If f(x) = 3x - 1 and g(x) = x + 2, find (1-9)(x).
Studentka2010 [4]

Answer:

(f-g)(x)=2x-3

Step-by-step explanation:

<em>The correct question is</em>

If f(x)=3x-1 and g(x)=x+2, find (f-g)(x)

we know that

(f-g)(x) is equal to subtract the function g(x) from the function f(x)

so

(f-g)(x)=f(x)-g(x)

substitute the given functions

(f-g)(x)=(3x-1)-(x+2)

Remove the parenthesis

(f-g)(x)=3x-1-x-2)

Combine like terms

(f-g)(x)=2x-3

Makovka662 [10]

Answer:

Step-by-step explanation:

2. area of a triangle is 1/2 b h

1/2 (5 * 2) = 5 yd squared

area of the circle is pi r squared

you only need 1/2 of this area

find all these areas and add them together.

6. this is just a square sitting on a rectangle.

36 x 36 for the square

36 x 60 for the rectangle

add these together.

8. this a 1/2 circle and a triangle.

area of a circle is pi r squared

r is 7 in this problem

the area of a triangle is 1/2 b h

height is 7x2 here or 14

add the two together.

The shoe store expected to sell at least 95 pairs of shoes one weekend, but they only sold 77 pairs. What was the approximate pe
Gwar [14]
The error of percentage is the amount of error over the original amount.

In this case it is 22/95  (not 22 over 77 because 77 is not the original amount they expected to sell.   

22/95 = .2315  or 23.2% to the nearest tenth of a percent
Perhaps your teacher just wants 23% as an the approximate error.
