Evaluate the given expression when x = 3.

Enter the number only.

Answers

3^3 + 6*3+ 5
27 + 6*3 + 5
27+ 18 + 5
The answer is 50

Answer:

50

Step-by-step explanation:

If x=3 then x^3 would be 3 with the exponent of 3. It would look like 3x3x3=27

6x would be 6 times 3 which is 18.

Then you have just an extra 5.

Then add them all together. 27+18+5=50.

Therefore, your answer is 50.

Describe, step-by-step how to find the slope of a line through two points

Answers

Step One: Identify two points on the line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

Step Three: Use the slope equation to calculate slope.

The equation used to calculate the slope from two points is: m= y2 - y1 / x2 - x1

Example

Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?

Step One: Identify two points on the line.

In this example we are given two points, (15, 8) and (10, 7), on a straight line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).

Step Three: Use the equation to calculate slope.

Once we've completed step 2, we are ready to calculate the slope using the equation for a slope:

B. In the boys' long jump, Kevin jumped a distance of (6x1) + (9x 1/10) + (8x1/100)+(3x1/1000) meters. Leon jumped a distance of 6.093 meters. Kevin said he jumped farther than Leon. Is Kevin correct? Explain why or why not.

Answers

6*1 = 6

Next...

1/10 = 10% which equals 0.1
0.1 * 9 = 0.9

Now...

1/100 =1% which equals 0.01
So that means that 0.01 * 8 = 0.08

Lastly... 0.0010 * 3 = 0.003

You add
6 + 0.10 + 0.08 + 0.003 and you get 6.183.... (Kevin’s distance) which is obviously a farther distance than 6.093.

Kevin is correct :)

II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52

Answers

Answer:

Step-by-step explanation:

1. x+2y=6 or x=6-2y

3x-2y=2

3(6-2y)-2y=2

18-8y=2

-8y=-18+2

-8y=-16

y=-16/-8

y=2 ans.
