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

Mathematics

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

21. In the figure given below, AC is parallel to DE. Find the valuesof xy and z and hence find the 2DBE.
algol13

Answer:

X= 50°

Y= 70°

Z= 30°

BDE= 30°

2BDE= 60°

Step-by-step explanation:

(2x -70 )+z+(2x+20)=180...(sum of angle on a straight line)

2x -70 = BDE... alternate angles

Y + (2x-70)+(50+x-20) = 180...(sum of angles in a triangle)

X-20 = z ... alternate and opposite angles

(2x -70 )+z+(2x-+20)=180

2x-70 + x-20 +2x +20= 180

5x -70= 180

5x = 250

X= 50°

X-20 = z

50-20= z

30° = z

2x -70 = BDE

2(50) -70 = BDE

100-70 = BDE

30°= BDE

Y + (2x-70)+(50+x-20)

Y + 100-70 +50 +50 -20 = 180

Y + 200-90=180

Y= 70°

2BDE = 2*30

2BDE= 60°

{1/8, -0.02555,0.2,-1/7} following set up numbers from least to greatest by the way there are two negatives
nata0808 [166]

Change each of the fractions into decimals.

1/8 becomes 0.125

-1/7 becomes -0.143

and -0.02555

0.2

In order from least to greatest,

-0.143, -0.02555, 0.125, 0.2

OR

-1/7, -0.02555, 1/8 and 0.2

Pls Help Choose the correct word to complete the statement: If BC intersects circle A only at point B, and mCBA = 90°, then CB i
cricket20 [7]

Line CB touches circle A only at one point (point B), hence CB is a tangent.

<h3>What is a circle?</h3>

A circle is the locus of a point such that its distance from a fixed point (center) is always constant.

When a line intersects a circle in exactly one point the line is said to be tangent to the circle

Hence since Line CB touches circle A only at one point (point B), hence CB is a tangent.
