Answer:
Proved See below
Step-by-step explanation:
Man this one is a world of its own :D Just a quick question are you a fellow Add Math student in O levels i remember this question from back in the day :D Anyhow Lets get started
For this question we need to know the following identities:

Lets solve the bottom most part first:

Take LCM

now break the LCM

because 1/tan = cot x
and furthermore,

now we solve the above part and replace the bottom most part that we solved with 

Hence proved! :D
Answer:
22x+10y
Step-by-step explanation:
15x + 2y + 7x + 8y ----> 22x+10y
Answer:
You can find and write the equations in Slope-Intercept form due to the slope and y-intercept.
Step-by-step explanation:
The Slope-Intercept Form Formula: y=mx+b
The m represents the slope while the b represents the y-intercept
You can also use y2 - y1 / x2 - x1 to find the slope which is the m in your formula.
Lastly, to find a y-intercept, you can plug in your coordinate for the x and y to do two-step linear equations.
Cause 5+3+8, 8+3=11 11+3=14, so 14+3=17 17+3=20, 20+3=23 23+3=26 26+3=29 29+3=32
so its 5, 8, 11, 14, 17, 20, 23, 26, 29, 32
so the answer is 32
