Use the drop-down menus to complete the statements below to answer this question: Can you determine whether a system of linear e
Oksanka [162]
  • The coordinates of a point satisfies the equation of a line if the point lies on the line
  • If a single point satisfies the equations of two lines, the point is on both lines, so the lines will intersect at that point.
  • This means that each point where the two lines touch is a solution to the system of equations
  • This means that if you substitute the x and y values of the point for x and y in the equations, both equations will be true

<h2>Explanation:</h2>

You haven't given any option. However, I have tried to complete this question according to what we know about system of linear equations. Suppose you have the following system of two linear equations in two variables:

(1) \ y=3+2x \\ \\ (2) \ y=x

The fist equation is the blue one and the second equation is the red one. Both have been plotted in the first figure below. As you can see, (-3, -3) is the point of intersection and lies on both lines. So this point is a solution of the system of equation and we can also say that it touches both lines. On the other hand, if you substitute the x and y values of the point for x and y in the equations, both equations will be true, that is:

-3=3+2(-2) \therefore -3=-3 \ True! \\ \\ (2) \ -3=-3 \ True!

Also, you can have a system with infinitely many solutions as the following:

(1) \ y+2x=4\\ \\ (2) \ 2y+4x=8

Here, every point that is solution of the first equation is solution of the second one. That is because both equations are basically the same. If we divide eq (2) by 2, then we get eq (1).

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria. How many bacteria will there be on
spayn [35]

In this question, it is given that

A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.

And we have to find number of bacterias on day *.

For that we use the following formula

N(t) =N_{0} (1 +r)^t

N(0)= 420, r = 0.18 , and \ t = 8days

Substituting these values in the formula, we will get

N(8)= 420(1+0.18)^8&#10;\\&#10;N(8)=1579

THerefore on day 8, number of bacterias are 1579.
