I am not really sure but I have a feeling it’s (B.)
Answer:
d
Step-by-step explanation:
Substitute x = -1 into the equations. If the solution is y = 4 for both, then (-1, 4) is the solution.
(a) y = 1 + 3 = 4
y = -1 + 1 = 0
(b) -1 - y = 2 ⇒ y = -3
-1 + y = -6 ⇒ y = -5
(c) -1 + y = -2 ⇒ y = -1
7(-1) - 4y = 8 ⇒ y = -15/4
(d) y = 1 + 3 = 4
y = 2(-1) = 6 = 4
Answer:
4
Step-by-step explanation:
In math, the word difference is the result of subtracting one number from another. It refers to the difference in quantity between two numbers. In math, we get the difference between two numbers by subtracting the subtrahend (the number being subtracted) from the minuend (the number being subtracted from).
a. ((x2-x1)^2 + (y2-y1)^2)^(1/2)
(-4-8)^2 + (1-5)^2 144+16= 160
160^(1/2)= 12.64
b. (8-4)/2 & (5+1)/2
4/2=2 6/2=3
(2,3) is the midpoint of AB
