Answer:
3rd Choice
Step-by-step explanation:
The third answer choice is correct, remember that a shape is not a rectangle or square if it doesn't have four 90 degree angles.
We can use substitution.
We can substitute 2x + 3 for 'y' in the 2nd equation.
y = 3x + 5
2x + 3 = 3x + 5
Subtract 3 to both sides:
2x = 3x + 2
Subtract 3x to both sides:
-x = 2
Multiply -1 to both sides:
x = -2
Now we can plug this into any of the two equations to get our y-value:
y = 2x + 3
y = 2(-2) + 3
y = -4 + 3
y = -1
So our solution is (-2, -1)
Did you try adding all the sides like this: 6+2+6+12+16+6+12=?
Im pretty sure he earned 495 in interest, because you take 5,500 time .03 (from the three percent) and you get 165- then multiply by three because of the three years (495)
