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)
0, 3, -2, 8. You go up 8 rungs and you were halfway there so 16.
Answer:
A (3,0)
Step-by-step explanation:
The vertex is half way between the zeros
Add the zeros together and divide by 2
(2+4)/2 = 6/2 =3
The vertex is at x=3
