Which equation represents a line that passes through (-2, 4) and has a slope of 1/2?
jok3333 [9.3K]

Answer:

\large\boxed{y-4=\dfrac{1}{2}(x+2)\text{- point-slope form}}\\\boxed{y=\dfrac{1}{2}x+5\text{- slope-intercept form}}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

We have the slope m=\dfrac{1}{2} and the point (-2, 4).

Substitute:

y-4=\dfrac{1}{2}(x-(-2))

y-4=\dfrac{1}{2}(x+2) - point-slope form

Convert to the slope-intercept form (y = mx + b):

y-4=\dfrac{1}{2}(x+2)      <em>   use the distributive property</em>

y-4=\dfrac{1}{2}x+1         <em>add 4 to both sides</em>

y=\dfrac{1}{2}x+5 - slope-intercept form

Consider the function below. f(x) = 6x tan x, −π/2 &lt; x &lt; π/2 (a) find the vertical asymptote(s). (enter your answers as a
Molodets [167]

Answer: Does not exist.

Step-by-step explanation:

Since, given function,  f(x) = 6x tan x, where −π/2 < x < π/2.

⇒ f(x) = \frac{6x sin x}{cosx}

And, for vertical asymptote,  cosx= 0

⇒ x = π/2 + nπ where n is any integer.

But, for any n x is does not exist in the interval ( -π/2, π/2)

Therefore, vertical asymptote of f(x) where −π/2 < x < π/2 does not exist.

Can somebody help me please? Thank u! :)
tatuchka [14]

Answer:

1. last choice

2. first choice

Step-by-step explanation:

<h3><u>First</u><u> </u><u>Image</u></h3>

The reason why it is the last choice because when times keep going as distance also keeps increasing as well. But the last choice says that run at the end of track then turn around and run back. That means there must be a decreasing distance and a maximum value as well.

Therefore the only with max point/vertex is the absolute value which matches the last choice.

<h3><u>Second</u><u> </u><u>Image</u></h3>

First choice because the car straight forwards without any change. The car runs with a steady speed but the distance will keep changing without any change of distance.

So the answer is first choice.

F(x)=x2+8x+6. What is the value of f(4)?
dezoksy [38]
46

When it says f(4) that means x=4

So you then just fill in all the x’s with 4’s and solve as normal
