42/45 with in simplest form would equal to 1 14/42
Answer:
No Solution
Step-by-step explanation:
Divide both sides of the equation by -3. Simplify the expression.
-2x-y=5
2x+y=8
Sum the equations vertically to eliminate at least one variable
0=13
The statement is false for any value of x and y, so there's no solution.
Answer:
-8i
Step-by-step explanation:
To multiply numbers is polar form
z1 = r1 ( cos theta 1 + i sin theta 1)
z2 = r2 ( cos theta 2 + i sin theta 2)
z1*z2 = r1*r2 (cos (theta1+theta2) + i sin (theta1+theta2)
z1 = 2(cos 70° + i sin 70°)
z2 = 4(cos 200+ i sin 200)
z1z2 = 2*4 (cos (70+200) + i sin (70+200)
z1z2 = 8 (cos(270) + i sin (270))
= 8 (0 + i (-1))
=-8i
Answer: x = 13
Step-by-step explanation:
8x + 2 = 14x - 76
78 = 6x
x = 13
