Answer:

40

Step-by-step explanation:

Remark

The catch is that all of the sides given are radii of a circle (the circumcircle in this case.)

Take and two given lines. Equate them. Solve for x. Then go back and substitute x for RC.

Equation

PC = RC

3x + 7 = 5x - 15

Solution

3x + 7 = 5x - 15                   Add 15 to both sides

3x + 7 + 15 = 5x - 15 + 15    Combine like terms

3x + 22 = 5x                        Subtract 3x from both sides

3x - 3x + 22 = 5x - 3x         Combine like terms.

22 = 2x                                Switch and divide by 2

2x/2 = 22/2                         Solve

x = 11

Answer

RC = 5x - 15

RC = 5*11 - 15

RC = 55 - 15

RC = 40

Answer:

Required ordered pair is (0,0) for system of equation

Step-by-step explanation:

The given system of equation is

A). 9^{12x} = 9^{3y}

B). y^{4} - 9y^{2} x^{2} =16y

On simplifying the equation A

9^{12x} = 9^{3y}

Take log on both side,

(12x) (log9) = (3y) (log9)

4x=y

To find the solution of the system of the equation :

Replacing value of y=4x in equation B,

y^{4} - 9y^{2} x^{2} =16y

(4x)^{4} - 9(4x)^{2} x^{2} =16(4x)

256x^{4} - 144x^{2} x^{2} =64x

256x^{4} - 144x^{4}=64x

112x^{4}=64x

We get,

x=0 and x=0.829

Since, 0.829 is not integer number

Only solution of equations is x=0

For the value of y

Replace value x in y=4x=0

Thus, Required ordered pair is (0,0)

Working together, 5 friends collected 15 5/8 bags of food for the homeless. On average, how many bags of food did each friend co
Effectus [21]

15 5/8 divided by 5

First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8

125/8 divided by 5/1 (which is equal to 5)

Next, we do Keep Change Flip.

Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.

1 * 125 = 125

8 * 5 = 40

Then, we get 125/40 = 3 5/40 BUT WAIT

We can reduce it once more! Divide 40 by 5

Each friend collected 3 1/8 bags of food.

Use the graph below to fill in the blank with the correct number:<br><br> f(0) = (1 point)
Lelechka [254]

From the graph,

f(0) = 1

Notice that when x = 0, y = 1.

If we plot the point (0,1) It's the same point. So f(0) = 1 is basically substituting x = 0 and get y = 1
