Answer:

66

Step-by-step explanation:

The mean is the average, to find you add all the numbers up and then divide by the amount of numbers you added.

66+73+65+60 = 264

264 : 4 = 66

I hope this helps :0)

Answer:

i cannot see the picture

Step-by-step explanation:

Answer:

yeah i definitely cant see the picture too

Answer:

No

Step-by-step explanation:

if you mean that:

[tex]m_{1} = \frac{4}{3}[/tex]

[tex]m_{2} = \frac{3}{4}[/tex]

And ask if m1 is parallel to m2. Then no.

Two lines are only parallel if their slopes are the same.

And since 4/3 is not equal to 3/4. Then the lines are not parallel.

Hope i could help you understand!

Answer:

New height = 11/2 ft

New height = 5 + 1/2(N)

Step-by-step explanation:

Given:

Initial height = 5 ft

Grown height = 1/2 ft

Find:

New height

Computation:

New height = Initial height + Grown height

New height = 5 + 1/2

New height = 11/2 ft

Equation;

New height = 5 + 1/2(Number of year)

New height = 5 + 1/2(N)

Answer:

b is 125

Step-by-step explanation:

Answer:

Step-by-step explanation:

Well, the formula to find slope is y2-y1 / x2-x1

Here's an example:

(2,12) (4,24)

12-24 / 2-4 =

-12/-2 or 6

You would use:

(y=mx+b) to find an entire equation, including the y intercept

Let me know if this helps, and if it doesn't, I hope I'll be able to explain it better.

Answer:

9.1

Step-by-step explanation:

Let,

hypotenuse = 12.3 cm

perpendicular = 8.2 cm

base = y cm

(hypotenuse)^2 = (perpendicular)^2 + (base)^2

(12.3)^2 = (8.2)^2 + y^2

151.29 = 67.24 + y^2

151.29 - 67.24 = y^2

.: y^2 = 84.05

y = √84.05

y = 9.1

Answer:

Mother's age is 35 while the daughter's age is 15

Step-by-step explanation:

If 5 years ago the mother was 3 times older and 10x3=30 then the mother was 30 and the daughter was 10, add 5 to both the numbers and you have your answer.

Answer:

6 and 10...

Make of you will of that.

Answer:

2/5

Step-by-step explanation:

The y-intercept is the number being added or subtracted in the equation when you have y = mx + b. For example, in the equation y = 9x - 4, the y-intercept is -4, and in the equation y = 3x + 7, the y-intercept is 7. The number being added in this case is 2/5, so it is the y-intercept.

Answer:

Y=-1+10/3x

Step-by-step explanation:

The slope is 10/3x and the point is -1. I think this is correct, but I’m not sure

Answer:

y=10/3

Step-by-step explanation:

10x-3y=3

Answer:

Before anyone gives anyone money, Mario has 24 dollars and Roberto has 12 dollars. After they give each other money, both of them have 18 dollars.

Step-by-step explanation:

Mario has twice as much as Roberto, BUT if Mario gives Roberto 6 dollars, then they have the same amount.

M = 2R

M - 6 = R + 6

To isolate M, you need to add 6 on both sides.

M - 6 + 6 = R + 6 + 6

M = R + 12

M = 2R

Substitute M for the value above that we found.

R + 12 = 2R

Now we subtract R on both sides, so that only one side has the variable R.

R - R + 12 = 2R - R

12 = R

M = 2R

Substitute for the value of R.

M = 2 x 12

M = 24

[tex]y-y_1=m(x-x_1)[/tex]

Given the x1 and y1 = given point.

Substitution x1 = 2 and y1 = -8 in the equation.

[tex] \begin{cases} x_1 = 2 \\ y_1 = - 8 \end{cases} \\ y - ( - 8) = - 4(x - 2) \\ y + 8 = - 4(x - 2)[/tex]

Hence, the solution is C choice.

[tex]y + 8 = - 4(x - 2)[/tex]

Answer:

x = 14

y = 22

Step-by-step explanation:

y = x + 8

4x - 2y = -12

Solve

_____________

Since we see that the first equation has y alone, we can substitute it into the values of y in the second equation.

4x - 2(x + 8) = -12

Distribute :

4x - (2(x) + 2(8)) = -12

4x - 2x +16 = -12

Combine like terms :

2x + 16 = -12

Subtract 16 from both sides :

2x = -28

Divide 2 from both sides to get x alone :

x = 14

Now that we know what x is, substitute it in the first equation to get y :

y = (14) + 8

y = 22

Answer:

(2 , 10) or x = 2 & y = 10

Step-by-step explanation:

y = x + 8

4x – 2y = -12​

1. Substitute x + 8 in for the y in the other equation.

2. Solve for x

3. Take the solution for x and substitute the number in for the x in y = x + 8.

4. Solve for y.

5. Your answer is the result.

4x - 2(x + 8) = -12                       Distributive Property

4x - 2x - 16 = -12                        Combine like terms

2x - 16 = -12                               Isolate the x, so start by moving -16

    + 16   +16                              

2x + 0 = 4                                  Delete the 0. It is a place holder you don't need

      2x = 4                                 Isolate the x by dividing both terms by 2.

        2    2

        x = 2

y = x + 8                      Substitute the 2 in for x and solve the one step equation.

y = 2 + 8

y = 10
