Answer:
Question #3: Answer = 31
Step-by-step explanation
• Plug in 3 for x
• Plug in -4 for y
| -3(3)² + 2(-4) | -(3)(-4)
From here, simplify. Don't forget to use PEMDAS!
| -27 +8 | + 12
| -19 | + 12
19 + 12
31
Use this same method to solve for Question #2!
Bring u outside the bracket so u (32 -v + 8u)
B) the value is 20, and the rate of changes is -5
A = 25
Explanation:
Subtract 3 from both sides and get a/5 =5, then multiply 5*5 and get a = 25
