If we take the equation and multiply out the left side, we get....
+ 2xk +
=
+ x +
The x^2 and k^2 cancel out on both sides leaving us with this...
2kx = x
If we divide both sides by 2x to isolate k,
k ends up = 1/2
Answer:
The increasing interval is from [-5,-2]
The decreasing interval is from [-2,1]
The axis of symmetry is x=-2
there in no minimum
the maximum co - ordinate is (-2,4)
The rule for a rotation by <span><span>90</span></span> about the origin is <span>(x,y)→(−y,x<span>)
A(-2,11) then A(-11,-2)
B(-3,-6) then B(6,-3)
T(10,-4) then T(4,10)
answer
A. the first choice
</span></span>
A would be 0,
0 divided by 4 =0
0/4=0
Answer:
0.66
Step-by-step explanation:
Given that a survey of athletes at a high school is conducted, and the following facts are discovered: 24% of the athletes are football players, 55% are basketball players, and 13% of the athletes play both football and basketball.
Probability for a randomly chosen person is either a football player or a basketball player
=Prob for football player + Prob for basketball player -Prob for both
=
i.e. Probability reqd =0.66
