Find f(-10).

marysya [2.9K]

Answer: -75

Explanation: In this problem, we're given the function f(x) = 7x - 5 and we're asked to find f(-10).

To find f(-10) or the value of the function when x = -10 we simply substitute -10 in for x in our function.

So we have 7(-10) - 5 or -70 - 5 which equals -75.

So f(-10) or the value of the function when x = 10 is -75.

Since your answer to this problem was a, your answer is correct.

Anettt [7]

2x + 5x + 4 = 25
7x + 4 = 25
7x +4 (-4) = 25 (-4)
7x = 21
7x/7 = 21/7
x = 3

26 = 3b - 2 - 7b
26 = 4b - 2
26 + 2 = 4b - 2 (+2)
28/4 = 4b/4
b = 7

5m/8 - 6/8 +3m/8 = 2/8
8m/8 = 8/8
m = 1

The slope of the line below is - 1. Write a point-slope equation of the line

LiRa [457]

Answer:

$\large\boxed{y-3=-(x-3)}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

We have the slope m = -1 and the point (3, 3).

Substitute:

$y-3=-1(x-3)$

Paul bought a circular rug for his living room. The rug has a diameter of 11 feet. About how much of Paul's living room will be

fenix001 [56]

Answer:

The rug has covered approximately 95 square feet of the living room.

Step-by-step explanation:

Given:

Diameter of rug = 11 feet

We need to find the area covered in living room by the rug.

Solution:

Diameter of rug = 11 feet

Radius is half of the diameter.

Radius of the rug = $\frac{11}{2}=5.5\ ft$

Now it has been given that rug is in circular shape.

So we will find the area of the rug using Area of circle formula which is given by π times square of the radius.

Framing in equation form we get;

area of the rug = $\pi r^2 = 94.99\ ft^2 \approx 95\ ft^2$

Hence The rug has covered approximately 95 square feet of the living room.
