3y+15> -6

a. y> 3
b.> -7
c. y> 13
d. y> -17

B)  y  >  − 7  

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Inequality Form: y > − 7      Interval Notation: ( − 7 , ∞ )

mental cunning

explanation:

he is often referred to as a man of twists and turns

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
