Which equation shows the point slope form of the line the glasses through (3,2) and has a slope of 1/3
7nadin3 [17]

B

The equation of a line in ' point- slope form ' is

y - b = m( x - a )

where m is the slope and (a, b ) a point on the line

here m = \frac{1}{3} and (a, b ) = (3, 2 )

y - 2 = \frac{1}{3} ( x - 3 ) → in point- slope form

You have $50
Yakvenalex [24]

50+5x=total profit. To get 10% of 50 you would multiply .1x50= 5. X would be the amount of days past so 10th day = $100 total but $50 profit and 30th day = $200 total but $150 profit

What is the value of the expression |a + b| + |c| when a = –3, b = 7, and c = –15?
nikdorinn [45]
We know:
|a|=  \left\{\begin{array}{ccc}a&if\ a \ \textgreater \  0\\0&if\ a=0\\-a&if\ a \ \textless \  0\end{array}\right\\\\|2|=2\\|0|=0\\|-3|=3

|a+b|+|c|
substitute a = -3; b = 7; c = -15
|-3+7|+|-15|=|4|+15=4+15=19

PLEASE HELP QUICK :) multiple choice.
Damm [24]

Answer:

  • C. f(x) = x³ + 10x² + 7x - 18

Step-by-step explanation:

If the function has a factor of x + 9, then the function will have a zero output at x = -9

<u>Lets verify:</u>

  • A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
  • B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 =  -9, No
  • C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
  • D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No
