Answer:

2. yes; the equation can be written as y = kx; k = 1

Step-by-step explanation:

x-y = 0

That means x and y have to be the same value.

If you multiply a number by 1, you get the same thing.

If you multiply x by one, you get y (the same value).

Hope this helps!

Find X. Round to the nearest tenth if necessary.

storchak [24]

Answer:

3.2

Step-by-step explanation:

If there are 2 secont lines intersecting inside a circle like the picture shown, then the theorem tells us that "the product of 2 segments of one secant line is equal to the product of 2 segments of other secant line"

Thus, we can say that:

x * 10 = 8 * 4

10x = 32

x = 32/10

x = 3.2

Solve y = f(x) for x. Then find the input(s) when the output is 10.

elixir [45]

The inputs are 1 and -1 when the output is 2.

Step-by-step explanation:

The given function is

f(x) = 10 x²

Then we set y = f (x)

y = 10 x²

By dividing each side by 10 we get

x² = y/10

Then we solve for x

x = ± $\sqrt{y/2}$

Now we have to find the input(s) when the output is 10

x = ± $\sqrt{10/10}$

x = ± 1

Hence, the inputs are 1 and -1 when the output is 2.

The final solution is x =1 and x = -1.
