What is the distance between (22,-3) and (1, -3)?

Bingel [31]

Answer:

Option D

Step-by-step explanation:

<h2>Distance between two points</h2>

The y-value of the two points is unchanged. So, the line is parralel to x-axis.

The distance will be the diffrence between the x-co ordinates.

$\sf Distance = 1 - (-2\dfrac{1}{2})$

$\sf =1+\dfrac{5}{2}\\\\= \dfrac{2}{2}+\dfrac{5}{2}\\\\=\dfrac{7}{2}\\\\=3\dfrac{1}{2}$

What is the slope of a line that is perpendicular to the graphed line?

Lemur [1.5K]

Answer:

Step-by-step explanation:

To find the slope of the graphed line, you take two points. I have chosen (0, 4) and (8, 0)

The formula of a slope is (y value of second point $-y$ value of first point) divided by (x value of second point $-x$ value of first point):

$\frac{0-4}{8-0} =-\frac{1}{2}$

------------------------------------------------------------------------

The slope for a perpendicular line is 2.

What is the value of x in the equation 3.5x+5.4=19.4

kipiarov [429]

Answer: x = 4

Step-by-step explanation: To solve this equation, we could go right to our steps of subtracting 5.4 from both sides, but I would do a slightly different approach.

Since I hate working with decimals, I would get rid of them.

We can do this by multiplying both sides of the equation by 10, and remember to multiply every term by 10 to keep it balanced.

*Multiplying by 10 shifts the decimal point 1 place to the right

So we have 35x + 54 = 194 which looks a lot better.

Now subtract 54 from both sides to get 35x = 140.

Now divide both sides by 35 and x = 4.
