- 2(x + 3) =  - 2(x + 1) - 4 \\  - 2x - 6 =  - 2x - 2 - 4 \\  - 2x =  - 2x \\ x = x

Every x is a solution.

Alexus [3.1K]

Answer:

3, 50, 2

Step-by-step explanation:

By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.

3(n +25)= 5(10) +5(\frac{2}{5} n)

3(n +25)= 50 +2n

To find the value of n, expand the bracket on the left hand side:

3(n) +3(25)= 50 +2n

3n +75= 50 +2n

Bring all n terms to one side, constants to the other:

3n -2n= 50 -75

n= -25

Write a linear equation in slope-intercept form using a slope and a given point. If a line has a slope of short dash 2 and goes
viva [34]
<h3>Answer: Choice A</h3>

y equals short dash 2 x minus 1

In other words, y = -2x - 1 is the equation

=========================================================

Explanation:

Slope = m = -2

Point on the line is (x,y) = (1, -3)

Use these three items to find the y intercept b

y = mx+b

-3 = -2*1 + b

-3 = -2 + b

-3+2 = b

-1 = b

b = -1

The slope intercept form of y = mx+b turns into y = -2x-1 after plugging m = -2 and b = -1
