Answer:
The second step because she distributed within the parentheses without adding the negative sign to 13
Answer:
The answer is ( 1 , -2) in point form or x = 1 , y = -2 in eqaution form.
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
The Answer is C.
Step-by-step explanation:
f(x) = cos x , g(x) = cos(x - π/4)
Equation: f(x) = a * cos (x - h) + k
Since the equation only has h = π/4, it means that it shift right.
The equation that can not be represented is B because the variables are mixed up and are not matching with the correct formula.
