A.
U = –11, W = 7
B.
U = –8, W = –6
C.
U = –6, W = 6
D.
U = 0, W = 2
Answers
distance from U to V = -2-(-11)=9
distance from U to W =7-(-2)=9 -> same distance !
checking answer B:
distance U-V : -2-(-8)=6
U-W : -2-(-6)=4 -> not the same distance
answer C :
U-V : -2-(-6)=4
U-W : 6-(-2)=8 -> not the same distance
answer D :
U-V : 0-(-2)=2
U-W : 2-(-2)=4 -> not the same distance
Conclusion : answer A
C -6, 6-6 is 4 away from -26 is 8 away from -2
You have to find out which two points are the same distance from -2.

Answer: is the required expression.
Step-by-step explanation:
Since we have given that
Length of tree initially = 36 inches
Length of tree after one year = 43 inches
We need to find the percentage of increase in the tree's height.
So, expression would be
Hence, is the required expression.
(43 - 36) ÷ 36 = 7 ÷ 36 = 0.1944 * 100% = 19.44%
36 is the basis of the equation. It is the 100%
7 is the increase in height (inches). It is the 19.44%
43 is the total height. It is 119.44% height of the tree.
Whatever height the tree grow to, if the question is percentage since it was planted, then 36 inches is the basis.
If the problem refers to the height increase based on the latest height measurement, then 43 inches is the basis.
If the 7 inches increase in height is constant every year. Then, an equation will show:
y = 36 + 7x
where y is the total growth through the years. 36 is the initial height, 7 is the constant rate of growth, and x is the number of years the tree has grown.

Answer:
standard form is 45x -12y -100 = 0.
Step-by-step explanation:
Given the equation is -3/2x=-2/5y-10/3.
Finding common denominator, L.C.M.(2,5,3) = 30.
Multiplying both sides by 30.
30*(-3/2x) = 30*(-2/5y-10/3)
-45x = -12y -100
Moving all terms on left side, keeping right side equal to 0.
-45x +12y +100 = 0
Making x's coefficient positive by changing all signs.
45x -12y -100 = 0
Hence, standard form is 45x -12y -100 = 0.
Answer:
Step-by-step explanation:
You want to rewrite the equation
Ax +By=C A,B,C are integers
30(-3/2x) = 30(-2/5y-10/3)
-45x = -12y - 100
-45x + 12y = -100

(4-(-1))/(-3-2)=5/-5 and dividing a negative by a positive=a negative so the slope is -1
the answer is B
x1 = -3, y1 = 4, x2 = 2, y2 =-1
m = (y2 - y1) / (x2 - x1).
m = (-1 - 4)/(2 - - 3).
m = -5/ (2 + 3) = - 5/5.
m = -1
Therefore slope, m = -1. So it is option B.
