Step-by-step explanation:
x less than or equals to -8
Answer: b.) 40
Given that:
f(x) = 5 × 2ˣ
To find f(3), simplify insert [x = 3] in the given equation:
f(3) = 5 × 2³
f(3) = 5 × 2 × 2 × 2
f(3) = 40
Answer:
0.200
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-4-(-4*x-2)=0
Step by step solution :
STEP 1
1.1 Pull out like factors :
10x - 2 = 2 • (5x - 1)
STEP 2
2.1 Solve : 2 = 0
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : 5x-1 = 0
Add 1 to both sides of the equation :
5x = 1
Divide both sides of the equation by 5:
x = 1/5 = 0.200
solution:
x = 1/5 = 0.200

Answer:
659
Step-by-step explanation:
We assume the daily rate increases at each multiple of $50. When the balance reaches $50 on day 25, the pay on day 26 is $2.25.
Similarly, when the balance reaches 9628.75 on day 658, the pay will be $50 on day 659.

I found this easiest to solve using a computer program. A spreadsheet can do it by computing the number of days between raises. This is shown in the attachment.
