There is no ones place after the decimal so 3 is in the tenth place, so 2.4
1. The function of this graph is f(x) = 0.5x + -2
Plug (-2) into the x variables so it looks like:
f(-2) = 0.5 (-2) + -2
Then solve.
Answer: f(-2) = -3
**I'm not as sure about this one, so I might be wrong
2.
For #8, the y-intercept is 4 (you're right) and it represents the initial distance before she started hiking (D)
I tried to figure #9 out, but I couldn't find the answer. I came across a website that might help though: https://sciencing.com/determine-practical-domain-range-10052000.html
**I can't see #s 6 or 7
Answer:
A regular polygon with each interior angle of 170 deg will have each exterior angle as 180–170 = 10 deg. Hence the number of sides in the regular polygon = 360/10 = 36 sides.
Hope this helps

Answer:
A. =4x3+9x2−25x+12
Step-by-step explanation:
(x+4)(4x−3)(x−1)
=((x+4)(4x−3))(x+−1)
=((x+4)(4x−3))(x)+((x+4)(4x−3))(−1)
=4x3+13x2−12x−4x2−13x+12
=4x3+9x2−25x+12
