Answer:
Step-by-step explanation:
15 plus 15 plus 15 is 45 - 15 =30
Answer:
x= -2 and 9
Step-by-step explanation:
factorize it
- 18 = 2×3×3
TO MAKE IT 7
3×3=9
9-2 =7
x(x+9)-2(x+9)=0
x-2=0 ,x+9=0
x =2 x=-9
We'll first clear a few points.
1. A hyperbola with horizontal axis and centred on origin (i.e. foci are centred on the x-axis) has equation
x^2/a^2-y^2/b^2=1
(check: when y=0, x=+/- a, the vertices)
The corresponding hyperbola with vertical axis centred on origin has equation
y^2/a^2-x^2/b^2=1
(check: when x=0, y=+/- a, the vertices).
The co-vertex is the distance b in the above formula, such that
the distance of the foci from the origin, c satisfies c^2=a^2+b^2.
The rectangle with width a and height b has diagonals which are the asymptotes of the hyperbola.
We're given vertex = +/- 3, and covertex=+/- 5.
And since vertices are situated at (3,0), and (-3,0), they are along the x-axis.
So the equation must start with
x^2/3^2.
It will be good practice for you to sketch all four hyperbolas given in the choices to fully understand the basics of a hyperbola.

Answer:
There is 1/4 of a quart of papaya juice
Step-by-step explanation:
To figure this out I divided 8 and 8 to get one cup of carrot juice. Then I divided 2 and 8 to figure how much papaya juice was there for one cup of carrot juice. Then after I divided for the papaya I got 0.25 or 1/4 of a quart of papaya.
