Answer:
141
Step-by-step explanation:
Answer:
We are given the initial price of a car and we are also told that the car sold for a 15% profit which means that the price that the car was sold for is 15% more than it's initial price. This is just a simple multiplication problem which we multiply the initial price by the total percentage plus 0.15




Therefore, our final answer is that the selling price was $5980

Answer:
y²=4√2.x
Step-by-step explanation:
The focus is at (0,4) and directrix is y=x or x-y =0, for a parabola P.
The distance between the focus and the directrix of the parabola P is
=
{Since the perpendicular distance of a point (x1, y1) from the straight line ax+by+c =0 is given by
}
Let us assume that the equation of the parabola which is congruent with parabola P is y²=4ax
{Since the parabola has vertical directrix}
Hence, the distance between focus and the directrix is 2a =
, {Two parabolas are congruent when the distances between their focus and the directrix are same}
⇒ a=√2
Therefore, the equation of the parabola is y²=4√2.x (Answer)
2^9=512
There are 512 possible solutions
<u>Answer:</u>
x=3
<u>Step-by-step explanation:</u>
3(3 + x)=15+x
<u>distribute</u>
9 + 3x= 15+x
<u>subtract x from each side</u>
9+3x-x = 15
9+2x = 15
<u>subtract 9 from each side</u>
9+2x-9 = 15-9
2x = 6
<u>divide by 2</u>
2x/2 = 6/2
x=3
