The answer is true. The sequence is arithmetic
An equation in standard form of the given ellipse is; x²/9 + y²/36 = 1
<h3>How to find the equation of an ellipse?</h3>
We know that the general standard form of equation of an Ellipse is;
x²/a² + y²/b² = 1
where;
a is the vertex and b is the co-vertex.
Thus, the equation here is;
x²/3² + y²/(-6)² = 1
⇒ x²/9 + y²/36 = 1

The answer is (4,2) because it just is
Pj = prop jet speed
pp = private plane speed
pj is 2.5 times faster than pp, therefore
A) pj = 2.5*pp
B) pj = 2*pp + 60
Substituting equation A into B
B) 2.5*pp = 2*pp +60
.5 * pp = 60
Private Plane travels at 120 mph
Prop jet = 2.5 * private plane = 300 mph
