Fofino [41]3 years ago
4 0

Answer:

3(x + 5)²

Step-by-step explanation:

3x² + 30x + 75

3[x² + 10x + 25]

3[x² + 5x + 5x + 25]

3[x(x + 5) + 5(x + 5)]

3[(x + 5)(x + 5)]

3(x + 5)²

What point is a solution to y&gt; 2x -1<br><br> A.(0,2)<br> B.(4,2)<br> C.(0,-10)<br> D.(4,1)
Tom [10]

Well, we need to consider the x and y coordinates of the giben points, and check wether the y coordinate is greater than twice the x coordinate minus 1 (i.e. 2x-1):

  • For the first point, the x coordinate is 0. So, 2x-1 = -1. The y coordinate is 2, and 2>-1. So, this point is a solution.
  • For the second point, the x coordinate is 4. So, 2x-1 = 7. The y coordinate is 2, and 2<7. So, this point is not a solution.
  • For the third point, the x coordinate is 0. So, 2x-1 = -1. The y coordinate is -10, and -10<-1. So, this point is not a solution.
  • For the fourth point, the x coordinate is 4. So, 2x-1 = 7. The y coordinate is 1, and 1<7. So, this point is not a solution.

One week Michael worked 40 hours and sold 2,870 worth of shoes if his employer paid him 12.50 per hour and 6% commission of all
liq [111]

Answer:

Money which Michael make in commission = 158.7

Step-by-step explanation:

Given that,

number of hours Michael worked in a week = 40 hours

total sale of the week = 2870

commission which Micheal will get on sale = 6% above 225sale

To find,

total money Michael make in commission in the week

Commission = (2870 - 225)*6%

Commission = (2870 - 225)*6/100

Commission = 2645 *6/100

Commission = 158.7

Total money Micheal make in a week = (40*12.50) + (158.7)

                                                                 = 658.7

Answer:

8a. 0 8b. -1/3

Step-by-step explanation:

slope formula: \frac{y_{2} - y_{1}}{x_{2} - x{1}}

8a. => (8 + 12)/(17 - 17) = 20/0 = 0

8b. (1 + 2)/(-3 - 6) = 3/-9 = - 1/3
