In a function, each x-coordinate can be used only once.
If you have two points, one above the other on the same vertical line, it is not a function.
You are correct.

The upper, right-hand graph represents a function.  Why?  Because there is never more than one value of y for any given x.

If you use the vertical line test on the other 3 problems, you'll see that for some x, the line goes thru more than just one black dot.

Graph this compound inequality 2.5 is equal to or less than x is equal to or less than 4.5
Oxana [17]

Graph this compound inequality 2.5 is equal to or less than x is equal to or less than 4.5

2.5 <= x < = 4.5

We graph this inequality using number line.

Here x lies between 2.5  and 4.5

While graphing, we start with closed circle at 2.5 because we have equal symbol .

Then shade till 4.5. Use closed circle at 4.5.

The graph is attached below.

Answer:

  • B. 630 ft

Step-by-step explanation:

<u>Given:</u>

  • Horizontal leg of the right triangle = 778 ft
  • Angle opposite to vertical length = 39°
  • Vertical leg = h

<u>Use tangent to solve for h:</u>

  • h/778 = tan 39°
  • h / 778 = 0.81
  • h = 0.81*778
  • h = 630.18

Correct choice is B

Find the missing coordinates y+7x=1<br><br> (-1, )<br> (4, )
Pachacha [2.7K]

Answer:

(-1,8)

(4,-27)

Step-by-step explanation:

y+7x=1

Let x = -1 and find y

y+7(-1)=1

y -7 =1

Add 7 to each side

y-7+7 = 1+7

y = 8

(-1,8)

Let x = 4 and find y

y+7(4)=1

y +28 =1

Subtract 28 from each side

y+28-28 = 1-28

y = -27

(4,-27)
