Answer:
First and last
Step-by-step explanation:
The first one is a parabola wich is function graph
The last one is straight line
the second isn't a function since some numbers give many values
the thirs is a cercle
Answer:
x^8-x^6+x^3-5
Step-by-step explanation:
The top exponent goes before
Answer:
B. One solution.
Step-by-step explanation:
The solution is the point where the lines intersect.
or we can round it, to say c = 2.19, so hmm that's the missing side
now, we use Heron's Formula, which uses all 3 sides only
and that'd be the area of it
Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
