Since you have two equations that equal y, you can set them equal to themselves, so 3x+20=x^2+2x
If you move those all over to one side, you get that x^2-x-20=0. From there you can factor out into two parts, (x-5)(x+4)=0. So for this set of equations you can know that the values of x where they intersect are -4 and 5.
All you need to do now is choose an equation to input the values in to solve for y. So, y= 3(-4)+20=8 when x=-4 and y=3(5)+20=35 when x=5. Therefore the two points at which they intersect are (-4,8) and (5,35)
Isn't Hazel G. Lancaster from a movie, In fact, it is actually from The Fault in Our Stars. Which happens to be my favorite movie of all time. And one of the main character's name is Hazel Grace Lancaster.
Seriously, "Augustus Waters". I bet you aren't nearly as cute as him, a.k.a Ansel Elgort. Why do you guys insist on torturing me, LEAVE THE BEST CHARACTERS IN THE WORLD OUT OF THIS. ( Just so you know Hazel Grace Lancaster's real name is Shailene Woodley. Both Ansel and Shailene appear in the Divergent series.) Also check out Ansel Elgort's Album, Yes he sings!
solve the system of equations algebraically. show all your steps. y=x^2+2x y=3x+20 Can someone show me step by step on how to get the answer it's, there are answers like this that is going to be on my math test and I don'tget it.
I am stuck on trying to figure out how to do this question. Could someone please show me 5 necessary steps ? Thank you. Here is how the assignment question is worded. Select any two integers between -12 and +12 which will become
1. Select any two integers between -12 and +12 which will become solutions to a system of two equations. 2. Write two equations that have your two integers as solutions. Show how you built the equations using your integers. Your
