Answer:

C) Yes, there exists one output for every input.

Step-by-step explanation:

We are given a graph.

When we draw vertical line test, the line passes through the one only point of the graph.

Similarly, when we draw horizontal line test, the line passes through the one only point of the graph.

The graph hold true for both vertical line test and horizontal line test.

Therefore, it is an one-one function.

For every input, there exists an output.

Therefore, the answer is C) Yes, there exists one output for every input.

Answer:

yes

Step-by-step explanation:

The graph is of a function (one output for every input) that also passes the horizontal line test (one input for every output). Hence it is one-to-one.

For a function, the key for it being one-to-one is that it pass the horizontal line test.

Can someone please explain C-12=-4 to me

nlexa [21]

Answer:

C = 8

Step-by-step explanation:

So to get C by itself, we need to add 12 to both sides of the equation, which is the opposite of subtracting:

C - 12 = -4

C - 12 + 12 = -4 + 12

C = 8

Find the value of x 16 14 10 9

Montano1993 [528]

Answer:

x = 9

Step-by-step explanation:

create a ratio between the triangles:

x/6 = 12/8; cross multiply

72 = 8x; divide 8 on both sides

x = 9

Line A is represented by the following equation: x + y = 2

Orlov [11]

Answer:

$ax+ay=k; a\ne0, k\ne2a$ ; line D in the options.

Step-by-step explanation:

The set of equations has no solutions if the two lines are parallel. A quick way to create a parallel line is to solve for y, put it in slope-intercept form. Else, as long as the cofficient of x and y are in the same ratio (in this case 1:1), the two lines are parallel, you just have to be careful not to pick the same line again!

The condition $a\ne 0$ makes sure you are still getting lines (else you would get rid of both x and y); the condition $k\ne 2a$ makes sure you're not picking line A again, just written in a different form.

Now that we have the options:

A and C have a different ratio for the coefficient of x and y (2:1 and 1:2) so are not good.

Choice B is just a more complicated way to write the same line, you can see by dividing both sides by 2 and get back x+y=2.

Line D is correct.
