Answer:

<h3>              a. the  vertex represents a minimum point</h3><h3>              b.  f(x) = (x + 5)² - 5</h3>

Step-by-step explanation:

a.

a = 1 > 0  ← that means the parabola opens up, so the vertex is minimum of the function

b.

  f(x)=x^2+10x+20\\\\f(x)=\underline{x^2+10x+25} - 25+20\\\\f(x)=(x+5)^2-5

ok so lets start of with the fact that the whole thing is 21 units.

So we do 21-9=12 so then we now know that the rectangle is 12 so then we do 12*8 units which is= 96 . Now the triangles. so the first one we know that its 8*3 and times it by 1/2 because two triangles is equal to a rectangle so the first triangle is 12 and now the second. its 9-3= 6 then its 6*8*1/2 which is equal to 24 so now the final answer is

96+12+24 which is equal to 132 so i'm guessing it 132 square units

Hi!

Given:

\frac{x}{-1} > -6

Multiply both sides by -1

x

<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>

<u>Now, for the graph:</u>

-------------------------------------------------------------------------------------------------------------

For < or > signs, it should be an open circle. For \leq or \geq signs, it should be closed.

Since x is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.

(looks like you were right!!)
