Billie Holiday sells children's clothing for Sara Vaughn's Toddler Shop. Baby blankets sell for $29.99 after a markup rate based

Mariulka [41]

Answer:

Cost: $14.349

Markup: $15.649

Step-by-step explanation:

1. Rewrite the percent as decimal. Divide it by 100, as following:

109/100=1.09

3. Now, knowing that Baby blankets sell for $29.99 after a markup rate based on cost of 109%, you can write the following expresion:

$x+1.09x=29.99$

Where x is the cost.

4. You must solve for x, then, you obtain:

$2.09x=29.99\\x=\frac{29.99}{2.09}\\x=14.349$

5. The markup is:

$M=29.99-14.349=15.649$

What is y=4x^2-9x+1 in vertex form

Anna11 [10]

Answer:

$y = 4 \left(x - \dfrac{9}{8} \right)^2 - \dfrac{65}{16}$

Step-by-step explanation:

$y = 4x^2 - 9x + 1$

You need to complete the square on the right side.

$y = (4x^2 - 9x) + 1$

$y = 4(x^2 - \dfrac{9}{4}x) + 1$

$y = 4 \left( x^2 - \dfrac{9}{4}x + \left( \dfrac{9}{8} \right)^2 \right) + 1 - 4\left( \dfrac{9}{8} \right)^2$

$y = 4 \left(x - \dfrac{9}{8} \right)^2 + 1 - 4 \left( \dfrac{81}{64} \right)$

$y = 4 \left(x - \dfrac{9}{8} \right)^2 + 1 - \dfrac{81}{16}$

$y = 4 \left(x - \dfrac{9}{8} \right)^2 + \dfrac{16}{16} - \dfrac{81}{16}$

$y = 4 \left(x - \dfrac{9}{8} \right)^2 - \dfrac{65}{16}$
