Answer:
C. 13
Step-by-step explanation:
Answer:
The answer is C, y = 1/4x - 4
Step-by-step explanation:
First, we have to find the slope of the perpendicular line, and to do so you must take the slope of the given line and opposite reciprocate it.
To do so, you first reciprocate the slope by flipping the numerator and denominator which now makes -4 into -1/4.
Then we have to make it the opposite value, like making a negative into a positive or a positive into a negative. In this case you make -1/4 into a positive 1/4.
We now have the slope of the perpendicular line and can make out answer choices A and B. Which now leaves us with C and D.
The line must go through the point (4, -3). To do that we must adjust the y-intercept until it goes though that point.
We get the y-intercept of -4 and the line that has the y-intercept of -4 and the slope of 1/4 is C.
You answer is C, y = 1/4x - 4.

Answer:
The diagonal is irrational because it is a product of a rational and an irrational number
Step-by-step explanation:
The options are not given. However, the question is still answerable.
Given
Shape: Square
Length: Rational
Since the side length is said to be rational, I'll answer the question based on whether the diagonal is rational or not.
Having said that:
The diagonal (d) of a square with side length (l) is calculated using Pythagoras theorem.
Take positive square root of both sides
Split:
Recall that the side length (l) is rational.
However, is irrational.
So, the product of l and will be irrational
Hence:
The diagonal is irrational
The answer to ur question is c (i think)
