Answer:

Matt should have factored out the leading coefficient 2 on the second step before completing the square

Step-by-step explanation:

To complete the square, you must first factor the leading coefficient from the first two terms.

y = 2x² − 10x − 4

y = 2 (x² − 5x) − 4

y = 2 (x² − 5x + 25/4 − 25/4) − 4

y = 2 (x² − 5x + 25/4) − 25/2 − 4

y = 2 (x − 5/2)² − 33/4

Pls I need help with his math problem

Answer:

  a) P = 0.08s +200

  b) $488

  c) $6250

Step-by-step explanation:

<h3>a)</h3>

Your answer is correct. The commission rate is multiplied by the sales amount, and that product is added to the guaranteed pay to get the paycheck amount:

  P = 0.08s +200

__

<h3>b)</h3>

Fill in 3600 for s and do the arithmetic.

  P = 0.08×3600 +200 = 288 +200 = 488

The paycheck amount will be $488.

__

<h3>c)</h3>

Use the equation for part (a) and solve for P = 700.

  700 = 0.08s +200

  500 = 0.08s . . . . . . subtract 200

  500/0.08 = s = 6250 . . . dollars; divide by the coefficient of s to get this

Sales would have to be $6250.

There are 12 boys and 16 girls in a classroom. Which represents the simplified ratio of girls to students in the classroom?
dedylja [7]

We know that there are 16 girls. That is the first part of the ratio. Now, it says girls to students, which mean you have to add up the total of girls and boys together. 12+16=28. There are 28 students in total. Now, you have the ratio of 16:28. But, it says simplified...so we need to divide both sides of the ratio by a number. Let's choose 4 because 4 can go both into 16 and 28. 16/4=4. 28/4=7. So, the simplified ratio of girls to students in the classroom is 4:7.

Hope this helped!
