[(9 + 7i)/(-10 + 8i)] * [(-10-8i)/(-10-8i)]
[(9+7i)(-10-8i)] / [(-10+8i)(-10-8i)]
[(9+7i)(-10-8i)] / (100 + 64)

Answer:
x = 29
Step-by-step explanation:
Added together equals to 180 degrees. Write out the equation:
x + 35 + 4x = 180
5x + 35 = 180 (Add the x together)
5x = 145 (Minus both sides by 35)
x = 29
Answer:
b)
The point is (-1,5) and (0,0) also satisfies the given inequalities
The solution of the given inequalities
(x, y) = (4 , -2 )
Step-by-step explanation:
<em>Step(i):</em>-
Given system of equations are
3x + 2y < 8
-5x - 9y > -2
The solution of the given equations are
3x + 2y = 8 multiply '5'
-5x - 9y = -2 multiply '3'
15 x + 10 y = 40 ...(i)
-15x - 27 y = -6.....(ii)
Adding (i) and (ii) , we get
- 17 y = 34
y = -2
Substitute y = -2 in equation 3x + 2y =8
3x - 4 =8
3x = 12
x =4
The solution of the given system of inequalities
(x, y) = (4 , -2 )
<u><em>Step(ii)</em></u>:-
3x + 2y < 8
-5x - 9y > -2
The point is (-1,5)
-3 + 10 < 8
7 < 8
5 - 45 > -2
-40 > -2
The point (0,0) also satisfies the given inequalities
Final answer :-
The point is (-1,5) and (0,0) also satisfies the given inequalities
The correct word is degrees
The answer is a s7 * a s5
