Write the equation of a line that is parallel to x

1 answer:

Answer:

x=-3

Step-by-step explanation:

Hi there!

<u>1) Determine the slope</u>

Parallel lines always have the same slope. However, the given line x=8 is a vertical line organized in the form x=d, where d is the x-intercept. Therefore, the slope is undefined, and our line will also have an undefined slope.

Now, because this line will also be a vertical line, it will also be organized like:

x=d

<u>2) Determine the x-intercept (d)</u>

Note that all the points a vertical line passes through will have the same x-coordinate. We're given that this line passes through the point (-3,-2), so therefore, the x-intercept will be (-3,0).

Plug this into x=d:

x=-3

I hope this helps!

Answer:

$f(g(5)) = 5$

$g(f(4)) = 0$

$f(f(6))=1$

$g(g(9)) = 0$

Step-by-step explanation:

Given

The attached table of values

Solving (a): f(g(5))

First, we solve for g(5)

$g(5) = 7$

So:

$f(g(5)) = f(7)$

Next, we solve for f(7).

From the table

$f(7) = 5$

So:

$f(g(5)) = 5$

Solving (b): g(f(4))

First, we solve for f(4)

$f(4) = 6$

So:

$g(f(4)) = g(6)$

Next, we solve for g(6).

From the table

$g(6) = 0$

So:

$g(f(4)) = 0$

Solving (c): f(f(6))

First, we solve for f(6)

$f(6) = 8$

So:

$f(f(6)) = f(8)$

Next, we solve for f(8).

From the table

$f(8) = 1$

So:

$f(f(6))=1$

Solving (d): g(g(9))

First, we solve for g(9)

$g(9) = 6$

So:

$g(g(9)) = g(6)$

Next, we solve for g(6).

From the table

$g(6) = 0$

So:

$g(g(9)) = 0$

If BD = 4, AD = x-6, and CD = x, what is the length of CD?

emmainna [20.7K]

Answer:

The length of CD is 8 units

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

we know that

According to the Right Triangle Altitude Theorem,

$(BD)^2 = (AD)(CD)$

substitute the given values

$(4)^2 = (x-6)(x)$

$16=x^2-6x\\x^2-6x-16=0$

solve the quadratic equation by graphing

The solution is x=8 or x=-6

see the attached figure N 2

Discard the negative length.

therefore

The length of CD is 8 units
