Ok, ranked by axis of symmetry
basically x=something is the axis of symmetry
the way to find the axis of symmetry is to convert to vertex form and find h and that's the axis of symmetry
but there's an easier way
for f(x)=ax^2+bx+c
the axis of symmetry is x=-b/2a
nice hack my teacher taught me
so
f(x)=3x^2+0x+0
axis of symmetry is -0/(3*2), so x=0 is the axis of symmetry for f(x)
g(x)=1x^2-4x+5,
axis of symmetry is -(-4)/(2*1)=4/2=2, x=2 is axis of symmetry for g(x)
h(x)=-2x^2+4x+1
axis of symmetry is -4/(2*-2)=-4/-4=1, x=1 is the axis of symmetry for h(x)
0<1<2
axisies
f(x)<h(x)<g(x)
order based on their axises of symmetry is f(x), h(x), g(x)
No because there are no x values
Minus 3y both sides
2y-6=-20
add 6 to both sids
2y=-14
divide 2
y=-7
Answer:
<em>Solution: x=5</em>
Step-by-step explanation:
<u>Equations</u>
This is an equation in the form of a proportion or ratio:
To solve it, we eliminate the denominators by multiplying by both of them.
Multiply by (x+3)(4x):
Simplify both sides:
Operate:
Simplify:
Solve for x:
Solution: x=5
