Hyperbola equation opening horizontally:
\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1
Asymptotes:
y = \pm \frac{b}{a} x

'a' is distance vertex is from center --> a = 9
'c' is distance focus is from center  --> c = 15
a^2 + b^2 = c^2 \\  \\ b^2 = 15^2 - 9^2 = 144 \\  \\ b = 12

Asymptotes are:
y = \pm \frac{12}{9} x = \pm \frac{4}{3} x

Leto [7]

Answer:

2.45c + 1.65c = 4.12 + 0.75

Step-by-step explanation:

To write an equation to find the value for c, we need to declare what c is first.

c = price of fruit

2.45c + 1.65c = 4.12 + 0.75

Now we multiplied c to 2.45 and 1.65 and added them together, because whatever the value of c is will give us the equivalence of the sum of 4.12 + 0.75.

Now to check if the equation is right, let's solve for c.

2.45c + 1.65c = 4.12 + 0.75

4.1c = 4.87

Now to get the value of c, we divide both sides of the equation by 4.1.

\dfrac{4.1c}{4.1}=\dfrac{4.87}{4.1}

c = 1.19

Now let's substitute the value of c in the equation to see if we got it right.

2.45(1.19) + 1.65(1.19) = 4.12 + 0.75

2.92 + 1.96 = 4.87

4.87 = 4.87

Therefore concluding that the value of c is 1.19.
