We have that
<span>y=mx−2
y=x</span>²
if the line <span>intersects a the parabola in one point
so
mx-2=x</span>²-------> x²-mx+2=0
<span>Find the discriminant D=b</span>²-4ac
a=1
b=-m
c=2
D=m²-8
we know that
If D<span> is negative ------> Then the square root is imaginary and there is no solution
If </span>D<span> is </span>0<span> then there is exactly one solution
if </span>D<span> is positive there are two solution </span>
therefore
equals D to zero
m²-8=0-------> m=(+/-)√8
the answer is m=(+/-)√8
see the attached figure
m has two solutions
Answer:
a) - 10
Step-by-step explanation:
The two angles are vertical angles:
Angles that have a common vertex and whose sides are formed by the same lines.
Therefore, set your formula up as following
x+5=2x-5
x + 5 - 2x = -5
-x + 5 = -5
-x = -10
Answer: 20/ 60 = 1/3
Step-by-step explanation:
60 beads in total which makes that the denominator and how many red beads in the numerator (20) then just reduce the fraction
