7 0

Answer:

A) 2

Step-by-step explanation:

Start off with the given information. The question states that the x-int. is 4, so you should recognize that there is a point at (4,0). Plug the point into the equation.

k(4) + 2(0) + 8 = 0

Now simplify the equation.

4k + 0 + 8 = 0

Isolate the variable, make sure it's on its own side.

4k = 8

Now get the k by itself to solve the equation. Divide both sides by 4.

k = 2

What is an equation of the line that passes through the point (−4,3) and is perpendicular to the line 4x−3y=3
kodGreya [7K]

Answer:

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

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

rearrange 4x - 3y = 3 into this form

subtract 4x from both sides

- 3y = - 4x + 3 ( divide all terms by - 3 )

y = \frac{4}{3} x - 1 ← in slope- intercept form

with slope m = \frac{4}{3}

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{\frac{4}{3} } = - \frac{3}{4}

y = - \frac{3}{4} x + c ← is the partial equation

To find c substitute (- 4, 3) into the partial equation

3 = 3 + c ⇒ c = 3 - 3 = 0

y = - \frac{3}{4} x ← equation of line

Square Root Functions
bezimeni [28]

Answer:

y = √(x) + 4

Step-by-step explanation:

Note that the basic function and graph here are of y = √x.  The graph of this basic (parent) function has the same shape as the graph shown, EXCEPT that the graph of y = √x has been translated 4 units upward.

Now look at the given graph.  We want to find the function represented by this graph.  We note that the shape of the graph is exactly the same as that of the graph of y = √x, except that the latter graph has been shifted up 4 units.  

Thus, the parent function y = √x becomes y = √(x) + 4.

polet [3.4K]

Answer:

The correct answer is "B."

Step-by-step explanation:

The fixed amount is $5, and the fee is $3 because the fee is based on the distance traveled. For every mile the price goes up by $3. That means that you get a fixed amount charged at the beginning, which is $5. Then you get a fee for every mile driven which is $3 per mile.

The question is, "What is the fixed amount charged?" The fixed amount is $5 which is choice "B."
