Hello,
a(28)=a(0)+27*8=-3+27*8=213
Answer A
4x + 5y - 3 = 0
4x + 5y = 3
3x - 7y - 13 = 0
3x - 7y = 13
4x + 5y = 3......multiply by 3
3x - 7y = 13....multiply by -4
---------------
12x + 15y = 9 (result of multiplying by 3)
-12x + 28y = - 52 (result of multiplying by 4)
---------------add
43y = -43
y = -43/43
y = -1
3x - 7y = 13
3x - 7(-1) = 13
3x + 7 = 13
3x = 13 - 7
3x = 6
x = 6/3
x = 2
so ur solution is : (2,-1) <==
Answer:
46
Step-by-step explanation:
Angle CED and GHE are equal as the lines are parallels. Also, the line rom D to F will be a total of 180.
Therefor, substract the angle FEC from 180 and you get the angle CED which is equal to GHE
