Answer:
x=-4/5
Step-by-step explanation:
8/20=x/-2
simplify 8/20 into 2/5
2/5=x/-2
cross product
5*x=-2*2
5x=-4
x=-4/5
First, subtract y2 - y1 to find the vertical distance. Then, subtract x2 - x1 to find the horizontal distance.
Formula to find distance given two points.
Square root (X2 - X1)^2 + (Y2 - Y1)^2
Xa Ya Xb Yb
A = (3, -4) B = (-1, 3)
Xa goes into X2 and Xb goes into X1
(3 - (-1))^2
Ya goes into Y2 and Yb goes into Y1
(-4 - 3)^2
Square root (3 - (-1))^2 + (-4 - 3)^2
Square root (4)^2 + (-7)^2
Square root 16 + 49
Square root 65
= 8.06
The error was Drako had (3 - 4)^2 when it should have been (3 - (-4))^2 because a positive is subtracting a negative.
Answer:
C
Step-by-step explanation:
The equation of a line is given by the formula 
Where
is the x-coordinate (it is given as 5)
is the y-coordinate (it is given as 1), and
m is the slope (it is given as -3)
Plugging in all the info into the formula we have:

From the answer choices, we see that C is the correct answer.
Answer:
Slope = 4
Step-by-step explanation:
Use any two pairs from the table of values, say (0, 3) and (2, 11).
Slope = ∆y/∆x
Slope = 
Slope = 
Slope = 4
Answer:
30,114.3%
Step-by-step explanation:
Use the percent increase formula:
((new value - initial value) / initial value) x 100
Plug in the values:
((211,500 - 700) / 700) x 100
(210,800 / 700) x 100
= 30,114.29
So, the percent increase is 30,114.3%
