Answer:

500

Step-by-step explanation:

Convert percent to decimal:

94%=

100

94

​

=0.94

Move decimal 2 places to the left

Multiplying the decimal by the whole gives us the part:

0.94x=

0.94x=

470

0.94

0.94x = 0.94

470

​

Divide both sides by 0.94x=

a system of equations is graphed here. which system of equations does the graph represent? A) y = 3x + 2y = -2x + 5 B) y = 3x -
n200080 [17]

Notice that the line with negative slope has a y-intercept of 5 and the line with positive slope has a y-intercept of 2.

On the other hand, the slope of the line with negative slope is -2, while the slope of the line with positive slope is 3 (This can be identified since in one case, the value of y decreases by 2 for each increase of 1 unit in x, and in the other, the value of y increases by 3 for each increase of 1 unit in x).

Using the y-intercept form to represent each line, the system of equations represented by the graph must be equivalent to:

\begin{gathered} y=-2x+5 \\ y=3x+2 \end{gathered}

From the given options, the one that displays the correct system of equations is option A.

Therefore, the answer is:

\begin{gathered} A) \\ y=3x+2 \\ y=-2x+5 \end{gathered}

Martina creates the graph of function g by applying a transformation to function f.
MrRa [10]

Answer:

B.a vertical shift of 9 units up

Step-by-step explanation:

Given f(x) = 4x-2\\g(x) = 4x+7

g (x) = f (x) + k

It means shifting f (x)\ k unit vertically.

Now, we will find the value of k for the given function

g(x) = 4x+7\\\\add\ 2\ and\ subtract\ 2\\\\g(x) = 4x+7+2-2\\g(x) = 4x-2+9\\\\We\ have\ f(x)=4x-2\\\So,\ g(x)=f(x)+9

k=9

Hence, vertical shift of 9 units.

Logan's e-reader sent a notification saying that he has completed 75% of the e-book.
Vika [28.1K]

Answer:

The total number of pages in the e-book is 240.

Step-by-step explanation:

Given:

Logan has completed 75%

Logan has read 180 pages

To Find:

The total number of pages in the e-book= ?

Solution:

Let X be the total number of pages on the e-book

then

=> 75% of X = 180

Now lets find the value of X

X = \frac{180}{75\%}

X = \frac{180}{\frac{75}{100}}

X = \frac{180}{0.75}

X = 240
