Answer:
The answer is B
Step-by-step explanation:
1)
These are in Y = MX + B form
The first line has a positive slope, so the coefficient "M" is positive.
The second line has a negative slope, so the coefficient "M" is negative.
2)
The first line has a filled in dot at Y = 2.
Since it's to the left (less than X direction)...
X <= 0
The second has an empty circle at Y = 4.
Since the line goes to the right....
0 < X
3)
Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.
From these things, we can infer that B is the correct answer.

okay
I think you should use the method of tan 30
and then find x by using pythagorean theorem
Answer:
11.5
Step-by-step explanation:
4th route of 7 is 1.63
1.63 to the 5th power is 11.5
Answer:
y= 8x + 5
Step-by-step explanation:
y = 8x + b
5 = 8(0)+b
b = 5
If 75% liked skating, then 25% did not
so 25% of what is 35
0.25x = 35
x = 35/0.25
x = 140...so there is a total of 140 students
75% of 140 =
0.75(140) = 105...so 105 students liked skating
