Function A is a quadratic function with a vertex at (3, 4) and a leading coefficient of -1 Function B has the equation y = |x +

skad [1K]

With the information given, we deduce that the parabola is

$y=-(x-3)^2+4 = -(x^2-6x+9)+4 = -x^2+6x-5$

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

$y=x^2-6x+5$

And to shift down a function, you subtract the shift from the equation: the equation becomes

$y=x^2-6x+5-2=x^2-6x+3$

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

$|x+2|\mapsto -|x+2|\mapsto -|x+2|+3$

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

$y(0)=3$

For the other function, we have

$y(0)=-|2|+3=-2+3=1$

Mrsjones has 1 4/8 pizza left after giving some to Greg she had 7/8 left how much did Greg take

Bezzdna [24]

Answer:

5/8

Step-by-step explanation:

well we 1 14/8 so lets turn that to a whole number which is 12/8 (you multiply the denominator by 1 and add the 4)

12/8 - 7/8 = 5/8 ( since both denominators are the same numbers you can simply subtract the numerator )

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.
