Answer:

y = 5 - 3x

<u>making y the subject</u>:

3x + y = 5

y = 5 - 3x

changing sides, changes positive (+) sign to negative (-)

changing sides, changes negative (-) sign to positive (+)

Martin wants to use coordinate geometry to prove that the opposite sides of

romanna [79]

The correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

The formula utilised to find the distance between two points is;-

X = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

We have the coordinates of the point A = (0, 0) and D is (0, b).By applying the formula to find the distance between A and D.

AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

Therefore the correct answer is option A which is the distance between A and D will be AD = $\sqrt{(0-0)^2-(b-0)^2}=\sqrt{b^2}=b$ .

The probability density function f(x) of a random variable X that has a uniform distribution between a and b is:

Lunna [17]

The probability density function (pdf) is;

f(x)= $\frac{1}{b - a}$ for a ≤ x ≤ b.

while the mean is given as $\frac{a + b}{2}$

And the standard deviation given as $\sqrt{\frac{(b - a)^{2} }{12} }$

Find f (-3) if f(x) = x^2

xz_007 [3.2K]

Konichiwa~! My name is Zalgo and I am here to help you out today. If f were to equal -3, first we need to put -3 into the equation. It would look like "f(-3)=x^2". The answer to that equation is 9.

I hope that this helps! :T
