Answer:
14 +2i
Step-by-step explanation:
For this sort of problem, you can treat i as though it were a variable. Combine like terms.
(8 -7i) +(6 +9i) = (8 +6) +(-7 +9)i
= 14 +2i
Answer:
x=-4
Step-by-step explanation:
Dividing both sides by -3, you get x+2=-2. So x=-4.
Answer: 112
Step-by-step explanation:
Since we were given m and n, we plug them into the expression and solve.
-2(-6)+4(-5)² [exponent]
-2(-6)+4(25) [multiply]
12+100 [add]
112
Now, we know that the value of the expression is 112.
Answer:
y=9 (x=-4.5)
Step-by-step explanation:
you have to split the equation up in order to solve
5y=45
divide by 5 on both sides
y=9
-10x=45
divide by -10
x=-4.5
