Iteru [2.4K]3 years ago

Answer:

The answer is "3".

Step-by-step explanation:

If the compression factor of 3 is modified, the k value is 3 For a function f(x) the horizontal extending or compression is provided by g = f (bx)

Here b is constant. Where b is constant.

If b> 0, the function graph is condensed. The fact that perhaps the function is transformed by an encoding factor of 3 is given in the question.

\to f(x)=7^x+1\\\\\to g=f(b(x))

Helen has an old laser printer that can print 900 pages in 1.5 hours. If the speed of printing remains constant, how
lilavasa [31]

Answer:

1 hour

Step-by-step explanation:

No. of pages print in 1.5 hours = 900

dividing LHS and RHS by 1.5 so that we get 1 hour in LHS

no. of page print in 1.5/1.5 (1) hours = 900/1.5 = 600.

Thus, it takes 1 hour to print 600 pages.

Given that we have to find  how

long will it take her to print a book of 600 pages.

Answer is 1 hour.

8. The larger of two numbers is 8 more than twice the smaller. The sum of the
schepotkina [342]

Answer:

Step-by-step explanation:

Givens

smaller number = x

Larger number = 2x + 8

Sum = 35

Equation

x + 2x + 8 = 35

Solution

3x + 8 = 35

3x = 35 - 8

3x = 27

x = 9

The smaller number = 9

The larger number = 2*9 + 8 = 26

My answers aren't in the list. Are you sure the numbers in the list are correct?

Can you help me solve systems of equations by elimination step by step<br> 6x+y=15<br> -7x-2y=-10
Anna71 [15]

Answer:   (4, -9)

<u>Step-by-step explanation:</u>

Use elimination method.  Manipulate one (or both) equations to eliminate one of the variables and solve for the remaining variable.  <em>I will be eliminating y</em>

6x +  y =  15    → 2(6x +  y =  15)   →   12x + 2y = 30

-7x - 2y = -10   → 1(-7x + 2y = -10)   →  <u> -7x - 2y = -10</u>

                                                             5x        = 20

                                                               x         =  4

Next, replace "x" with "4" into either equation and solve for y.

6(4) + y = 15

24  + y = 15

         y  = -9


<u>Check:</u>

Plug in x = 4 and y = -9 into the other equation to verify it makes a true statement.

-7x - 2y = -10

-7(4) - 2(-9) = -10

-28  -   -18  = -10

-28  +  18 = -10

       -10    =  -10  \checkmark

ExtremeBDS [4]

Answer:

$944

Step-by-step explanation:

<h3>Interest=principle*rate*time (in years)</h3><h3>I=prt</h3>

<em>Principle=800</em>

<em>Rate=0.06 (6%)</em>

<em>Time=3</em>

<em>800*0.06*3= 144</em>

Total

Principle+Interest= Total

800+144=944

alexdok [17]
An easy way (you must put the numbers in the correct side)

3 2 you cant subtract 5 from 2 so u carry one
-1 5 the 3

2 ¹3. it should look like this.Now u do 13-5=8
-1 5

2 ¹3. now u do 2-1=1
- 1 5
= 1 8
