Answer:

The additive inverse of -40 is 40

Step-by-step explanation:

The additive inverseof a number is the oppositeof that number so you would change the sign.

if you need to add them it would be

(-40)+40= 0

What is an equation of the line that passes through the points (5, 5) and (5, -8)

m = undefined

General Formulas and Concepts:

Addition
Subtraction

Left to Right

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (5, 5)

Point (5, -8)

Step 2: Identify

(5, 5) → x₁ = 5, y₁ = 5

(5, -8) → x₂ = 5, y₂ = -8

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-8-5}{5-5}$
[Slope] Subtract: $\displaystyle m=\frac{-13}{0}$

Here we see that we have a number divided by 0. Since we know that we cannot divide any number by 0, our slope will be undefined. This will be a vertical line on a Cartesian plane of x = 5.

Two cell phone companies have different rate plans. Runfast has monthly charges $10 plus $4 per gig of data. B A &D’s monthl

melomori [17]

BA&D's plan is better for those who use less data. The intersection point of the two plans is (2, 18), which means that both plans cost $18 when you use 2G of data. Anything using more data than that is less expensive with BA&D's plan.

To find the intersection point,
6+6g=10+4g

We cannot have a variable on both sides, so we will subtract 4g from both sides:
6+6g-4g=10+4g-4g
6+2g=10

Subtract 6 from both sides:
6+2g-6=10-6
2g=4

Divide both sides by 2:
2g/2 = 4/2
g = 2

This is the point where the plans cost the same. If we try a number smaller than 2 in both plans,
6+6(1) = 6+6 = 12
10+4(1) = 10+4 = 14

BA&D's plan is less.

In a certain game of dice, two fair dice are rolled. If the total of the faces is 4 or 10, you win. If the total is 2, 3, or 11,

goldenfox [79]

You answer should be 7/12, or aprox. 0.58 (I could be wrong)

You need to divid the number of outcomes that will satisfy your probability (anything that’s not 4,10,2,3, or 11, so there are 7 numbers left) by the total number of outcomes, (12), and that’s your answer
