2x -3< -1 or -3x < -15
pogonyaev

Answer:

x<1 or x>5

Step-by-step explanation:

2x -3< -1 or -3x < -15

Solve them separately then put them back together

2x-3 < -1

Add 3 to each side

2x-3+3<-1+3

2x<2

Divide by 2

2x/2 <2/2

x<1

-3x < -15

Divide each side by -3, remembering to flip the inequality

-3x/3 > -15/-3

x>5

Put them back together

x<1 or x>5

(14x-13) (4x+13) (6x+2)
Diano4ka-milaya [45]

Answer:

x = 7.416666667

Set everything equal to 180 (the total # of degrees in a triangle)

180 = 14x-13 + 4x+13 + 6x+2

Combine the variables

180 = 24x - 13 + 13 + 2

Do the math

180 = 24x +2

178 = 24x

x = 7.416666667

During the exponential phase, E. coli bacteria in a culture increase in number at a rate proportional to the current population.
NikAS [45]

Answer:

  197.2 million

Step-by-step explanation:

The appropriate exponential equation for the population is ...

  p(t) = 172.0e^(0.019t)

Then we can compute for t=7.2:

  p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2

7.2 minutes from now, the population will be about 197.2 million.

___

For continuous growth (or continuous compounding), the exponential formula is ...

  f(t) = (value at t=0)×e^(rt)

where r is the growth rate in one unit of time, and t is the number of time periods.
