Which ordered pairs are in the solution set of the system of linear inequalities?

Thought Process:

The solution to this can be found through plotting both of these functions and shading each region above or below the lines (as per the greater and less than signs given)

the region that overlaps both of the above shaded region is the solution set for all ordered pairs that satisfy the two inequalities.

Solution:

let's start by plotting

y > -\dfrac{1}{3}x + 2

it's the same as plotting y = -\dfrac{1}{3}x + 2, but '>' sign suggests to shade everything above this line.

<u>side note:</u>

'>' excludes every ordered pair in the line,

'\leq' includes every ordered pair in the line,

coming back to our solution:

now let's plot the other equation

y > 2x + 3

it's the same as plotting  y = 2x + 3, but '<' sign suggests to shade the area below this line.

The solution set is the area that is overlapped by the two shaded regions.

So every ordered pair (or coordinate (x,y)) that lies within this overlapped shaded region, excluding the points that lie on the lines themselves, satisfy the given two inequalities

Answer:

  1/(t+4)²

Step-by-step explanation:

  \dfrac{t+3}{t+4}\div(t^2+7t+12)=\dfrac{t+3}{t+4}\cdot\dfrac{1}{(t+3)(t+4)}=\dfrac{(t+3)}{(t+3)(t+4)^2}\\\\=\boxed{\dfrac{1}{(t+4)^2}}

Geometry question please help meeee
garik1379 [7]
Answers:
Scale factor is 8:5
Area ratio is 64:25
Volume ratio is 512:125

=================================================

Explanation:

Divide the second surface area (375) over the first surface area (960) to get
375/960 = 0.390625
Then take the square root of this to get
sqrt(0.390625) = 0.625
The decimal value 0.625 converts to the fraction 5/8, which turns into the scale factor 8:5 

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

Once you know the scale factor, you can square both sides to get the area ratio
8:5
8^2:5^2
64:25

The area ratio is 64:25

Then go back to the scale factor, and cube each part to get the volume ratio
8:5
8^3:5^3
512:125

The volume ratio is 512:125

What is the difference between ordering numbers, comparing numbers, and comparing amounts?
labwork [276]

Answer:

different definitions

Step-by-step explanation:

ordering numbers can be seen as arranging the numbers by a certain characteristics. for example, you could order numbers from least to greatest

comparing numbers can be seen as looking into two or more numbers rather than the entire group of numbers. for example, if there were the numbers 1, 2, 3, 4, 5, 6, you could say that 2, 4, 6, are even numbers

comparing amounts could be determined by worth but not the numerical values. for example, you could have a gallon of milk and a quart of orange juice but just by the size of the container, a gallon of milk is bigger and holds more than a quart of orange juice
