Simplify the expression ​

Mathematics
1 answer:
finlep [7]3 years ago
3 0

Answer:

\frac{2*x - 2}{2*x}  - \frac{3*x + 2}{4*x} = \frac{x - 6}{4*x}

Step-by-step explanation:

We have the expression:

\frac{2*x - 2}{2*x}  - \frac{3*x + 2}{4*x}

The first thing we want to do, is to have the same denominator in both equations, then we need to multiply the first term by (2/2), so the denominator becomes 4*x

We will get:

(\frac{2}{2} )\frac{2*x - 2}{2*x}  - \frac{3*x + 2}{4*x} = \frac{4*x - 4}{4*x}  - \frac{3*x + 2}{4*x}

Now we can directly add the terms to get:

\frac{4*x - 4}{4*x}  - \frac{3*x + 2}{4*x} = \frac{4*x - 4 - 3*x - 2}{4*x}  = \frac{x - 6}{4*x}

We can't simplify this anymore

1. For the function f(x) = 5, determine each of the following values.
Bess [88]

Answer:

f(4) = 5

Step-by-step explanation:

f(x) = 5.

Whatever value of x you input to the function , the function's value is always 5.

This is seen when you examine the graph of f(x) = 5. It is a straight horizontal line passing through y = 5. For every value of x along the line, f(x) = y = 5.

Aleksandr [31]

Answer:

1000 x .15 = 150 The car will lose 15% value after the first year which is $150. Subtract 150 from 1000 and the new value would be $850.

5020 x .15 = 753 This car lost 15% after the first year which is $753. Subtract 753 from 5020 and the new value would be $4287.

2. Given f(x) = 6(8 - x)+5
son4ous [18]

Answer:

a) Find the value of the function when x  = -2

b) we get f(-2)=65

Step-by-step explanation:

We are given the function f(x)=6(8-x)+5

a) What does the notation f(-2) mean?

The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x  = -2

b) What is the value of f(-2) ?

We need to find the value of f(-2)

f(x)=6(8-x)+5

Put x = -2

f(-2)=6(8-(-2))+5\\f(-2)=6(8+2)+5\\f(-2)=6(10)+5\\f(-2)=60+5\\f(-2)=65

So, we get f(-2)=65
