7x - 5 = 3x + 7

7x - 5 - 3x = 3x - 3x + 7

4x - 5 = 7

4x - 5 + 5 = 7 + 5

4x = 12

x = 12/4

I don’t understand at all
Savatey [412]

Answer and Step-by-step explanation:

The parent function, f(x) = |x|, has no transformations applied to it.

When the number is with the x, it translates the graph horizontally. <->

When the number is outside of the absolute box, it translates the graph vertically. ^ V

When the number is multiply the absolute box on the outside with the x inside, it scales the graph.

So, first lets apply the translations of horizontal and vertical shift.

The graph translated 1 units downwards.

The graph translates 2 units to the right.

g(x) = |x - 2| - 1

We subtract the 2 because that makes it go right, while if we added it would go left.

Now for the scale.

The lines have a slope of \frac{1}{4}, so that is what we are multiplying.

<u> g(x) = </u>\frac{1}{4}<u>|x - 2| - 1</u>

<u></u>

<u>^That is your transformed function.</u>

Round each measurement to the nearest ten. Then estimate the area of the rectangle.
Ainat [17]

Answer:

4000 sq inches

Step-by-step explanation:

A rectangle is given with sides 82 and 46 inches

We have to round off these dimensions to the nearest 10.

82 inches ~80 inches since 2 <5, we make it 0

Similarly 46 inches ~50 inches since 6>5

Now area

= length x width

=80(50)

=4000 square inches

Option 2 4000 sq inches is correct answer.
