Answer:

To make this easier, first draw or imagine a vertical line at x=2

Find where the vertical line and the graph intersects.

Draw or imagine that point of intersection.

Now, draw or imagine a horizontal line that goes through the point of intersection.

That horizontal line tells us the the value of the function by passing through that mark that says "-2"

The function's value at x=2 is -2.

Have an awesome day! :)

Which digit in 1,377,207 has a value that is 1/10 the value of the 7 in the ten thousand place?
Nesterboy [21]

Considering the values of the digits in the number, we have that digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.

<h3>What are the values of the digits in the number 1,377,207?</h3>

We start counting the values from the final number, from 1 and multiplying by 10, hence:

  • Digit 7 has a value of 1.
  • Digit 0 has a value of 10.
  • Digit 2 has a value of 100.
  • Digit 7 has a value of 1,000.
  • Digit 7 has a value of 10,000. -> Ten thousand place.
  • Digit 3 has a value of 100,000.
  • Digit 2 has a value of 1,000,000.

One tenth of the ten thousand place is a value of 100, hence digit 2 has a value that is 1/10 the value of the 7 in the ten thousand place.

The length of a rectangle is 6 ft longer than its width.
nasty-shy [4]

Answer:

135ft²

Step-by-step explanation:

Width = w

Length = w + 6

Perimeter = 48

Perimeter = 2(l + w)

Perimeter = 2(w + 6 + w) = 48

2(2w + 6) = 48

4w + 12 = 48

4w = 48 - 12

4w = 36

w = 36/4

width = 9

length = w + 6 = 9 + 6 = 15

Area = length × width

= 15 × 9

= 135 ft²
