Answer:
C
Step-by-step explanation:
Given

Divide each term on the numerator by 4x
=
+
+ 
=
+ 2 + 
4-7x= 39
Subtract 4 from both sides
-7x= 35
Divide both sides by -7
x= -5
The value of x+1= (-5)+1= -4.
Answer:
200 √17
Step-by-step explanation:
distance between two points (x,y) and (x',y')
D² = (x' - x)² + (y' - y)²
D² = (500 - (-300))² + (400 - 200)² = 640000 + 40000 = 680000
D = √680000 = √4 x 17 x 10000 = 200 √17
Answer:
The letters I and S are more likely to come out of the bag because they are repeated twice in the word.
point-slope form of a line:

where m is the slope and (x1, y1) is a point on the line.
In the case of:

the slope is 1/5 and the point is (1, 2)
With this information, we can deduce that the point (1+5, 2+1) = (6, 3) is on the line. Connecting these two points we can graph the line as follows:
