PLZ HELP IDK WHAT THIS MEANS
Hoochie [10]

Answer: Option B.

Step-by-step explanation:

In the graph we can see the graph of a quadratic equation (from this we could conclude that the graph will not change the current direction for the arms, so the arms will keep going down), and we also can see that as x increases in absolute value, the value of y decreases.

Then we could conclude that as IxI is really big, we will have that f(x) goes to minus infinity

x -->∞, f(x) --> -∞

x--> -∞, f(x) --> -∞

Then the correct option is B

Answer:

The correct answer is: {2,4,6,8}

Step-by-step explanation:

Given sets are:

P = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and V= {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

We have to find

P∩V

The symbol is used for intersection of two sets. In intersection, only common elements of both sets are written in result.

So,

P∩V = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9) ∩ {2, 4, 6, 8, 10, 12, 14, 16, 18, 20)

P∩V = {2,4,6,8}

Hence,

The correct answer is: {2,4,6,8}

What is greater 5/6 7/12 or 7/10
algol [13]
5/6
you can do 2 things here
use a calculator and divide the numerator by the denominator
or the method you're probably meant to use
change each fraction so they all have the same denominator
the common denominator in this case would be 60
5/6*10=50/60
7/12*5=35/60
7/10*6=42/60
the number with the highest numerator would be the larger fraction
in this case, being 50/60 or 5/6

SAM ≅ ΔZYX , <br> Options:<br> M = 36<br><br> M = 60<br><br> M = 84<br><br> M = 102
Reil [10]

Answer:

<u>M = 36</u>

Step-by-step explanation:

Since SAM = ZYX

We can assume that all angles on SAM will equal the same as ZYX.

There are 180° total in a triangle, so you add 60 + 84, which equals 144, then you subtract 144 from 180 to find the remaining angle.

Therefore M = 36°
