Step-by-step explanation:
x be the number of oranges
x + (x+2) = $4.20
2x + 2 = 4.20
2x = 2.20
x = 1.1
if you wanna check,
1.1 + (1.1 + 2) =$4.20
1.1 + 3.1 =$4.20
4.2 =$4.20
Alex = x = 1.1 oranges
Bobbie = (x+2) = 1.1 + 2 = 3.1 oranges
I'm not sure of the answer tho^^
Answer:
See below
Step-by-step explanation:
It opens upwards ( bowl shaped) (vertex is on one side and focus on other with focus inside the parabola)
axis of symmetry is x = -8
vertex is (-8,0)
5/x = -9
5 = -9x (we have multiplied x out from the denominator)
5/-9 = x (divided by -9 to isolate x)
B.) f(x)=(x^2-3)^2
a.) f(x)= (x^2+6)(x^2+5)
24ab+ab-7
=25ab-7
