A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol
mestny [16]
Let N be the number of items sold and p the price. 
Since the variation is inverse, then the relation between N and p is:
N=k\dfrac{1}{p}
For N=20000 and p = $9.5, we get the formula:
 20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000
If p = 8.75, then the number of items sold can be computed using the formula:
N= 190000\dfrac{1}{8.75}=21714 \text{ total items}

On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3). Which point could
Fynjy0 [20]

MN goes through

  • (2,3)
  • (-3,2)

Slope:-

  • m=2-3/-3-2=-1/-5=1/5

Slope of perpendicular line:-

  • -5

Passes through k(3,-3)

Equation in point slope form

  • y-y1=m(x-x1)
  • y+3=-5(x-3)
  • y+3=-5x+15
  • y=-5x+12

Check one by one

  • 0=-5(-12)+12=60+12=72
  • 2=-5(2)+12=-10+12=2

Yes option B is correct

juin [17]

Distribute the -9 into the values in the parentheses.

STEP BY STEP

-9(-2x-3)

-9*-2x=18x

-9*-3=27

Therefore, the equation then becomes: 18x+27.

The answer is the first choice, or A.
