Answer:
(-1,3)
Step-by-step explanation:
2x-3y=9 multiply by 3 to get 6x-9y = 27
3x+5y=4 multiply by -2 to get -6x-10y= -8
Add together -19y=19, y= -1
Put y into either equation => 2x-3(-1)=9, 2x+3=9, 2x=6, x=3
Answer:

Step-by-step explanation:

- If we use the exponential product rule, then we can add these two exponents together. Using these rules, you can add exponents together when multiplying two values, or you can subtract two exponents when dividing two values. I'll show them below.



- Now we combine the rest together like a normal problem and add the exponents.

- This is our final answer.
Multiplication Property of Equality, i'm pretty sure is your answer you are not very clear in the question
Answer:
B. 3x² – 10x + 13
Step-by-step explanation:
given:
f(x) = 3x² – 8x + 5
g(x) = 2x – 8
f(x) - g(x)
= (3x² – 8x + 5) - (2x – 8)
= 3x² – 8x + 5 - 2x + 8
= 3x² – 10x + 13
