In synthetic division, you start by bringing down the first 1 in the box.  Multiply that by the 1 outside the box and get a 1.  Put that new 1 under the 2 inside the box and add to get 3.  Multiply the  outside the box by that 3 to get 3 and put that new 3 under the -3 in the box and add to get 0.  Multiply that 0 by the 1 outside the box to get 0.  Put that 0 under the 2 and add to get the remainder of 2.  Your answer is 2, C.

What best describes the expression y over 7? 7 times some number Some number minus 7 7 more than some number Some number divided
marysya [2.9K]
"Over" usually means divide. First hint, check.

If we write it out, it looks like this:

\frac{y}{7}

This is the same as <em>some number divided by 7.</em>

Margaret is saving money for her summer vacation. She calculates that her starting amount is 0.4% of the total amount she wants
garri49 [273]

0.4% can be written as 0.004 in decimal.

Step-by-step explanation:

Let the total amount she wants to save be 'a'

Starting amount = 0.4% of the total amount

= 0.4% of a

= (0.4/100) a

0.4% = 0.4/100

= 0.004

0.4% can be written as 0.004 in decimal.

The graph of a quadratic function has roots at -3 and -7 and a vertex at (-5, 4). What is the equation of the function in vertex
melomori [17]

Answer:

y = -(x + 5)² + 4

Step-by-step explanation:

The roots are -3 and -7, so:

y = a (x + 3) (x + 7)

Distribute and complete the square:

y = a (x² + 10x + 21)

y = a (x² + 10x + 25 − 4)

y = a (x² + 10x + 25) − 4a

y = a (x + 5)² − 4a

The vertex is (-5, 4), so a = -1.

y = -(x + 5)² + 4
