Answer:
option A
Step-by-step explanation:
f(x)+g(x) will lead to addition of the fractions
LCM of 2x and x² is 2x²
{(2x²×½x)+(2x²×4/x²)}/2x²
x+8/2x²
Answer:
A
Step-by-step explanation:
Consider Δ JKL and Δ GDF
If the ratios of corresponding sides are equal then the triangles are similar.
= =
= =
= =
Since the ratios are equal then Δ JKL and Δ GDF are similar by SSS postulate.
C) When (2, 3) is substituted into the second equation, the equation is false
D) When (2, 3) is substituted into the first equation, the equation is true.
Step-by-step explanation:
Rewrite it into vertex form with completing the square:
f(x) = x^2 - x + 2 = (x^2 - x) + 2 = (x^2 - x + 1/4) + 2 + 1/4 = (x - 1/2)^2 + 9/4;
So the vertex is (1/2, 9/4).
