Answer:
x = -7
x = 4
Step-by-step explanation:
The answer will be A
Step by Step Calculation
Length = √((x2 - x1)2 + (y2 - y1)2)
= √((-8-(4))2 + (7-(2))2)
= √(144+25)
= √(169)
= 13
Hello from MrBillDoesMath!
Answer:
The first choice ( -12, 20)
Discussion:
Using matrix multiplication we find the equations:
1x + 1y = 8 (A)
2x + 3y = 36 (B)
Next, compute
2(A) - B =>
(2x + 2y) - (2x + 3y) = 2*8 - 36 =>
(2x - 2x) + ( 2y-3y) = 16 - 36 =>
-y = -20 =>
y = 20
Substituting this y value in (A) gives
x + 20 = 8 =>
x = 8 - 20 =>
x = -12
The answer is the first choice ( -12, 20)
Thank you,
