Answer:
X = -19
Step-by-step explanation:
Add x to both sides to get rid of -x
-163 = 13x + 84
subtract 84 from both sides
-247 = 13x
divide by 13
x = -19
Answer:
15°F at 3:00 a.m.
Step-by-step explanation:
Actually, the median is not the same as the average.
The mean and the average are the same.
To find the median, put these numbers in order.
So 4, 5, 8, 9, 10. Now see which number is in the middle.
It is 8, so 8 is the median number.
Answer: First option. y-15=5(x-3)
Solution:
We can take any pair of points of the table. For example:
P1=(3, 15)=(x1, y1)→x1=3, y1=15
P2=(5, 25)=(x2,y2)→x2=5, y2=25
And we can find the slope m using the following formula:
m=(y2-y1)/(x2-x1)
m=(25-15)/(5-3)
m=(10)/(2)
m=5
Now we can apply the point-slope formula to find the equation of the right line:
y-y1=m(x-x1)
Replacing y1=15, m=5, and x1=3
y-15=5(x-3)
