Part A
To graph this, we plot open holes at -2 and 3 on the number line. Shade between these open holes to represent values between -2 and 3, but we don't include the endpoints.
See figure 1 below.
===============================================
Part B
Solve the first inequality to get
Now solve the second inequality
We have 
The graph will have an open hole at -3 and a closed/filled in circle at 1. We shade everywhere but the region between these marked values. The left portion in blue represents stuff smaller than -3; the right portion in red represents values equal to 1 or larger.
See figure 2 below.
Answer: it's da probability dat u'll get a total factor of 20. I hope dis helps or at least a little bit :3
Step-by-step explanation:
Rent = 360
Groceries and hhold goods = 240
Given:
Weekly pay = 720
Groceries and household goods = 1/3 of weekly pay
Rent = 3/4 of money net from groceries.
720 * 1/3 = (720*1)/3 = 240 groceries and household goods
720 - 240 = 480 remaining money for rent
480 * 3/4 = (480*3)/4 = 1440/4 = 360 rental payment
480 - 360 = 120 remaining money.
Joanne spends 360 for rent and 240 for groceries and hhold goods.
As we all know,
According to the trigonometric identity,
tan70=tan(20+50)
tan70=(tan20+tan50)/1-tan20tan50
tan70-tan20tan50tan70=tan20+tan50
Also tan70tan20=tan70cot70=1
Hence
tan70-tan50=tan20+tan50
So tan70=tan20+2tan50
Hope this helps :) :)
