Slope = y2 - y1 / x2 - x1
= 8-4 / 3-2
= 4 / 1
= 4
<u>Answer:</u>
x=3
<u>Step-by-step explanation:</u>
3(3 + x)=15+x
<u>distribute</u>
9 + 3x= 15+x
<u>subtract x from each side</u>
9+3x-x = 15
9+2x = 15
<u>subtract 9 from each side</u>
9+2x-9 = 15-9
2x = 6
<u>divide by 2</u>
2x/2 = 6/2
x=3
Answer:
He scored
points.
Step-by-step explanation:
Given:
Number of points for a correct answer = ![2\frac{1}{2}](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D)
Number of points scored for an incorrect answer = ![-\frac{1}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B4%7D)
Therefore, for 35 correct answers, points scored = ![35\times 2\frac{1}{2}=35\times \frac{5}{2}=\frac{175}{2}](https://tex.z-dn.net/?f=35%5Ctimes%202%5Cfrac%7B1%7D%7B2%7D%3D35%5Ctimes%20%5Cfrac%7B5%7D%7B2%7D%3D%5Cfrac%7B175%7D%7B2%7D)
Now, for 32 incorrect answers, points scored = ![32\times -\frac{1}{4}=-\frac{32}{4}=-8](https://tex.z-dn.net/?f=32%5Ctimes%20-%5Cfrac%7B1%7D%7B4%7D%3D-%5Cfrac%7B32%7D%7B4%7D%3D-8)
Therefore, net number of points scored by Nathan is:
![\frac{175}{2}-8=\frac{175}{2}-\frac{16}{2}=\frac{175-16}{2}=\frac{159}{2}=79\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B175%7D%7B2%7D-8%3D%5Cfrac%7B175%7D%7B2%7D-%5Cfrac%7B16%7D%7B2%7D%3D%5Cfrac%7B175-16%7D%7B2%7D%3D%5Cfrac%7B159%7D%7B2%7D%3D79%5Cfrac%7B1%7D%7B2%7D)
Therefore, Nathan scored
points.

If you were supposed to add 0.16 and 0.45, the correct answer would be 0.61.
Answer:
5 hours
Step-by-step explanation:
The total cost is the fee plus the hours* hourly cost
450 = 200+50*h where h is the hours
Subtract 200 from each side
450-200 = 200-200 +50h
250 = 50h
Divide each side by 50
250/50 = 50h/50
5 = h
5 hours
