Hello:
6x²+1 = x²+4
5x² = 3
x² = 3/5
the system has two solutions ( X² =b ..b> 0 has two solutions : ± <span>√b)
</span>x = √(3/5) or x = - √(3/5)
if : x = √(3/5) y = √(3/5) ² +4 =3/5 +4 =23/4
if : x = - √(3/5) y =(- √(3/5)) ² +4 =3/5+4 =23/4
<span>The graphs of the equations intersect each other at two places (points) :
A(</span>√(3/5) , 23/4) and B (-√(3/5) , 23/4)
(3, -7) and (-1, 1)
To find slope of a line using 2 points
we use formula
(3, -7) is (x1,y1) and (-1, 1) is (x2,y2)
Here x1= 3 and y1= -7
x2=-1 and y2=1
=-2
slope of a line using 2 points (3, -7) and (-1, 1) is -2
So first you multiply 2 and 4x to get 8x. Then you multiply 2 and 5 to get 10. So the problem will look like:
8x+10=90
Then you subtract 10 on both sides of the problem to get:
8x=80
And then divide 8 on both sides to get
x=10
