If you vertically compress the absolute value parent function, F(x) = |x|, by
marshall27 [118]

The current function equation is  Y=1/3|x|

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

The meaning relative f(x) = is the absolute value and is weighted by a factor 3 vertically.

If a constant (say a) multiplies the function, the parent will be extended vertically.

We have below vertical extension and compression conditions.

A > 1 = > spread vertically

0 < < 1 = > compression vertically

Therefore we will subtract the entire feature by 1/3 for vertical compression by a factor of 3.

The equation for the current function is then Y=1/3|x|

Use the formula M = NPQ to solve for the following variables.
Oksanka [162]

Step-by-step explanation:

M=NPQ

m/pq=Npq/pq

pq is going to cancel, you left with N

N= m/pq

To solve for q, we have to make q the subject.

m = Npq

divide both sides of the equation by NP

M/NP= q

that's the answer

Out of 200 std in a class. 150 like math , 120 like nepali .if the number of std who like nepali only is one third of the std wh
hichkok12 [17]

<u>ANSWER:  </u>

70 students like both nepali and maths.

<u>SOLUTION: </u>

Given,out of 200 students in a class. 150 like math, 120 like nepali.

The number of students who like nepali only is one third of the students who like math .

We need to find how many likes both subjects.

Let, the number of students who like only nepali be x.

Then, x is one-third of students who like maths.

x = \frac{1}{3} \times students who like maths

\begin{array}{l}{x=\frac{1}{3} \times 150} \\\\ {x=\frac{150}{3}} \\\\ {x=50}\end{array}

Now, out of 120 students who like nepali, only 50 students like nepali alone, which means remaining students like both nepali and maths

Students who like both subjects = 120 – 50 = 70.

Hence,70 students like both nepali and maths.

What are the x- and y-intercepts of the function graphed below?*
My name is Ann [436]

Answer:

(3,0) and (0,6)

Step-by-step explanation:

(x,y) is the only way to make ordered pair.

The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).

Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.

So the answer is (3,0) and (0,6).
