Answer:
The cost of 1 orange y = 1.1
Step-by-step explanation:
Let cost of 1 apple = x
Cost of 1 orange = y
We will make equations from given statements to find the cost of 1 orange i.e y
Wilma bought 3 apples and 6 oranges for $9: Mathematical expression will be:
Fernando bought 6 apples and 2 oranges for $7. Mathematical expression will be:
Let:
Multiply eq(1) by 2 and subtract both equations.
So, We get value of y=1.1
Now, put value of y in eq(1) to find value of x
So, the cost of 1 orange y = 1.1
The required equation of the hyperbola is expressed as
The standard form for calculating the equation of a parabola along the x-axis is expressed as:
where:
(h, k) is the center
(k±c, h) are the foci
is the directrix
From the question given, we can see that foci = (±5, 0)
k±c, h = ±5, 0
k = 0
h = 0
c = 5
From the directrix,
Also, we need to know that;
a²+b² = c²
10 + b² = 5²
b² = 25 - 10
b² = 15
Substituting the gotten values into the equation of a hyperbola;
This gives the required equation of the hyperbola

It would take him 2.5 hrs because when you divide 10 by 4 that's what you get
