Which equation is in slope-intercept form and represents a line with slope 0 through the point (2, 3)?

alexandr1967 [171]

I think it would be b) because you're given a slope of 0, so that leaves you with
$y=0x+b$
, resulting into this
$y=b$
You'd be just left with a continuous horizontal line going through the y-axis of 3 since you're passing the point (2,3), where 3 represents the y-value when your slope is at 0.

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 for brainlest and 25 points

nordsb [41]

Answer:

Order from greatest to least: 10.5, $3\pi +1$ , $\sqrt{105}$

Step-by-step explanation:

step 1 simplify each number

3π + 1 = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

$\sqrt{105} =10.2469507$

*round to the nearest tenth*

$\sqrt{105} =10.2$

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = $\sqrt{105}$

Your answer is

10.5 , 3 $\pi$ + 1, $\sqrt{105}$
