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:
total price inluding tax is $43.20
Step-by-step explanation:
pants cost: $40
Tax amount: 8% of $40 -> 40 x 0.08 = $3.20
pants + tax:
$40 + $3.20 = $43.20
Answer:
∠ 2 = 140°
Step-by-step explanation:
the left base angle in the triangle and 110° are a linear pair and sum to 180°
base angle + 110° = 180° ( subtract 110° from both sides )
base angle = 70°
the 2 sides of the triangle are congruent so Δ is isosceles with base angles congruent.
the vertex of the Δ is then
(180 - 70 - 70)° = 180° - 140° = 40°
the vertex and ∠ 2 are a linear pair and sum to 180° , that is
∠ 2 + 40° = 180° ( subtract 40° from both sides )
∠ 2 = 140°
Answer:
The right answer is A.
As a result of it being raised to a negative number, you write its inverse.
