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

Find (f-g)(x), this means we need to subtract g from x.

(3x-1) - (x+2)

Subtract the like terms:

3x -x = 2x

-1 -2 = -3

Combine them to get 2x-3

The answer is A.

Answer:

Option A.

Step-by-step explanation:

The given functions are

f(x)=3x-1

g(x)=x+2

we need to find the function (f-g)(x).

Using the composition of functions the subtraction of two functions is defined as

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

Substitute the given values of functions f(x) and g(x).

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

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

On combining line terms we get

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

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

Therefore, the correct option is A.

If the area of a square with side x is equal to the area of a triangle with base x, then find the altitude of the triangle.
zhannawk [14.2K]

Answer:

h= 2x

Step-by-step explanation:

Given

Square

Side = x

Triangle

Base = x

Altitude = h

Required

Find h, if both shapes have the same area

The area of the square is:

Area = x * x

Area = x^2

The area of the triangle is:

Area = \frac{1}{2} * Base*Height

Area = \frac{1}{2} * x*h

Equate both areas

x^2 = \frac{1}{2} * x*h

Divide both sides by x

x = \frac{1}{2} *h

Multiply both sides by 2

2*x = \frac{1}{2} *h*2

2x = h

h= 2x

(a) Tom says that 1/5 + 7/20 = 8/25
mezya [45]

numerator = top part of the fraction

denominator = bottom part of the fraction

* means multiply

a.

you can only add the numerator when the denominator is the same

cant add the denominator

denominator has to be the same

1/5 = 4/20

4/20 + 7/20 = 11/20

b.

1 7/8 = 15/8

3/4 ÷ 15/8 =

3/4 * 8/15 =

24/60 = divide both top and bottom by 12 =

2/5

two sides of a triangle measures 20 centimeters and 30 centimeters which of the following could be the measure of the third side
brilliants [131]
To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2.  First answer, 20^2+30^2=c^2.  Solve for c.  c=36.06.  The second answer, 20^2+b^2=30^2.  Solve for b.  b=26.36.
