I need help!!!! <br> Which represents the inverse of the function f(x)=4x?
Mrac [35]

Answer:

h(x)=\frac{1}{4}x.

Step-by-step explanation:

The inverse is basically you just swapping x and y.  People want to solve it for y to make it a function of x.

y=4x

Swap x and y:

x=4y

Now solve for y by dividing y on both sides:

\frac{x}{4}=y

\frac{1}{4}x=y

y=\frac{1}{4}x.

Given the expression -15 (10 2/3) A. Rewrite the expression using distributive property B. Evaluate the expression in show all y
Ainat [17]

9514 1404 393

Answer:

  -160

Step-by-step explanation:

  -15(10 2/3) = -15(10) +(-15)(2/3) = -150 -30/3 = -150 -10 = -160

The mixed number can be written as the sum of an integer and a fraction. The multiplier then multiplies the integer and the fraction separately, and the two products are added.

I need help with #7 ?!!! <br> Btw #6 is correct
Musya8 [376]

Choice C for problem 6 is correct. The two angles (65 and 25) add to 90 degrees, proving they are complementary angles.

===========================================

The answer to problem 7 is also choice C and here's why

To find the midpoint, we add up the x coordinates and divide by 2. The two points A(-5,3) and B(3,3) have x coordinates of -5 and 3 respectively. They add to -5+3 = -2 which cuts in half to get -1. This means C has to be the answer as it's the only choice with x = -1 as an x coordinate.

Let's keep going to find the y coordinate of the midpoint. The points A(-5,3) and B(3,3) have y coordinates of y = 3 and y = 3, they add to 3+3 = 6 which cuts in half to get 3. The midpoint has the same y coordinate as the other two points

So that is why the midpoint is (-1,3)

A flyer is spread by people at a large conference. Within one hour, the first person gives a stack of flyers to six people. With
Mandarinka [93]

Answer:

In summation form \sum_{n = 1} ^{5} 6(6)^{n - 1}

Step-by-step explanation:

Within one hour, the first person gives a stack of flyers to six people and within the next hour, those six people give a stack of flyers to six new people.

So, in the first 5 hours, the summation of people that receive a stack of flyers not including the initial person will be given by

6 + (6 × 6) + (6 × 6 × 6) + (6 × 6 × 6 × 6) + (6 × 6 × 6 × 6 × 6).

So, in summation form \sum_{n = 1} ^{5} 6(6)^{n - 1}

Therefore, Sigma-Summation Underscript n = 1 Overscript 5 EndScripts 6 (6) Superscript n minus 1, gives the correct solution. (Answer)
