How do you know which direction to move on a number line when adding integers?

Doss [256]

Step-by-step explanation:

To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.

What is the equation in point-slope form for the line parallel to y=-8x - 5 that contains j(-2, 9)

Julli [10]

Answer:

y - 9 = -8(x + 2)

Step-by-step explanation:

What is the equation in point-slope form for the line parallel to y=-8x - 5 that contains j(-2, 9)

Step 1

y intercept =

y = mx + b

y=-8x - 5

m = -8, b = -5

Point slope form

y - y1 =m( x - x1)

We are given coordinates:

j(-2, 9) = (x1, y1) where ,

x1 = -2

y1 = 9

Hence, our point slope form equation is:

y - 9 = -8(x -(-2))

y - 9 = -8(x + 2)

What is H in the algebraic expression H+340÷30=25

disa [49]

Answer:

H = 13.67

Step-by-step explanation:

Given:

The the algebraic expression is

$H + \frac{340}{30} = 25$

We need to write the above equation for h.

Solution:

$H + \frac{340}{30} = 25$

First we divide the fraction part of the equation by common factor 10.

$H + \frac{34}{3} = 25$

Subtract both side of the equation by $\frac{34}{3}$ .

$H + \frac{34}{3}-\frac{34}{3} = 25- \frac{34}{3}$

$H = 25- \frac{34}{3}$

To write 25 as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$H = 25\times \frac{3}{3}- \frac{34}{3}$

$H = \frac{25\times3}{3}- \frac{34}{3}$

$H = \frac{75}{3}- \frac{34}{3}$

$H = \frac{75-34}{3}$

$H = \frac{41}{3}$

$H = 13.67$

Therefore the value of H is 13.67.
