Aas the 2 a’s are for the little lines that the top and the a is when you don’t have lines
The equation of line that has slope 8 and passes though (2,7) is:
Step-by-step explanation:
Given
Slope of line = 8
passes through (2,7)
Equation of line in slope-intercept form is given by:
Putting the value of slope
Too find the value of b, putting (2,7) in the equation
Putting b=-9 int he equation
Hence,
The equation of line that has slope 8 and passes though (2,7) is:

Hi there!
In order to solve this problem, we can use a couple proportions. First, we'll use this proportion: 1/5 = x/150. Now, cross-multiply: 5x = 150. Then, divide: x = 30. This means that the spinner will hit the section labeled 5, 30 out of 150 times. Now we need to find the percentage. To find the percentage, we'll use this proportion: 30/150 = x/100. Cross-multiply: 150x = 3000. Divide: x = 20. This means that the spinner will land on the section labeled 5, 30 out of 150 times or 20% of the time.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
The peasant had 28 hens and 42 rabbits
<h3>How to determine the number of hens and rabbits?</h3>
Represent hens with h, eggs with e and rabbits with r.
So, we have:
2r = 3h
e = 1/3h
Make h the subject in e = 1/3h
h = 3e
He got 72 pennies.
So, we have:
r + h = 72
Multiply through by 2
2r + 2h = 144
Substitute 2r = 3h in 2r + 2h = 144
3h + 2h = 144
Evaluate the sum
5h = 144
Divide by 5
h = 28.8
Remove decimal
h = 28
Recall that:
2r = 3h
So, we have:
2r= 3 * 28
Divide by 2
r = 3 * 14
Evaluate the product
r = 42
Hence, the peasant had 28 hens and 42 rabbits
