graph each inequality y-3x<-4
First we solve the inequality for y
Add 3x on both sides, so inequality becomes
y < 3x -4
Now we graph it
for graphing , replace < symbol with = sign
y= 3x - 4
Now make a table, assume some number for x and find out y
x y
-1 y=3(-1)-4 = -7
0 y=3(0)-4 = -4
1 y=3(1)-4 = -1
Now plot (-1,-7), (0,-4) ,(1,-1) on graph
Join all the points and make a dotted line ( dotted line for < or > symbol)
now we do shading
for < symbol we shade down
for > symbol we shade up
The graph is attached below

Answer:
AB = 4.5 units
Step-by-step explanation:
Let the length of AB be x.
<em><u>GIVEN</u></em><em> :-</em>
- BC = 3 units
- CD = 4 units
- ED = 6 units
- BD || AE
<em><u>TO FIND</u></em><em> :-</em>
<em><u>FACTS TO KNOW BEFORE SOLVING</u></em><em> :-</em>
<em><u>Basic Proportionality Theorem</u></em> :-
- If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points , the other two sides are divided in the same ratio.
<em><u>PROCEDURE</u></em><em> :-</em>
According to Basic Proportionality Theorem ,
∴ AB = 4.5 units
formula for interior angles of a polygon is 180 times the number of sides minus 2
20 a 20gon has 20 sides, 20 -2 = 18, 180*18 = 3240
sum of interior angles = 3240 degrees
