what is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?

yaroslaw [1]

Answer:

y = 4/3x - 6

Step-by-step explanation:

The slope of the 1st line is -3/4

So for the perpendicular line it has to be the exact opposite.

That looks like this ---> 4/3x

And the y-intercept is -6 because if you make a straight line where the x intercept is it matches.

The equation would look like this

y = 4/3x - 6

Hope this helps! Have a blessed day!

Use the roster method to write each of the given sets. (Enter EMPTY for the empty set.)

Kitty [74]

Answer:

a) Empty set

b) $\{x : x \in N \text{ and } x < 13\}$

Step-by-step explanation:

Roster form is a comma separated list form of set.

a) The set of natural numbers x that satisfy x + 4 = 1.

$x + 4 = 1\\x = -3 \notin N$

Thus, x is an empty set.

b) set-builder notation for the set {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

We use x to represent this set. Now x belongs to natural number and is less than equal to 12.

Thus, it can be written as:

$\{x : x \in N \text{ and } x < 13\}$

A school principal estimates that no more than 6% of this years senior class will graduate with honors. There are 350 students.

vovikov84 [41]

<span>Given there is no more of 6% of students graduates with honors, and there is a total of 350 senior class students. All you have to do is multiply 350 to 6% or simply get 6% from 350.
To get the answer: 350 students * .06 = 21 students.
Therefore, no more than 21 students will graduate with honors in the senior class batch.</span>
