harkovskaia [24]
Ahh..this is sets topics - A U B = all the elements found in A and B. But do note, do not repeat the elements if it is the same. And if the question were to ask : n(AUB) = total number of elements found in A and B.

Which function has an inverse that is a function?
shusha [124]

Answer:

  C.  -7x

Step-by-step explanation:

Only one of the offered choices passes the horizontal line test: at most one point of intersection with any horizontal line.

__

A: a parabola opening upward, so will have two points of intersection with a general horizontal line (only one at the vertex).

B: a horizontal line, so will have an infinite number of points of intersection with a horizontal line.

D. A "V-shaped" graph that will generally have two points of intersection with a horizontal line (only one at the vertex).

HELP AND EXPLAIN PLSS
balu736 [363]

Answer:

Amount they ate is 6/8 or 3/4 of the pizza

Amount left over is 2/8 or 1/4 of the pizza.

Step-by-step explanation:

your family at 6 out of 8 pieces and simplified thats 3/4 if you divide both by 2

so the pieces left over would be 2 pieces or 2 out of the 8 pieces are left over.

making your fraction 2/8

Now you simplify and you can divided both 2 and 8 by 2

Making your other fraction 1/4

Please Help! i need explanations too. Thank you

Answer:

Step-by-step explanation:

The most important thing to remember when solving equations is whatever you do to one side, you must do to the other.

1. (15m + 3)/2 = -6

First, we can simplify by removing the fraction:

15m + 3 = -6 x 2 (multiply both sides by 2)

15m + 3 = -12

15m = -12 - 3 (subtract by 3 on both sides)

15m = -15

m = -15/15 (divide by 15 on both sides)

m = -1

2. 3/2x -15 = -12

first, we'll add both sides by 15

2/3x = -12 + 15

2/3x = 3

x = 3/(2/3) both sides divided by 2/3, just put that in your calculator, if you can't do it in your head

x = 4 1/2

3. -7x + 3 = -15/2

We can remove the fraction by doing the same thing as in the first question.

2(-7x + 3) = -15

-14x + 6 = -15

14x = -15 -6

14x = -21

x = -21/14

x = -1 1/2

4. 4x + 1/2(12x + 2) = 3

First we need to simplify by expanding:

4x + 6x + 1 = 3

Now we collect the like terms to further simplify the equation

10x + 1 = 3

10x = 3 - 1

10x = 2

x = 2/10

x = 1/5

5. 3/2(x + 8) = 6x

We're going to start by removing the brackets, this time by multiplying the fraction on both sides:

x + 8 = 6x / (3/2)

x + 8 = 4

x = 4 - 8

x = -4

Now the questions, some of them are personal, so I won't be able to answer them for you, but I can try with the others:

These types of problems are fractional equations, and you need to find the value of the variable, which in this case was x.

I'm not sure what information you already know, so you'll have to think on that one.

Strategies you could use or try include multiplying, dividing, subtracting and adding on both sides as well as collecting like terms and expanding.

Hope this helped,

Cate

What is the probability of getting heads when flipping a coin and getting a number greater than or equal to 3 when rolling a sin
nikklg [1K]
Not 100% sure on this but i believe it is C 1/12. it is 1/2 for heads and tails and 1/6 for rolling a die. multiplying 1/2 by 1/6 gets you 1/12 so i think it is probably C.
