Answer:
-4x+4y+21
Step-by-step explanation:
-3(2x-7)+2y+2(x+y)
-6x+21+2y+2x+2y
-4x+21+4y
-4x+4y+21
Expanded and simplified :)
Answer:
the correct answer is x=-4
Step-by-step explanation:
the mistake he made is writing 1/4x=-10 instead of 1/4x=-1
He should have wrote -1 instead of -10
Answer:
r·sin Ф = 5(r·cos Ф) - 2
Step-by-step explanation:
y = r·sin Ф and x = r·cos Ф, and so
y = 5x - 2 becomes
r·sin Ф = 5(r·cos Ф) - 2
4(1 + 5n) = -6n - 14 + 8
4(1 + 5n) = -6n -6
4 + 20n = -6n - 6
10 + 26n = 0
26n = -10
n = -10/26 = -5/13.
I believe this would be the solution to the question.
