So the rule with 270° counterclockwise rotation is the same as 90° clockwise rotation: <u>(x,y) → (y,-x)</u>

Now applying this rule to this coordinate,<u> (-5,1) would become (1,5).</u>

When number can each term of the equation be multiplied by to eliminate the fractions before solving 6-3/4x+1/3=1/2x+5

PolarNik [594]

Answer:

Step-by-step explanation:

You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):

$4=2^2\\3=3\\2=2$

Therefore, we need to include a factor of 3, and two factors of 2 ( $2^2$ ) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.

Our LCD is = $3*2^2=13*4=12$

Is the function given by, f(x)={3x-2 if x≤3 , 10-x if x>3} continuous at x = 3?

Darya [45]

<h2>Answer:</h2>

yes

<h3>Step-by-step explanation:</h3>

This is a piecewise-defined function because it is defined by two or more equations over a specified domain is. The graph of this function is shown below. So this functions is continuous because its graph is a single unbroken curve. So the function is defined be the line 3x - 2 when x = 3 and the output here is y = 7
