Answer: perpendicular lines
Step-by-step explanation:
look up "Two straight lines that intersect at a right angle"
First you subtract the two equations
x^2-2x+3-6x
You simplify that and get
x^2+4x+3 = 0
Now we solve using the quadratic formula.
We get x = -1 and x = -3.
Now we find the y values by plugging the x values into the equation.
f(x) is the same as y.
y = (-1)^2 - 2(-1) + 3
y = 1+2+3
y = 6
Now for the other x value.
y = (-3)^2 - 2(-3) + 3
y = 9+9
y = 18
So the two ordered pairs are (-1,6) and (-3,18)
1
Add 1111 to both sides
5x\ge 31+115x≥31+11
2
Simplify 31+1131+11 to 4242
5x\ge 425x≥42
3
Divide both sides by 55
x\ge \frac{42}{5}x≥542
