Answer:
3
Step-by-step explanation:
The linear function
One of the points is (0,5), so
f(0) = 5
The y-intercept is at (0,5).
===============
The exponential function
The general formula for an exponential function is 
.
=====
Calculate the <em>value of b
</em>
y₃/y₂ = [a(b)³]/[a(b)²]
250/50 = b
b = 5
=====
Calculate the <em>value of a
</em>
250 = a(5)³
250 = a × 125
a = 2
=====
g(0) = 2(5)⁰
g(0) = 2 × 1
g(0) = 2
=====
|f(0) – g(0)| = |5 – 2|
|f(0) – g(0)| = 3
The positive difference in the y-intercepts of f(x) and g(x) is 3.
You can see the two y-intercepts on the graph below.
Answer:
A. round
Step-by-step explanation:
simple answer, I think you were just joking
<span>This answer assumes that the majority of the 1,500 miles are on the highway. After adding up the total cost for the trip for each car, the Toyota Camry is the better value.
Toyota Camry:
Base Price: $553.28
Gas Price: $172.72
Total Price: $726.01
Toyota Prius:
Base Price: $804.61
Gas Price: $118,75
Total Price: $923.36
Therefore, based on the distance traveled on this trip, the Toyota Camry is the better value. A longer trip would likely turn the Prius into the better value but not for a 1,500 mile trip.</span>
Answer:
The answer would be B
2.5x = 45
(x) would be the number of dolls, multiplied by how much each doll costs ($2.50) and the product would be how much she has to spend. Hope this helps!
Answer:
1, 3, 4, and 10
Step-by-step explanation:
To get a y value, substitute the x value into the equation they gave you (y = 3x - 5). For the x value 2:
y = 3(2) - 5
y = 6 - 5
y = 1.
To get a missing x value, solve for x in the equation they gave you. You were given the y value, so you can substitute that into the equation.
(4) = 3x - 5
Add 5 to both sides
9 = 3x
Divide both sides by 3
3 = x
Do the same with 7
(7) = 3x - 5
Add 5
12 = 3x
Divide by 3
4 = x
For the last one, you're given x so substitute it into the equation:
y = 3(5) - 5
y = 15 - 5
y = 10
