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

Maymona book club is ordering new novels, She knows that the total cost of 6 books is $90, and 10 books cost $150. Write an equa
aleksandr82 [10.1K]

Answer:

Y=15x

Step-by-step explanation:

<h2>Okay so let's approach this problem!</h2><h2 />

X is books and Y is total cost

Let's find the slope!

Y2-Y1/ X2-X1

Just replace

\frac{150 - 90}{10 - 6}

\frac{60}{4}  = 15

The slope is 15

y = 15x + b

Now replace x and y with coordinates and solve

150 = 15(10) + b \\ 150 = 150 + b \\  - 150 \\ 0 = b

The final equation:

y = 15x

That's it! If you have any questions please ask! Brainliest Appreciated.
