If Kaylee was 18 and Lylah was 45 how many years younger would Kaylee be??

SVETLANKA909090 [29]

You are trying to find how much younger Kaylee is than Lylah.

You would subtract her age from Lylah's.

45-18= 27

Kaylee was 27 years younger than Lylah.

I hope this helps!

A plane intersects both nappes of a double-napped cone but does not go through the vertex of the cone. What conic section is for

lisabon 2012 [21]

When a plane intersects both nappes of a double-napped cone but does not go through the vertex of the cone, the conic section that is formed by the intersection is a curve known as hyperbola.
The standard form of the equation of the hyperbola is shown below:
[(x-h)^2/a^2]-[(y-k)^2/b^2]=1 (Horizontal axis)
[(y-k)^2/a^2]-[(x-h)^2/b^2]=1 (Vertical axis)
Therefore, the answer is: Hyperbola.

Reading a Cartesian Plane

Coordinates (x, y)

Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 3)

Point (1, 5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{5-3}{1-0}$
[Slope] Subtract: $\displaystyle m=\frac{2}{1}$
[Slope] Divide: $\displaystyle m=2$
