Right now, we are all as confussed as you are.
Let's call f(x) = 2x - 4 and g(x) = 3⁻ˣ + 1.
<span>First, you need to evaluate each function at the given values of x.</span>
f(1) = 2(1) - 4 = -2
f(3.25) = 2(3.25) - 4 = 2.50
f(2.5) = 2(2.5) - 4 = 1
f(2) = 2(2) - 4 = 0
Similarly:
g(1) = <span>3⁻¹ + 1 = 1.33
g(3.25) = </span><span>3⁻³'²⁵ + 1 = 1.03
g(2.5) = </span>3⁻²'⁵ + 1 = 1.06
g(2) = 3⁻² + 1 = 1.11
Now, look for the value of x for which f(x) ≈ g(x): this happens for x = 2.5
Therefore the correct answer is c) x ≈ 2.5

Answer:
(2,2)
Step-by-step explanation:
Given equations are
x+3y=8 eq(1)
2x-y=2 eq(2)
we'll solve the system of equation by substitution.
Adding -3y to both sides of eq(1),we get
x+3y-3y=8-3y
x+0=8-3y
x=8-3y eq(3)
Put above value of x in eq(2),we get
2(8-3y)-y=2
16-6y-y=2
16-7y=2
Adding -16 to both sides of above equation,we get
-16+16-7y=-16+2
0-7y=-14
-7y=-14
Dividing by -7 to both sides of above equation,we get
-7y/-7=-14/-7
y=2
Putting y=2 in eq(3),we get
x=8-3(2)
x=8-6
x=2
hence, the solution for this system of equations is (2,2).
Since there is no number for the number of pounds for the polar bear, you would use p to represent polar bears. The expression would be: 1578 - p. Good luck
