2.6\le2.6 classifies as \text{true}

-6 classifies as \text{false},

3.1>-3.1 classifies as \text{true}

so -5\ge -5 classifies as \text{true}

To classify the statements, we need to evaluate each of them:

\text{Evaluate }2.6\le2.6\\\implies (2.6

so 2.6\le2.6 classifies as \text{true}, since the statement also allows 2.6 to be equal to itself.

\text{Evaluate }-6

so -6 classifies as \text{false}, since -6 is equal to itself, not smaller.

\text{Evaluate }3.1>-3.1\\\implies \text{true}

so 3.1>-3.1 classifies as \text{true}, since x>-x, for all real numbers

\text{Evaluate }-5\ge-5\\\implies (-5>-5)\text{ or }(-5=-5)\\\implies \text{false  or  true}\\\implies\text{true}

so -5\ge -5 classifies as \text{true}, since the statement also allows -5 to be equal to itself.

What is the vertex of the quadratic function f(x) = (x – 8)(x – 2)?
LekaFEV [45]
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9

vertex is at (5,-9)

the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever


verrtex is at (5,-9)

A store manager predicts that 115 hats will be sold if each hat costs $18. The manager predicts that 3 less hats will be sold fo
8_murik_8 [283]

Answer:

The prices at which manager predict that at least 55 hats will be sold would be would be of $38

Step-by-step explanation:

According to the given data we the following:

Number of hats sold at $18=115

The manager predicts at 3 less will sold for every rise in 1 $ for at least 55 hats.

Therefore, reduction in number=115 hats-55 hats=60

So, increase in price=reduction in number/number of hats manager predicts that  will be sold for every $1 increase in price

increase in price=60/3=$20

Therefore, prices at which manager predict that at least 55 hats will be sold would be=$18+$20=$38

The prices at which manager predict that at least 55 hats will be sold would be would be of $38
