DBA stands for discussion based assignment. so you go to the meeting and talk about your strengths and weaknesses
4x + 5y = -13
2(4x + 5y) = 2(-13)
8x + 10y = -26 (equation 1)
5x - 2y = -8
5(5x - 2y) = 5(-8)
25x - 10y = -40 (equation 2)
equation 1 + equation 2,
(8x + 10y) + (25x - 10y) = (-26) + (-40)
8x + 10y + 25x - 10y = -26 + -40
33x = -66
x = -2
substitute x = -2 into equation 1,
8x + 10y = -26
8(-2) + 10y = -26
-16 + 10y = -26
10y = -10
y = -1
The values of x and y are -2 and -1 respectively.
Answer
54
Step-by-step explanation:
2x+2+3x-52
Combine like terms
3x-2x=x
52+2=54
x=54
Answer:
-2
Step-by-step explanation:
4+3u=-2
3u=-2-4
u=-6/3
u=-2
X1 + x2/2 , y1 = y2/2
xE + xF/2 , yE + yF/2
So it is C or D, becuase they are the same answer choices
