Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
36 = 1/2 (AE - 26)
72 = AE - 26
98 = AE
B) 9 is the answer for ur question
1) Now,
a + 27° = 90° (right angle triangle)
◆ a = 63°
2) Now,
b + b + b = 90° (right angle triangle)
or, 3b = 90°
◆ b = 30°
3) Now,
c + c + 40° = 90° (right angle triangle)
or, 2c = 90° - 40°
or, c = 50°/2
◆ c = 25°
4) Here,
◆ e = 41° (vertically opposite angle)
◆ f = 82° ( vertically opposite angle)
Now,
d + e + f = 180° (straight angle)
or, d + 41° + 82° = 180°
or, d = 180° - 123°
◆ d = 57°
Then,
◆ g = d = 57° (vertically opposite angle)
It is all correct answer...
I hope u understand...
