Consider the slopes and y-intercepts of each system of equations.
Choose True or False for each statement.
a. y=x + 6 and y = -x + 5 has only one solution.
b. y- 5 = 4x and y = 4x - 5 has no solution.
c. 2(3x + 4) = y and y = 6x + 5 has only one solution.
d. 9 + y = 6x and 6x - y = 9 has an infinite number
of solutions

cause it equals more

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
