how can you simplify integer expressions that contain more than one operation?
answer quick pls

Answers

Answer 1

Evaluate in the order of operations! PEMDAS

Parentheses

Exponents

Multiply/Divide (left to right)

Addition/Subtraction (left to right)

Example: 5 x 2 / 5 + (6 x 3)

1. Evaluate parentheses: 6 x 3 = 18

2. Multiply and divide: 5 x 2 = 10, 10 / 5 = 2

3. Add and subtract: 2 + 18 = 20

4. We're done: 20

Answer:  

A line has a slope of zero. Which of the following points could this line pass through?

(3, -6) and (7, -6)

(-8, 6) and (8, -6)

(12, 9) and (12, 6)

(3, 4) and (4, 6)

(-8, 6) and (8, -6)

(12, 9) and (12, 6)

(3, 4) and (4, 6)

Step-by-step explanation:

The answer would be (3,-6) and (7,-6) because if the slope is zero it wouldn't go any where it would stay the same, and I'm pretty sure it would be negative.

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
Options:
m = 4 Point = (1/3, 1)

m = 1/3 Point = (1, -4)

m = 1/3 Point = (1, 4)

m = 1/3 Point = (-1, 4)

Answers

Answer:

m = 1/3 Point = (1, -4)

The slope is 1/3.

The point is 1,-4.

If you are wondering how I got the point, I just unsimplified the equation!

From y+4=1/3(x-1).

To y- -4=1/3(x-1).


The original formula is y-y1=m(x-x1). So we know where the y and the x is, and the slope.

Hope this helped!! :)

Answers

Answer:

All Real Numbers

Step-by-step explanation:

First, use the distributive property to expand everything:

8v-6=10v-6-2v

Then, combine like terms:

8v-6=8v-6

Then, subtract 8v from both sides to isolate the variable:

0-6=-6

-6=-6

Any real number you substitute with v will make the equation always true, as -6 always is equal to -6. Therefore, the answer is All Real Numbers.

Alll that equals -6 hope this helps

5. Using the equation y=2x+5, construct a table and graph the line

Answers

Step-by-step explanation:

What you are going to do is for each value of x (which is the value to the right on the table) you will find the Y value.

So for X = 0

y = 2(0)+5 = 5

x = 1

y = 2(1)+5 = 7

x = 3

y = 2(3)+5 = 11

x = 5

y = 2(5)+5 = 15

x = 10

y = 2(10)+5 = 25

Now for what you do is place the correspanding value into the graph.

(x,y) = (0,5), (1,7), (3,11),(5,15),(10,25)

What is 5x-y=1/4 in slope intercept form? PLEASE give me step by step explanation and why you did what. Thank you! ❤

Answers

Answer:

y=5x-1/4

Step-by-step explanation:

The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.

Answer:

The calculation to your equation is:

Y=5x-1/4

Even if it depends on the x, the constant of proportionality just goes by the multiple of 2 as you can see on the graph.

Answer:

Melinda saves 2 less dollars than Marcus each week.

Step-by-step explanation:

Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.

14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.

Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.

When REM sleep begins, Signals move to and from different regions of the brain. Some signals are sentto the brain's cerebral cortex, which is responsible for learning, thinking, and organizing information. Signals arealso sent to the spinal cord to shut off movement, which produces a temporary paralysis in the arms and legs. Thisparalysis creates an opportunity for true rest to take place in the body. The regions of the brain that are stimulatedduring REM sleep are responsible for learning.
