Answer:
<h2>regular nonagon</h2>
Step-by-step explanation:
Look at the picture.
To obtain these 2 points within slope intercept form, what you would need to do, is first find the slope, using the formula for slope.
M = y2-y1/x2-x1 = 3 - 2/1 - 5 = 1/-4 or -1/4.
Knowing this, choose any one of the point and put it in the form y = mx + b.
Y = mx + b
2 = -1/4(5) + b
2 = -5/4 + b
2 = b - 5/4
b = 5/4 + 2/1
b = 5/4 + 8/4 = 13/4
Y = -1/4x + 13/4.
Answer:
Step-by-step explanation:
The sum of two even numbers is an even number
The answer is 11 because you add all the numbers then divide by the number of terms which would be 44/4=11
Answer:
31 children and 290 adults
Step-by-step explanation:
Let a = number of adults and c = number of children.
a + c = 321
2a + 1.75c = 634.25
Multiply both sides of the the first equation by -2 and add it to the second equation.
-2a - 2c = -642
(+) 2a + 1.75c = 634.25
--------------------------------------
-0.25c = -7.75
Divide both sides by -0.25
c = 31
Use the first equation to find a.
a + c = 321
Substitute 31 for c.
a + 31 = 321
Subtract 31 from both sides.
a = 290
Answer: 31 children and 290 adults
