Answer:

x = 33/3 = 11

Step-by-step explanation:

A and B are corresponding angles and are therefore equal.

Thus, A = 8x - 8 = B = 5x + 25, or

3x = 33

and so x = 33/3 = 11

If f(x)=-8-5x, what is f(-4) (If possible, explain your answer)

timofeeve [1]

<span> f(-4) all you need to do is plug in x = -4 into equation
so </span><span>If f(x)=-8-5x then
f(-4) = -8 - 5(-4)
f(-4) = -8 + 20
f(-4) = 12

answer
f(-4) = 12</span>

One number is 2/5 of another number. the sum of the two numbers is 35. find the two numbers. use a comma to separate your answer

Ivan

We have x = (2/5)y and x + y = 35;
then, (2/5)y + y = 35;
2y + 5y = 175;
7y = 175;
y = 27;
x = 35 - 27;
x = 8;

What's the mean median and range of 5, 15, 10, 20,15 10, 15

Korvikt [17]

Answer:

Mean = 12.85714

Median = 15

Range = 15

Step-by-step explanation:

Mean:

5 + 15 + 10 + 20 + 15 + 10 + 15 = 90

90 / 7 = 12.85714

Median:

5, 10, 10, 15, 15, 15, 20

Median = 15

Range:

20 - 5 = 15

The endpoints of a diameter of a circle are A(3,1) and B(9,9). Find the area of the circle in terms of pie

andrey2020 [161]

Answer:

The answer is $25\pi$ units squared.

Step-by-step explanation:

If we find the diameter, we can find the radius by halving the diameter.

We can find the diameter by using the endpoints of the diameter.

The distance formula will give us the length between (3,1) and (9,9).

The distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

The distance between the $x$ 's is 9-3=6.

The distance between the $y$ 's is 9-1=8.

The distance between the points is given by $\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10$ .

The radius is therefore $\frac{10}{2}=5$ .

We are asked to find the area of this circle.

The formula for finding the area of a circle is $\pi r^2$ .

Since the radius is $5$ , then the area in terms of $\pi$ ,(pi), is $\pi (5)^2=\pi (25)$ .

The answer is $25\pi$ units squared.
