4. What is the x-value of

Mathematics
1 answer:
Viefleur [7K]3 years ago
3 0

Answer:

B) 1

Step-by-step explanation:

Since we are using elimination, we can just cancel 2y and -2y. No need of multiplying anything if we are just looking for x.

We add the equations and get:

9x=9

Then divide and the final answer is:

x=1

Can somebody help me with this one. It says use the vertical line test to determine which graph represents a function
sineoko [7]

Answer:

Only option C shows a function

Step-by-step explanation:

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. This means that a vertical line made in the domain of the function can crosses the curve of the function only once. If it crosses the curve of the function more than once, then the curve is not a function.

In option A, a vertical line would cross two values, so it is not a function.

The curve of option B is a vertical line itself, so a vertical line would intersect an infinite amount of points; then it is not a function.

Option C is a function because a vertical line would only intersect the function's curve (which is a line) once.

Factorize completely <br> 81k^2 - m^2
Genrish500 [490]

81k^2 - m^2 factors to

(9k + m)(9k - m)

Prove this by FOILing.

First - 81k^2

Outer - (-9km)

Inner - 9km

Last - (-m^2)

Put it into equation form

81k^2 - 9km + 9km - m^2

And combine terms to get the original equation,

81k^2 - m^2.
