13. simplify this expression: ) - (-14) = ?

19-(-8)-(-14) = 41

Step-by-step explanation:

First, we have to solve what is in parentheses

by law of signs ( - . - = +)

19 + 8 + 14 = ?

Then, we only have to sum the number to obtain the result

19 + 8 + 14 = 41

41

Step-by-step explanation:

We must do multiplication before addition or subtraction here.

-(-8) = +8 and -(-14) = +14, and therefore:

19 - (-8) - (-14) becomes 19 + 8 + 14, or 19 + 22, or 41.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
