Which is a solution to the equation 5x – y = –3? A. (1, 2) B. (–2, –7) C. (–2, 7) D. (2, –7) can you please help
2 answers:
5x - y = -3......this is just a matter of subbing in ur answer choices to see which one makes the equation true.
5x - y = -3.....subbing in (-2,-7)...x = -2 and y = -7
5(-2) - (-7) = -3
-10 + 7 = -3
-3 = -3 (correct)
so ur answer is : B. (-2,-7) <==

Hi...the answer is b.. I would recommend plot graph and find the gradient.... then use the point formula
Equations:
A + T = 735 naira
A = T + 95
A + T = 735
A - T = 95
Add and solve for A:
2A = 830
A = 415 naira
T = 735-415 = 320
the answer to 54,000 x 10 is 540,000
8x +(5.5)y=78.50 is the equation.
