2x +5y=10 writing equations in slope intercept form
rosijanka [135]
Answer: y=-2/5x+2

Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2

The measure of an angle is three more than twice its supplement. What is the measure of the angle?
Zinaida [17]

Answer: the angle is 1°+n×120°

1°, 121°, 241°


Step-by-step explanation:

Angles are taken modulo 360°, so 363° = 3°.

Angle plus supplement gives 180°.

Let a be angle, s be supplement of a.

So s = 180-a. Given a = 3 + 2s

a = 3 + 2(180 - a)

a = 3 + 360 - 2a = 363 - 2a


3a = 363° or 3° or 723°

a = 121° or 1° or 241°


a = 1°

s = 179°

2s = 358°

2s+3 = 361° = 1° (modulo 360)


a = 121°

s = 180-121 = 59°

2s = 118°

2s + 3 = 121°, as required.


a = 241°

s = 360+180-241 = 540-241 = 299

2s = 598

2s + 3 = 601 = 241 (modulo 360)

he dot plot shows the number of words students spelled correctly on a pre-test. A number line going from 2 to 11. 0 dots are abo
Klio2033 [76]
<h3>Answer: B. Graph is nearly symmetrical</h3>

Explanation:

Given information:

  • A number line going from 2 to 11.  
  • 0 dots are above 2.  
  • 0 dots are above 3.  
  • 1 dot is above 4.  
  • 2 dots are above 5.  
  • 4 dots are above 6.  
  • 4 dots are above 7.  
  • 3 dots are above 8.  
  • 2 dots are above 9.  
  • 2 dots are above 10.  
  • 0 dots are above 11.

From that we can see the data set is {4,5,5,6,6,6,6,7,7,7,7,8,8,8,9,9,10,10} which produces the dot plot you see in the image attachment below.

It's a bit tricky to see, but the graph is nearly symmetrical. If we were to remove the blue points in the dot plot I provided, then we'll get a perfectly symmetrical distribution. Symmetrical means one half is a mirror copy of the the other half. The center line of a symmetrical distribution is both the mean and median.
