Nataly [62]3 years ago
6 0

Step-by-step explanation:

Simply replace X with 3 etc...

f (x) = 4x + 7

f (3) = 4 (3) + 7

f (3) = 12 + 7

f (3) = 19

f (2x) = 4 (2x) + 7

f (2x) = 8x + 7

Answer:

For the first one after F(3), write 4x + 7

4x + 7 12 + 7 = 19

For the second one after F(2x) write 4x + 7

24 + 7 = 31

Step-by-step explanation:

I believe the number after the f represents the x, so you put that into the original equation

Find the midpoint of the line segment whose endpoints are (-2, 5) and (6, -9). (4, -4) (2, -2) (1, -4)
Rus_ich [418]

Answer:

(2,-2)

Step-by-step explanation:

The midpoint of the line segment with endpoints (x_1,y_1) and (x_2,y_2) has coordinates

\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

If the endpoints of the line segment are (-2,5) and (6,-9), then the midpoint has the coordinates

\left(\dfrac{-2+6}{2},\dfrac{5+(-9)}{2}\right)\\ \\\left(\dfrac{4}{2},\dfrac{-4}{2}\right)\\ \\(2,-2)

What is bigger 5/6 or 11/12?
Maurinko [17]
First you find the common deoninator.
Step 1: Reduce (simplify) entered fractions to lowest terms, if the case:Fraction: 5 / 6 it's already reduced to lowest terms
Fraction: 11 / 12 it's already reduced to lowest terms
Step 2: Calculate LCM (lowest common multiple) of the reduced fractions' denominators, it will be the common denominator of the compared fractions:Denominator 6, factored = 2 * 3
Denominator 12, factored = 22<span> * 3</span>
LCM (6, 12) = 22<span> * 3 = 12</span>Step 3: Calculate each fraction's expanding number (LCM divided by each fraction's denominator):For fraction: 5 / 6 is 12 : 6 = (22<span> * 3) : 6 = 2</span>
For fraction: 11 / 12 is 12 : 12 = (22<span> * 3) : 12 = 1</span>
Step 4: Expand fractions to bring them to the common denominator (LCM):5 / 6 = (2 * 5) / (2 * 6) = 10 / 12
<span>11 / 12 = (1 * 11) / (1 * 12) = 11 / 12</span>
