Answer:
y=-1/2 x-4
Step-by-step explanation:
y=mx+c
c is -4
m is rise/run so -1/2
Answer:
Not a polynomial
Step-by-step explanation:
A polynomial is a combination of terms separated by
+
or
−
signs. A polynomial does not contain variables raised to negative or fractional exponents, variables in the denominator or under a radical, or any special features such as trigonometric functions, or logarithms.
Mode means MOST. Which number is displayed the most?
39, 43, 43, 50, 55, 61, 75, <u>78, 78, 78</u>
Answer: 78
Note: I placed the data set into numerical order because it will help you to easily find the mode and also the median (middle number).
Answer:
Identity is verified.
Step-by-step explanation:
We have to verify the identity 
To prove any identity we always prove one side(either left hand side or right hand side) of the equation equal to the other side.
In this identity we take the left hand side first

(as we know cos(a+b) = cosa×cosb-sina×sinb)


= - sinx ( Right hand side)
Hence identity is proved.
