If f(x) = 5x – 3 and g(x) = 3x – 3, find f(x) – g(x). Please include full explanation
Kisachek [45]

Answer:

2x

Step-by-step explanation:

f(x) – g(x)

f(x) = 5x – 3 and g(x) = 3x – 3

f(x)- g(x) = 5x – 3 -( 3x – 3)

Distribute the minus sign

               5x -3 -3x+3

Combine like terms

              5x-3x-3+3

               2x

The length of a rectangle is 2 units shorter than one-fifth of the width, x.
sergey [27]

Answer:

C. P=\frac{12x}{5} + 4

Step-by-step explanation:

Width = x

Length = one fifth of width minus 2

Length = \frac{1}{5}x-2

Perimeter is given by the formula

P=2(l+b)

P=2(\frac{1}{5}x-2+x)

P=2(\frac{x}{5}-2+x)

P=2\times \frac{x-2 \times 5+5 \times x}{5}

P=2\times \frac{x-10+5x}{5}

P=2\times \frac{6x}{5} - 2\times \frac{-10}{5}

P=2\times \frac{6x}{5} + 2\times \frac{10}{5}

P=\frac{12x}{5} + 4

What is the value of x, given the following system of linear equations? x + y = 8 and x - y = 2
zaharov [31]

Answer:

x = 5

Step-by-step explanation:

x + y = 8 \\ x - y = 2 \\ x + y + (x  - y) = 8 + 2 \\ x + y + x - y = 10 \\ 2x = 10 \\  \frac{2x}{2}  =  \frac{10}{2}  \\ x = 5 \\  \\ x + y = 8 \\ 5 + y = 8 \\ y =  8- 5 \\ y = 3 \\  \\ x - y = 2 \\ 5 - 3 = 2 \\ 2 = 2
