Answer:

y= -1/2x

Step-by-step explanation:

y-y1/x-x1=y2-y1/x2-x1

y-1/x+2=-1/2

2y-2= -x-2

2y= -x-2+2

2y=-x

y=-1x/2„

MrRa [10]

Answer: B

Step-by-step explanation:

The second power basically means that you multiply the number by itself that many times depending on the power, and since it's 50^2, the answer is Caleb - 100 | Jenna - 2,500. (Tip: Just multiply 50 x 50)

The number of fish (f) in a fish tank increases when the number of algae blooms (a) decreases. Write the correct equation for th
Artyom0805 [142]

Answer:

  • f = -2/5a +14
  • 12.4 ≈ 12 fish for 4 algae blooms

Step-by-step explanation:

The 2-point form of the equation for a line is useful when you are given two points to work with:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

The independent variable (x) is apparently "algae blooms" and is to be represented by "a". The dependent variable (y) is "number of fish" and is to be represented by "f". So, we have ...

  f = (4 -10)/(25 -10)(a -10) +10

  f = -6/15(a -10) +10

  f = -2/5a +14 . . . an equation for the scenario

Four a=4, the fish population is predicted to be ...

  f = -2/5(4) +14 = 12.4

There will be about 12 fish when there are 4 algae blooms.

If there are 4 green jelly beans, 2 white jelly
KatRina [158]

Step-by-step explanation:

Number of green and white jelly beans

= Number of green + Number of white

= 4 + 2 = 6.

Probability = Number of green and white jelly beans / Total number of jelly beans * 100%

= 6 / (4 + 2 + 5) * 100% = 54.55%.
