F(x)=|3x+5|+6 g(x)=7 find (f+g) (x).

horrorfan [7]

Answer:

$(f+g) (x)=\mid 3x+5\mid+13$

Step-by-step explanation:

Operation of Functions

Given:

$f(x)=\mid 3x+5\mid+6$

$g(x)=7$

The sum of (f+g) (x) is:

$(f+g) (x)=\mid 3x+5\mid+6+7$

We cannot operate with the expression inside the absolute bars, thus:

$\boxed{(f+g) (x)=\mid 3x+5\mid+13}$

2/5- -3/4 what would be the answer?

Ipatiy [6.2K]

For this case we must simplify the following expression:

$\frac {2} {5} - (- \frac {3} {4})$

By definition of the law of multiplication signs we have to:

$- * - = +$

So, rewriting the expression we have:

$\frac {2} {5} + \frac {3} {4} =\\\frac {4 * 2 + 5 * 3} {5 * 4} =\\\frac {8 + 15} {20} =\\\frac {23} {20} = 1.15$

Thus, the answer in decimal form is 1.15.

Answer:

$\frac {23} {20} = 1.15$
