If f(x) = 7 + 4x and g (x) = StartFraction 1 Over 2 x EndFraction, what is the value of (StartFraction f Over g EndFraction) (5)

Degger [83]

Answer:

$\frac{f}{g}(5)$ = 270 ⇒ Last answer

Step-by-step explanation:

* If f(x) = 7 + 4x

* If g(x) = $\frac{1}{2x}$

* We want to find $\frac{f}{g}(5)$

- Lets find at first $\frac{f}{g}(x)$

∵ f(x) = 7 + 4x

∵ g(x) = $\frac{1}{2x}$

∴ $\frac{f}{g}(x)=\frac{7+4x}{\frac{1}{2x}}$

- Lets divide the numerator by the denominator

∵ The numerator is 7 + 4x

∵ The denominator is $\frac{1}{2x}$

∴ (7 + 4x) ÷ $\frac{1}{2x}$

- Lets reverse the division sign to multiplication sign and reciprocal

the fraction after the division sign

∴ (7 + 4x) × $\frac{2x}{1}$

∴ $\frac{f}{g}(x)$ = 2x(7 + 4x)

∴ $\frac{f}{g}(x)$ = 14x + 8x²

- Now substitute x by 5

∴ $\frac{f}{g}(5)$ = 14(5) + 8(5)² = 70 + 200 = 270

∴ $\frac{f}{g}(5)$ = 270

Answer:

$y = \frac{4}{3}x - 13$

Step-by-step explanation:

The equation for a line in slope-intercept form is $y=mx+b$ , where $m$ is the slope and $b$ is the y-intercept. This means that the slope of $y = \frac{4}{3}x + 5$ is 4/3.

We would like to find a line parallel to $y = \frac{4}{3}x + 5$ which passes through the point (12, 3). Any parallel line must have the same slope, so the equation for the new line will be $y = \frac{4}{3}x + b$ for some number $b$ . We know that $y$ must be equal to 3 when $x$ is equal to 12, so 3 = (4/3)(12) + b. This means that 3 = 16 + b, so b = -13.
