What is the answer to this question?
WARRIOR [948]

Answer: Lower right corner

============================================

Explanation:

The information that the temperature rises 3 degrees per hour will tell us the slope here. The slope is rise/run = 3/1 = 3. Each time we move up 3 on the y axis, we move 1 spot to the right.

As you can see in the bottom right hand corner graph, we start off at a temperature of 20 degrees. This is the point (x,y) = (0,20)

Then one hour later (x = 1), the temperature y bumps up to y = 23. Another hour passes by (x = 2) and y becomes y = 26. And so on.

Please Help, I can't figure out this problem
Otrada [13]

Answer:

<h2>The answer is 5 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d  =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question

The points are (9,-7) and (5, -4)

The distance between them is

d =  \sqrt{ ({9 - 5})^{2} +  ({ - 7 + 4})^{2}  }  \\  =  \sqrt{ {4}^{2}  +  ({ - 3})^{2} }  \\  =  \sqrt{16 + 9}  \\  =  \sqrt{25}

We have the final answer as

<h3>5 units</h3>

Hope this helps you

Find a common denominator for 2,4,8. Which is 8. Change the fractions to new ones.

1) 19 4/8= 156/8 Then add the second. 2) 7 5/8= 61/8 one and the third
3) 5 6/8= 46/8 one. Which is

15/8. Then, subtract your answer and the first one. You get 141. Simplify. 17 5/8

Which of the following equations describes the line shown below , check all that apply
Bond [772]
The line is passing through the y-axis at 3. The slope of the line is 3.
So your equation would be y = 3x + 3.

Now solve A through F to see which equation(s) matches the line.

A. y + 6 = 3(x + 3)
     y + 6 = 3x + 9
     y = 3x + 3

B. y + 6 = 3(x + 1)
     y + 6 = 3x + 3
     y = 3x - 3

C. y - 6 = 3(x - 3)
     y - 6 = 3x - 9 
     y = 3x - 3

D. y - 6 = 3(x - 1)
     y - 6 = 3x - 3
     y = 3x + 3

E. y = 3x + 2

F. y = 3x + 3

Which letters equaled y = 3x +3?
A, D, and F.

The equations that describe the line are A, D, and F.
