Find the slope of the line that passes through (13, 7) and (13, 11).​

Answers

Answer:

there's no slope.

Step-by-step explanation:

m = (11 - 7) ÷ (13-13)

m = 4 ÷ 0

m = undefined, since you cannot divide by 0

Answer:

undefined since they have the same x value

Step-by-step explanation:

if you plot these 2 points on a graph you'll see that they are vertical, I remember that if they are like this then they have an undefined slope, if they have the same y value they will be flat or a slope of 0.

Step-by-step explanation:

Hello There!

If you didn't know vertical angles are congruent

That being said we can use this equation to solve for x

40 = 5x

Objective: Isolate the variable using inverse operations

To get rid of the 5 we divide each side by 5

40 / 5= 8

5x/5=x

we're left with x=8

To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct

5(8) = 40

So the answer would be 8

Answer:

8

Step-by-step explanation:

40÷5=8

Answer:

I believe the answer is 8m.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) Perimeter = 2m + 3m +3m + 2 + 2m + 2

                =  2m + 3m + 3m + 2m + 2 + 2         {Combine like terms}

                = 10m + 4

2) 10m = 2 * 5 * m

    4    = 2 * 2

GCF = 2

10m + 4 = 2 *5m + 2*2

             = 2*(5m + 2)

Answers

Answer:

600

Step-by-step explanation:

so basically all you have to do make the fractions equal. if 6 is equal to 10 then 600 is equal to 1000

600/1,000.

I believe the way you solve this problem is with multiplication.

Every time you multiply something by 10 you simply add a zero. The same goes for 100, you just simply add two zeros.

Since this is a fraction, you do the same for the numerator.

10 times 100 is 1,000 and 6 times 100 is 600. 600/1,000.

If this is incorrect, please, don't refrain to tell me.
