Answer:
Step-by-step explanation:
12x+2y=36
2y=36-12x
5x+36-12x=22
7x=14
x=2
2y=36-12(2)
2y=12
y=6
btw,next time, please do not include words like(failing ,exam,test,etc) in your question,otherwise, the question might be deleted.
First one is 0.7
Second is 2.5
Third is 3.3
Fourth is 1.6
For the second question I got $2.34
Answer:
Horizontal asymptote of the graph of the function f(x) = (8x^3+2)/(2x^3+x) is at y=4
Step-by-step explanation:
I attached the graph of the function.
Graphically, it can be seen that the horizontal asymptote of the graph of the function is at y=4. There is also a <em>vertical </em>asymptote at x=0
When denominator's degree (3) is the same as the nominator's degree (3) then the horizontal asymptote is at (numerator's leading coefficient (8) divided by denominator's lading coefficient (2)) 
Answer:
the answer to the question is 8x⁴- 5x²y² - 6y⁴
Step-by-step explanation:
the normal way of using BODMAS is apply to all polynomial equations.
subtracting -6x⁴- 3x²y² + 5y⁴ from 2x⁴ - 8x²y² - y⁴.
polynomial of the same degree is very easy to calculate. this equation is having the same degree of polynomial all through, therefore:
Applying Bracket to the equation
2x⁴ - 8x²y² - y⁴- ( -6x⁴- 3x²y² + 5y⁴)
Open the bracket
2x⁴ - 8x²y² - y⁴ +6x⁴+3x²y² - 5y⁴
collects the likes terms
2x⁴ +6x⁴- 8x²y² +3x²y² - 5y⁴ - y⁴
The final answer is =
8x⁴- 5x²y² - 6y⁴
