It is the top left graph

I can tell because at 0 hours, they started out with 24 plants, which means there should be a point at (0,24). I also know that free every hour, they remove 3 plants, so the line should be going down (as the number of pots keeps on getting lower).

Answer:

1st graph

Step-by-step explanation:

this is the only graph that begins at 24, has a negative slope, is linear, and ends at (8,0) which, after 8 hours losing 3 pots per hour, makes sense

13. Given that y varies as x^2 and that y = 36 when x=3, find:

saw5 [17]

Answer:

K=4

Y=16

X=4

Step-by-step explanation:

$y = kx {}^{2} \\ finding \: k \: when \: y= 36 \: and \: x = 3 \\ 36 = k(3) {}^{2} \\ 36 = 9k \\ dividing \: through \: by \: 9 \\ \frac{36}{9} = \frac{9k}{9} \\ 4 = k \\ k = 4 \\ findnig \: y \: when \: x = 2 \\ y = 4(2) {}^{2} \\ y = 4 \times 4 = 16 \\ finding \: x \: when \: y = 64 \\ 64 = 4 \times x \\ 64 = 4x \\ dividing \: through \: by \: 4 \\ \frac{64}{4} = \frac{4x {}^{2} }{4} \\ 16 = x {}^{2} \\ square \: root \: bothsides \\ \sqrt{16} = x {}^{2} \\ 4 = x \\ x = 4$

The diffrence between the roots of the equation 2x^2-5x+c=0 is 0.25 find c

kumpel [21]

Answer:

c = 3.09375

Step-by-step explanation:

Standard for of quadratic equation:

ax² + bx + c = 0

We have

2x² - 5x + c = 0

Sum of the roots

x₁ + x₂ = - b/a = -(-5)/2 = 2.5

Product of the roots

x₁x₂ = c/a = c / 2

We have:

x₁ - x₂ = 0.25

The square of the above is:

(x₁ - x₂)² = (x₁ + x₂)² - 4x₁x₂

Substitute known values and solve for c:

0.25² = (2.5)² - 4(c/2)
2c = 6.25 - 0.0625
2c = 6.1875
c = 3.09375

(4,7) and (5,1) as an equation

monitta

Answer:

y = -6x + 31

Step-by-step explanation:

In order for us to make this an equation of the form y = mx + b we have to find the slope.

The formula for slope is rise/ run. The rise is 6 and the run is -1.

So, the slope is 6/-1 or -6.

Our equation is now: y = -6x + b

Substituting 4,7 into the equation we get 7 = -24 + b

So, b = 31.

To check out answers we substitute 5,1 in and it works.
