Based on the graph below, what is yhe total number of solutions to the equation f(x)= g(x)?

valentinak56 [21]

Answer:

Based on the graph below, what is the total number of solutions to the equation f(x)= g(x) will be 3.

Step-by-step explanation:

The intersection points of both graphs would be the total number of solutions to the equation f(x)= g(x).

From the given diagram, it is clear that both the graphs intersect at three locations points or intersection points. The approximations locations of The intersection points of both graphs are

(1.5, 4.125)

(-1, 0), and

(-2.5, -3.5)

Therefore, based on the graph below, what is the total number of solutions to the equation f(x)= g(x) will be 3.

4x + 5y = 10

Vika [28.1K]

Answer:

For A = 32/5 and B = 8 the system of equations will have infinitely many solutions.

Step-by-step explanation:

Given equations are:

4x + 5y = 10

Ax + By = 16

The general form of linear equation in two variables is given by:

$ax+by = c$

Here a, b and c are constants and x,y are variables.

In the given equations, after comparing with the general form

$a_1 = 4\\b_1 = 5 \\c_1 = 10\\a_2 = A\\b_2 =B\\c_2 = 16$

"In order for a system of equations to have infinity many solutions,

$\frac{a_1}{a_2} = \frac{b_1}{b_2} = \frac{c_1}{c_2}$ "

Putting the values we get

$\frac{4}{A} = \frac{5}{B} = \frac{10}{16}\\\frac{4}{A} = \frac{5}{B} = \frac{5}{8}\\Now\\\frac{4}{A} = \frac{5}{8}\\\frac{A}{4} = \frac{8}{5}\\A = \frac{8}{5} * 4\\A = \frac{32}{5}\\And\\\frac{5}{B} = \frac{5}{8}\\\frac{B}{5} = \frac{8}{5}\\B = 8$

Hence,

For A = 32/5 and B = 8 the system of equations will have infinitely many solutions.

Answer:

3125 bacteria.

Step-by-step explanation:

We can write an exponential function to represent the situation.

We know that the current population is 100,000.

The population doubles each day.

The standard exponential function is given by:

$P(t)=a(r)^t$

Since our current population is 100,000, a = 100000.

Since our rate is doubling, r = 2.

So:

$P(t)=100000(2)^t$

We want to find the population five days ago.

So, we can say that t = -5. The negative represent the number of days that has passed.

Therefore:

$\displaystyle P(-5)=100000(2)^{-5} = 100000 \Big( \frac{1}{32}\Big) = 3125 \text{ bacteria}$

However, we dealing within this context, we really can't have negative days. Although it works in this case, it can cause some confusion. So, let's write a function based on the original population.

We know that the bacterial population had been doubling for 5 days. Let A represent the initial population. So, our function is:

$P(t)=A(2)^t$
