Answer:

Additive property

Step-by-step explanation:

Given

x - 5 = -14

Required

The property used

In the 2nd step, 5 was added to both sides, i.e.

x - 5+5  = -14 + 5

<em>The above is an illustration of additive property of equality, i.e. Adding or subtracting the same variable or constant to both sides of an equation</em>

natulia [17]

Answer:

2 2/3

Step-by-step explanation:

Make them into improper fractions first.

11/2 - 17-6

Then multiply 11/2 so that they have common denominators.

33/6 - 17/6

Then solve.

33/6 - 17/6 = 16/6

Then convert back into a mixed number.

2 4/6 or 2 2/3

What’s is the slope of the lin
Lady bird [3.3K]

Answer:

1/3

Step-by-step explanation:

<em>Method 1.</em>

slope = rise/run

Rise is vertical distance.

Run is horizontal distance.

Find two points that are easy to read (on grid intersections):

(2, -1) and (5, 0).

Start at (2, 1). You need to go to (5, 0) by moving only vertically and horizontally. Go up 1 unit. That is a rise of 1. Now go right 3 units. That is a run of 3.

rise = 1

run = 3

slope = rise/run = 1/3

<em>Method 2.</em>

Use the slope formula and two points on the line.

slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}

Use points (2, -1) and (5, 0).

slope = m = \dfrac{0 - (-1)}{5 - 2}

slope = m = \dfrac{0 + 1}{3}

slope = m = \dfrac{1}{3}

slope = 1/3
