Find the equation of the line that passes through point (6, 1) with the x-intercept of 2.

34kurt

<u>Answer:</u>

○ $y = \frac{1}{4}x - \frac{1}{2}$

<u>Step-by-step explanation:</u>

To find the equation of the line, let's first consider the points whose coordinates we have been given:

• (6, 1)

• (2, 0).

The point (2, 0) is what is called the x-intercept, which is the point where the line crosses the x-axis. This means that at this point, the y-coordinate of the line is 0.

Next, let's calculate the slope (gradient) of the line using the formula:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

where:

m = gradient,

$(x_2, y_2)$ and $(x_1, x_2)$ = points on the line.

Using the formula:

$m = \frac{1 - 0}{6 - 2}$

⇒ $m =\bf \frac{1}{4}$

Finally, now that we have two points on the line as well as the line's slope, we can use the following formula to find the equation of the line:

$\boxed{y - y_1 = m(x - x_1)}$

You can use any of the points on the line as $y_1$ and $x_1$ .

Using (2, 0):

$y - 0 = \frac{1}{4}( x - 2)$

⇒ $y = \frac{1}{4}x - \frac{1}{2}$

Therefore the equation of the line is $y = \frac{1}{4}x - \frac{1}{2}$ .

Given the definitions of f(x) and g(x) below, find the value of (gof)(1).

Marrrta [24]

Answer:

$(g*f)(x) = 34$

Step-by-step explanation:

For sake of clarity, $(g * f)(x) = g(f(x))$

First, find $f(1)$

$f(1) = 2(1)^2 - 2(1) - 4\\f(1) = 2-2-4 \\f(1)=-4$

Then, take what you got for $f(1)$ and plug that into $g(x)$ . In this case, $f(1) = -4$

$g(-4) = -5(-4) + 14\\g(-4)= 20 + 14\\g(-4) = 34$
