1 answer:

5 0

5a + 2a(5 + (-b)) = 5a + 2a(5 - b)

Use the distributive property which states a(b+c) = ab + ac

5a + 10a - 2ab

Simplify like terms

15a - 2ab

What is the sum of the rational expressions below? X/4 + 3/5x

Andrew [12]

Answer:

The answer is $\frac{5x^2+12}{20x}$ .

Step-by-step explanation:

Given:

X/4 + 3/5x.

Now, to find the sum of the rational expressions.

$\frac{x}{4} +\frac{3}{5x}$

So, to solve it by adding:

$\frac{x}{4} +\frac{3}{5x}$

$=\frac{5x\times x+3\times 4}{5x(4)}$

$=\frac{5x^2+12}{20x}$

Therefore, the answer is $\frac{5x^2+12}{20x}$ .

Compare the graphs below of the logarithmic functions. Write the equation to represent g(x).

Neporo4naja [7]

Answer:

The equation to represent g(x) will be $g(x)=log(x)+4$

Step-by-step explanation:

Considering the logarithmic function

$f(x)=log(x)$

As we know that when a constant c gets added to the parent function, the result would be a vertical shift c units in the direction of the sign of c.

So,

$g(x)=log(x)+4$ is basically the shift up by 4 units, and the graph also showing the same situation.

Therefore, the equation to represent g(x) will be $g(x)=log(x)+4$

Also, the graphs of both $f(x)=log(x)$ and $g(x)=log(x)+4$ is attached where black mark graph represents $f(x)=log(x)$ and red mark graph represents $g(x)=log(x)+4$ .
