Step-by-step explanation:
The equation given is of the form
where (h, k) are the coordinates of the vertex. So in this case, the vertex is located at (4, 2). Since a is a negative number (a = -3), this means that the vertex is a maximum because the parabola opens downward.
Answer:
-3/4 and 1/-2 is the correct answer.
D) 7x+5
hope it helps.
C
x+4y=-12
x+7y=-15
subtract
-3y=3
y=-1
x+4(-1)=-12
x=-12+4=-8
so point is (-8,-1)
y = 30x
y is the amount of money
30 is the constant, the amount of money she gets per x, month
