We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
4x + 5y = -12
-2x + 3y = -16
<u>Step 2: Rewrite Systems</u>
-2x + 3y = -16
- Multiply everything by 2: -4x + 6y = -32
<u>Step 3: Redefine Systems</u>
4x + 5y = -12
-4x + 6y = -32
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine 2 equations: 11y = -44
- Divide 17 on both sides: y = -4
A) an equal chance or 50-50
There is the same amount of each flavor so it has an equal chance of being cherry or strawberry.
