So would it be one solution, no solution or infinite solution?
frosja888 [35]

Answer:

No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true. ... Note that we have variables on both sides of the equation.

A bacteria culture starts with 1000 bacteria and the number doubles every 40 minutes. (a) find a formula for the number of bacte
vfiekz [6]

The formula for the number of bacteria at time t is 1000 x (2^t).

The number of bacteria after one hour is 2828

The number of minutes for there to be 50,000 bacteria is 324 minutes.

<h3>What is the number of bacteria after 1 hour?
</h3>

The exponential function that can be used to determine the number of bacteria with the passage of time is:

initial population x (rate of increase)^t

1000 x (2^t).

Population after 1 hour : 1000 x 2^(60/40) = 2828

Time when there would be 50,000 bacteria : In(FV / PV) / r

Where:

  • FV = future bacteria population = 50,000
  • PV = present bacteria population = 1000
  • r = rate of increase = 100%

In (50,000 / 1000)

In 50 / 1  = 3.91 hours x 60 = 324 minutes

Describe and correct the error in writing an equation of the line shown
igor_vitrenko [27]

Answer:

y = - \frac{3}{5} x + 4

Step-by-step explanation:

the student used the y- coordinates of the points in the wrong order.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (5, 1) ← 2 points on the line

m = \frac{1-4}{5-0} = \frac{-3}{5} = - \frac{3}{5}

the line crosses the y- axis at (0, 4 ) ⇒ c = 4

y = - \frac{3}{5} x + 4 ← equation of line
