Answer 1

Answer:

The answer is supposed to be -9, not 9.

Step-by-step explanation:

In step 2, when you are adding a negative plus a negative (-4 + -5) it should always come out a negative. So, step 3 should come out as -9 instead of 9.

Solve this linear equation using substitution. (Please show work!)

y = -x
y= 3x - 4

Answers

Answer:Under↓↓↓

Step-by-step explanation:

-x=3x-4 (substitute -x for y)

-4x=-4 (Subtract 3x from both sides)

x=1 (Divide both sides by -4)

Since y=x then y=1

Answer:

X=1

Step-by-step explanation:

So if you look at the two y= equations, you'll see that you can make them equal two one another because they both equal y

Placing the -x in place of y for it to look like this; -x = 3x-4. Subtract the 3x to the other side to get -4x =-4. Then divide the 4 from the x to isolate it and you get x=1!

Hope that helps!

What is the y-intercept of the function below?
2x - 3y = 12

Answers

Answer:

The slope is −23

Step-by-step explanation:

You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

(0,-4) is the y-intercept

Explain how to compare two fractions that have the same numerator and different denominators. Use an example to help justify your response.

Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate..

Answers

Answer:

Step-by-step explanation:

2 fractions with the numerator and different denominators can be compared when you find the lowest common denominators (LCD. For example 1/2 and 1/3 have the same numerator, but the denominators are not so you have to find the LCD. The LCD, in this case, is 6, so the fractions would be 3/6 and 2/6 and now if you compare you can tell that 3/6 is greater than 2/6 so 1/2 is greater than 1/3.

Answer:

Answer is down below :D

Step-by-step explanation:

A numertator is the top number and the denominators are the bottom number of a fraction. You can tell the difference because if you look at the top number of one fraction and you look at the other that you're supposed to compare and there the same number, then they are the same. For example, 1/2 and 1/3 have the same numetators but not denominators. Now for denominators you have to look at the bottom number but if the two fractions you're comparing have the same bottom number then there the same, but if they have two different bottom numbers, then they are not the same. For example again: 1/3 and 1/9 The may seem the same but there not since the bottom number is different.

Of 630 seats in the cafeteria, 70% are in use. How many seats are being used?

Answers

Answer:

70

Step-by-step explanation:

630 divided by 70 is 9, so then you take 630 again and divide it by 9 to get 70

The answer would be 441 seats are being used.

I know this because if you set up the equation as a fraction you will get:

x/630 and 70/100

if you multiply 630 by 70 you get 44100,
but you then take the 100 and divide 44100 by 100 and you get 441 using the cross multiply method.

2,000 divided 20 =
what is the answer i need it

Answers

Answer:

Step-by-step explanation:

Cross out one zero on both sides, which would change the equation to 200/2=100

The answer to 2,000 divided by 20 is 100.

Division is the inverse operation of multiplication, so dividing a number by another is the same as finding the number of times the divisor can fit into the dividend.

When divide 2,000 by 20, essentially finding out how many times 20 fits into 2,000.

Since 20 goes into 2,000 exactly 100 times as:

20 x 100 = 2,000, that is the result is 100.

In this case, 20 fits into 2,000 precisely 100 times, resulting in a quotient of 100.

11PTS can anyone help me with these 2 questions.​

Answers

Answer:

N.14: No Solution for both N.15: x=17, LP=34, and LN=34

Step-by-step explanation:

N.14:

2x+12=2x-64 (subtract 2x from both sides)

12=-64

Therefore No Solution Because 12 doesn't equal -64

N.15:

4x-34=2x (subtract 4x from both sides)

-2x=-34 (Divide both sides by -2)

x=17

LP=4(17)-34 (Substitute x for 17)

LP=68-34

LP=34

LN=2(17) (Substitute x for 17)

LN=34
