The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains

aniked [119]

Answer:

$y=-2x+13$

Step-by-step explanation:

Equation of the line CD is given as $y=-2x-2$

Slope of the line CD = -2

Slope of the line parallel to CD = -2

Equation of the line parallel to CD is given by $y=mx+c$

$y=-2x+c$

But this line passes through (4,5)

Substituting the values in the equation:

$5=-2*(4)+c$

=> $c=5+8=13$

So the overall equation of the parallel line is given by $y=-2x+13$

To ensure he never eats the whole cake, Bobby only decides to eat half of what’s left for each serving. If 2/3 of the cake are l

siniylev [52]

1st serving: 2/3 * 1/2 = 2/6 or 1/3
2nd serving: 1/3 * 1/2 = 1/6
3rd serving: 1/6 * 1/2 = 1/12
4th serving: 1/12 * 1/2 = 1/24
5th serving: 1/24 * 1/2 = 1/48

1/3 + 1/6 + 1/12 + 1/24 + 1/48
1/3 * 16/16 = 16/48
1/6 * 8/8 = 8/48
1/12 * 4/4 = 4/48
1/24 * 2/2 = 2/48
1/48 * 1/1 = 1/48

16/48 + 8/48 + 4/48 + 2/48 + 1/48 = 31/48

Bobby ate 31/48 of the cake in total.

Find functions f(x) and g(x) so the given function can be expressed as

Alchen [17]

Answer:

$f(x) = \frac{5}{x}$

$g(x) = x - 4$

Step-by-step explanation:

Composite function:

$h(x) = f(g(x)) = (f \circ g)(x)$

h(x) = 5/x-4

We have x on the denominator and not the numerator, so the outer function is given by:

$f(x) = \frac{5}{x}$

The denominator is x - 4, so this is the inner function, so:

$g(x) = x - 4$
