vodomira [7]3 years ago
3 0

Answer:

8

Step-by-step explanation:

\frac{x}{14}  =  \frac{40}{70}  \\ x =  \frac{40}{70}  \times 14 \\ x =  \frac{40}{10}  \times 2 \\ x = 4 \times 2 \\ x  = 8

Answer:

P\geq 26e^{-0.079t}

P\geq 2

Step-by-step explanation:

We are given that there is an exponential decay.

Also, the decrease is of constant rate 7.9% i.e. 0.079 each year.

Since, the initial amount of the species is atleast 26 million.

Thus, the inequality for the corresponding model will be, P\geq 26e^{-0.079t},

where t is the time period for the decay and P is the population.

Moreover, is is given that the population cannot be less than 2 million.

So, we get, P\geq 2.

Hence, the inequalities to determine the possible number of insects over time are given by,

P\geq 26e^{-0.079t}

P\geq 2.

Answer:  Graph D (bottom right corner)

======================================================

Explanation:

The equation y = 3x+3 is in slope intercept form y = mx+b

m = 3 = slope

b = 3 = y intercept

In this case, both the slope and y intercept are the same (though in general they tend not to be).

The positive slope value means the line goes uphill as you move from left to right. The positive y intercept means the diagonal line crosses the y axis somewhere above the horizontal x axis. Specifically, it crosses the y axis at y = 3

Graph D is the only graph that has such a line on it. Graphs A, B and C have the positive slope line where they have a negative y intercept, so we can rule them out.

You can use graphing tools such as Desmos or Geogebra to help confirm this answer. You could also make a table of values, and plot each point, to form the lines. Two points is the minimum amount needed to form any line.

Please help. I will give five stars and 10 points for correct answer with explanation.
anygoal [31]

Answer:

A: It has no solution

Step-by-step explanation:

1. 3/4z - 1/4z + 3 = 2/4z + 5

2. 2/4z +3 = 2/4z + 5

3. 3 = 5 (No solution because 3 can never be equal to 5)
