Answer:
Our expressions is f(x) = 3|x-7|-7
- in positive values |x-7| is x-7 ⇒f(x) = 3x-28
- in negative ones |x-7| is 7-x wich is the opposite⇒f(x) = 14-3x
Let's calculate the limits in +∞ and -∞
So the right staement is B
Answer:
$12
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Because alternate interior angles are congruent in parallel lines, the angle next to the 25° in the right triangle is 85 - 25 = 60° which makes the other angle in the right triangle 180 - 90 - 60 = 30°. Since they form a straight angle, we can write x + 30 + 85 = 180 → x + 115 = 180 → x = 65°.
6.5*6.5=42.25
1.5*1.5=2.25
(6.5)^2-(1.5)^2=42.25-2.25=40
