Is the following statement correct? Explain.

Maksim231197 [3]

Answer: The answer is NO.

Step-by-step explanation: The given statement is -

If the graph of two equations are coincident lines, then that system of equations will have no solution.

We are to check whether the above statement is correct or not.

Any two equations having graphs as coincident lines are of the form -

$ax+by=c,\\\\dax+dby=dc,\\\\\textup{where}~~d\neq 1.$

If we take d = 1, then both the equations will be same.

Now, subtracting the second equation from first, we have

$a(1-d)x+b(1-d)y=c(1-d)\\\\\Rightarrow ax+by=c,~\textup{since}~d\neq 1,~\textup{so}~1-d\neq 0.$

Again, we will get the first equation, which is linear in two unknown variables. So, the system will have infinite number of solutions, which consists of the points lying on the line.

For example, see the attached figure, the graphs of following two equations is drawn and they are coincident. Also, the result is again the same straight line which has infinite number of points on it. These points makes the solution for the following system.

$2x+5y=10,\\\\6x+15y=30.$

Thus, the given statement is not correct.

About 7/10 of the surface of the earth is covered with water. Express this as an equivalent fraction with 100 as the denominator

larisa [96]

Answer:

70/100

Step-by-step explanation:

Surface of the earth covered with water = 7/10

Equivalent fraction of 7/10 with 100 as the denominator = 70/100

This means 70% of the earth surface is covered with water

Percentage covered with land = Total percentage - percentage covered with water

= 100/100 - 70/100

= 100-70/100

= 30/100

Percentage covered with land = 30%

One root of a third degree polynomial function f(x) is –5 + 2i. Which statement describes the number and nature of all roots for

zheka24 [161]

Given the root of -5+2i, we are asked to describe the best statement that describes the polynomial. The root -5+2i cannot exist without its conjugate root, -5-2i. Complex roots are always accompanied by at least 1 real root. Since there are only 3 roots, there should be one root only, hence the answer is B.<span>
