Bethany, Lauren, Amanda, and David all meet at a family reunion. They are comparing their ages. They have found that Lauren is 1

tekilochka [14]

Lauren =l
David=d
Bethany's =x
Amanda =y
l=x+13
d=y+11
lx=2y
(x+13)x=2y
 $2y=x^2+13x$
$y= \frac{1}{2}(x^2+13x)$
or
$y= \frac{x^2}{2}+ \frac{13}{2}x$
(x-20)(l-20)=d
(x-20)(x+13-20)=y+11 
 $y+11=(x-20)(x-7)$
$y+11=x^2-27x+140$
$y=x^2-27x+129$
so I believe its b
Hope this helps :)

What is 5y-4x =-7 2y+4x=14 X=? Y=?

Alja [10]

Answer:

X=3

Y=1

Step-by-step explanation:

In solving simultaneous equations, there are three methods, we have the elimination method, substitution method or graphical method. But for the purpose of this question, we would be using Elimination method.

5y-4x =-7 Equation 1

2y+4x=14 Equation 2

Since x has the same coefficient, it's easy to eliminate by adding up the two equations

5y+2y=7y

-4x+(+4x)=0

-7+(+14)=7

We have 7y=7

Divide both sides by 7,

y=7/7

y=1

Substituting for y in equation 2.

2(1)+4x=14

2+4x=14

4x=14-2

4x=12

x=12/4

x= 3
