Answer:
A Exactly one solution
Step-by-step explanation:
Putting y=0 at second equation, we have
The unique solution is 
When you want to find a percent of a number you do this:
given number/ 1 multiplied by percentage/100
so in this question its a multiple step
start with finding 25 percent of 4250 which is= 1062.5
so thats how much the discount is so the amount after the 25% discount is:
4250-1062.5= 3187.5
then you have to add 9% due to fees
so you find 9% of 3187.5 which is= 286.875
so you add 286.875 to 3187.5 gives you= 3437.375 in total cost for the vacation package
<span>9 + (-4) - 6
<em>[open the bracket, +(-) = - ]</em>
</span>= 9 - 4 - 6
<em>[Both operations required are -, work from left to right]</em>
= 5 - 6
= - 1
Answer:
Parabolas are frequently used in physics and engineering for things such as the design of automobile headlight reflectors and the paths of ballistic missiles. Parabolas are frequently encountered as graphs of quadratic functions.
