = slope
x = input
b = y-intercept

Given our Line: $y=\frac12x-3$

slope = $\frac12$
y-intercept = $3$

Parallel lines have the same slope but a different y-intercept, so the second line should have a slope of $\frac12$ .

To find the y-intercept, we plug in the x and y values from the point into a blank equation with the slope and solve for b.

$y = \frac12x + b$
$-7 =\frac12 (-8) + b$
$-7 = -4 + b$
$-3 = b$

The equation is $y=\frac12x-3$ , hence the same line.

Substitute (2, 1) into x + 3y = 5 to get ✔ 2 + 3(1) = 5 . Simplify the equation to get . Substitute (2, 1) into y = –x + 3 to ge

nikdorinn [45]

Answer:

See explanation

Step-by-step explanation:

x + 3y = 5

(x, y) = (2,1)

x + 3y = 5

2 + 3(1) = 5

2 + 3 = 5

5 = 5

The equation is true

y = –x + 3

(x, y) = (2, 1)

y = –x + 3

1 = -2 + 3

1 = 1

The equation is true
