Explain why x^2 = -81 does not have a solution.

1 answer:

6 0

Remember, the graph of a line represents every point that is a possible solution for the equation of that line. So when the graphs of two equations cross, the point of intersection lies on both lines, meaning that it is a possible solution for both equations. When the graphs of two equations never touch, there are no shared points and there are no possible solutions for the system. When the graphs of two equations lie on top of one another, they share all their points and every one is a possible solution.

Is 8,749,628 divisible by 8? Help me plz

CaHeK987 [17]

Answer:

so yes

Step-by-step explanation:

If you can divide two numbers without a remainder, then the first number is divisible by the second.

For example, 12 is divisible by 2.

12÷2=6

But 12 is not divisible by 5. When you divide 12 by 5, you get a remainder.

12÷5=2 R2

This table gives a few (x,y) pairs of a line in the coordinate plane

blagie [28]

Answer:

The x-intercept of the line is the point (12,0)

Step-by-step explanation:

step 1

Find the slope of the lime

Take the points

(22,36) and (32,72)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{72-36}{32-22}$

$m=\frac{36}{10}$

$m=3.6$

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=3.6$

$point (22,36)$

substitute

$y-36=3.6(x-22)$

step 3

Find the x-intercept

we know that

The x-intercept of a line is the value of x when the value of y is equal to zero

For y=0

substitute in the equation and solve for x

$0-36=3.6(x-22)$

$0-36=3.6x-79.2$

$3.6x=79.2-36$

$3.6x=43.2$

$x=12$

therefore

The x-intercept of the line is the point (12,0)

Does the following infinite series converge or diverge? explain your answer. 7+28+112+448+...

makvit [3.9K]

Infinite series can either be convergent or divergent. It is convergent if the series has a limit and would approach a certain real number. It is divergent if it has no limits.

The given above is a series that is comprised of whole numbers and can go as large as the positive infinity. Because of this, the answer to this item is Divergent.
