For this case, the first thing we must do is define variables.
We have then:
x: Maggie's age
y: Age of Maggie's brother
We write the system of equations that models the problem.
We have then:
We solve the system of equations.
For this, we use substitution:
From here, we clear the value of x:
Answer:
Maggie is 9 years old
Answer:
the corrrect answer is A . 12x²y + 6 xy +9x + 9
Step-by-step explanation:
hope my answer is correct
First you add them up and that equals 20. Then you divide by 4. So the average is 5 :)
I think it is 5 because BA is 8 which is congruent to RQ. AD is 12 which congruent to QT. the rhombus or whatever it is just shrunk -3 so 8-3 is 5
Answer:
The slope would be -2 with a y-intercept of (0, -3).
I hope this helped to answer your question.
