Your answer should only contain positive exponents

Answers

The answer is 8n. You can get this answer by multiplying the 4 and 2 first to get 8, then since the bases are the same (both bases are n) you can just add the exponents to get 1. Since n^1 is just n, the answer would be 8n

help me please i need to find out what the sum is and what the product is and the remaining qotient

Answers

Answer:

Quotient 5/6

Product 8b

Sum 5/6+8b

Step-by-step explanation:

Sum is addition and there is only one expression of the three that has addition. So sum goes with 5/6+8b.

Quotient is division or fraction so 5/6 is the expression to go with quotient.

Product is times so 8b is the expression that goes with that because 8b means 8 times b.

Answer:

Quotient 5/6

Product 8b

Sum 5/6+8b

For this linear equation, give the number by which you would multiply the terms in each equation in order to eliminate one of the variables. Then solve this system:
5x+2y=-1; 3x+7y=11

This would be a big help if you also include the process to help me understand the answer!

Answers

Answer:

Step-by-step explanation:

The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).

Answer:

Step-by-step explanation:

If we choose to eliminate x, multiply the first equation by -3:  -15x - 6y = 3

and multiply the second by 5:  -15x - 35y = 55

Note that this allows us to eliminate x.  We get:

-6y = 3

-35y = 55

which sum up to -41y = 58.  Thus, y = -58/4.

What additional information is required to prove the triangles are congruent using ASA?
Since vertical angles are congruent assume:

Answers

Answer:

C

Step-by-step explanation:

We already have one angle form the question that leaves us with one other angle and one side that we need to find, since we are required to use ASA or angle-side-angle.

the diagram gives us 2 congruent sides UB and AB since they have a similar slash on both of them, finally we need one more angle, so we look at the choices we have:

a) it gives us congruent sides not angles, so we move to the next

b) same thing as A

c) gives us 2 congruent angles, and since these are 2 new angles not given in the question, they can work

d) these 2 angels are the same 2 given in the question, so we can't use them.

Solve for x.
4 (x + 1 1/3) = 9 2/3
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 13/12

x = 1 1/12

Step-by-step:

4 (x + 1 1/3) = 9 2/3

4x + 5 1/3 = 9 2/3

subtract 5 1/3 from each side

4x = 4 1/3

divided by 4 on each side

x = 13/12

x = 1 1/2

X = 1 1/4

Drag each angle measure to the correct location on the image. Each angle measure can be used more than once.

In the figure, two parallel lines are cut by two other parallel lines. The measures of one of the angles is labeled. Find the measures of the other angles and label them.

137° 52° 128° 38°

*then it’s the picture*

Answers

Answer:

In front of the 52, it'll be 52°, that's all I know.

Vertical angles are always congruent. Since the lines are parallel, we can use the Alternate Interior Angle Theorem.

The way I got 128 was by using the fact that the angles would add up to 360 and the Vertical Angle Congruence Theorem. Basically, the formula is x + x + y + y = 360°. If you replace x with 52°, we can deduce that y is equal to 360 - (52 + 52)/2. That gives us 128°.

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito.

Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.

How much profit would the restaurant make by selling 100 burritos?

1. How much money would the restaurant take in by selling 100 burritos?

2. What is the cost of making one burrito? (remember that costs are negative)

3. What is the cost of making 100 burritos?

4 What is the profit the restaurant makes from selling 100 burritos? Does the restaurant make money or lose money?

Answers

First let's find the cost to make the burritos.

$1.50 + $1.00 = $2.50 needed to make one burrito.

1. To find how much money the restaurant takes in from selling 100 burritos, we can do 100*8.00 which is $800.

2. We have already found the cost of making a burrito, which is $2.50

It says to convert the cost to a negative so I guess it would be -2.50?

3. The cost of making 100 burritos can be found by doing 100*2.50 which is equal to $250. The cost of making 100 burritos is $250.

4. To find the profit, we can subtract the answers from question 1 and question 3. 800-250 would be a profit of $550. The restaurant is gaining money. The price to make the burritos is way less than the money made from selling the burritos.

1. 550 becuase they make a 8 dollar profit, but then they lose 2.5 because to make the burito, they need to buy 1.5 dollars of meat and 1 dollar of ingredient. you get 8-2.5=5.5
then 5.5 times 100 because 5.5 is the amount gain after one burito. you want to find 100 so 5.5 times 100=550
2.-2.5
3.-2.5 times 100=-250
4. resturant makes money, they earn an 550 as said in the first question

Hello there!

Linear functions have a continuous pattern in their x and y values.

Let's see the first table.

0, 1, 2, 3

We add 1 every time.

-3, -2, 0, 3

We add 1, add 2, add 3.

That's not a linear function, because it doesn't have a continuous pattern in its y values.

Let's look at the next table.

0, 1, 2, 3

We add 1 every time.

1, 4, 3, 7

We add 3, subtract 1, add 3

That's not a linear function as well.

Now, let's look at the third table:

0, 1, 2, 3

We still add 1.

2, 0, -2, -4

We subtract 2 every time.

So this is a linear function. Hope this helps!
