what is X and Z?

Answers

Answer:

X = -5Z + 31

Step-by-step explanation:

Subtract 5Z5Z from both sides.

19 - 5Z = X - 12

19 − 5Z = X − 12

2 Add 1212 to both sides.

19 - 5Z + 12= X

19 − 5Z + 12= X

3 Simplify  19-5Z+1219−5Z+12  to  -5Z+31−5Z+31.

-5Z + 31 = X

−5Z + 31 = X

4 Switch sides.

X = -5Z + 31

X = −5Z + 31

Answer:

19=x+5*z-12

19+12=x+5*z

31=x+5*z

then x=26 z=1

what is the slope on an equation

Answers

Answer:

Formula

Slope of a line

Once your equation is in slope-intercept form: "y = mx+b", the coefficient of "x" (the "m") is the slope. The constant (the "b") is the y-intercept at (0, b).

Step-by-step explanation:

slope= dy/dx

=y2-y1/x2-x1

Step-by-step explanation:

Done the first two but i dont know how to do the mean of it

Answers

I think the answer for the mean is 6.

To get the mean you have to add up the total number of peas in a pod, then divide the amount you added up by how many pods there are. :)

To find mean:

1) Add up all data values to get the sum

2) Count the number of values in your data set

3) Divide the sum by the count

First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.

4 x 2 = 8

5 x 10 = 50

6 x 18 = 108

7 x 14 = 98

8 x 6 = 48

8 + 50 + 108 + 98 + 48 = 312 total number of peas

2 + 10 + 18 + 14 + 6 = 50

312 / 50 = 6.24 peas per pod

So in our example the mean number of peas in a pod is 6.24.

I hope this helps! :)

which expression has a value of 6 when x=2 and y=4?

Answers

B
refer to picture for steps
Answer:6Verification:

Let's verify all the options to the question. Clue given: x = 2, y = 4

Option A:

(x² + 8) ÷ y - 2

=> (2² + 8) ÷ 4 - 2

=> (4 + 8) ÷ 4 - 2

=> 12 ÷ 4 - 2

=> 3 - 2

=> 1 ≠ 6

This answer does not equal 6.

Option B:

(x² + 8) ÷ (y - 2)

=> (2² + 8) ÷ (4 - 2)

=> (4 + 8) ÷ (4 - 2)

=> 12 ÷ 2

=> 6 = 6

This answer is correct as 6 = 6.

Option C:

x² + 8 ÷ (y - 2)

=> 2² + 8 ÷ (4 - 2)

=> 4 + 8 ÷ 2

=> 4 + 4

=> 8 ≠ 6

This answer does not equal 6.

Option D:

x² + 8 ÷ y - 2

=> 4 + 8 ÷ 4 - 2

=> 4 + 2 - 2

=> 4 ≠ 6

This answer does not equal 6.

So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

2x - 8x + 1 = 49
this seriously makes no sense

Answers

Answer:

x = -8

Step-by-step explanation:

2x - 8x + 1 = 49

⇒ 2x - 8x = 49 - 1

⇒ -6x = 48

⇒ x = [tex]\frac{48}{-6}[/tex]

       = -8

Answer:

X = -8

Step-by-step explanation:

Add similar elements: 2x-8=6x

-6x+1=49

Subtract 1 from both sides:

-6x+1 -1 =49 - 1

Simplify:

-6x=48

Divide both sides by -6

-6x /-6= 48 /6
