An exponential growth function
A logarithmic growth function
An exponential decay function
A logarithmic decay function

Answers

Answer:

Exponential decay.  Your growth factor is 1/8, which is between 0 and 1.  Thus, the value is decreasing exponentially.

If the growth factor is greater than 1, you have exponential growth.  Logarithmic functions will always contain a logarithm, so you can quickly rule out those options.

Kimi brought chocolate and vanilla cupcakes to school for her birthday. 2 students picked a vanilla cupcake and 18 students picked a chocolate cupcake. What percentage of the students picked a vanilla cupcake?

Answers

10% is your answer. Take the total number of students and use that as a divisor of 100 so 100/20 = 5% so each kid represents 5 percent. Then if you take the 2 kids who got vanilla cup cakes and if each one is 5% then 5%+5%= 10%

Answer: 10% of students picked a vanilla cupcake.

Explanation: 18 + 2 = 20. 20 is 100% of 20. 20/10 = 2, and 2 is 10% of 20, therefore 10% of students picked a vanilla cupcake.

55x + 10 = 230
What is x?

Answers

Answer:

x = 4

Step-by-step explanation:

55x + 10 = 230

=> 55x = 230 - 10

=> 55x = 220

=> x = 4

Therefore, x = 4.

Hoped this helped.

Answer:

x= 4

Step-by-step explanation:

solving equation step-by-step.

55x + 10 = 230

Subtract 10 from both sides.

55x + 10 − 10 = 230 − 10

55x = 220

Divide both sides by 55.

55x/55 = 220/55

x= 4

Our Answer: x= 4

3. Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solution. Show why this is true by solving the system of equations given. Justify the reason for each step. HINT: Use the addition property of equality and multiplication property of equality in your answers. (8 points: 1 point for each question)

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

Why is this multiplication allowed? (1 point)

What variable will be eliminated when the equations are combined after

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

Why can you add the equations? (1 point)

Substitute x back into one of the equations to solve for y. (1 point)

What is the solution to the system of equations? (1 point)

Answers

Answer:

Step-by-step explanation:

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

5x + 2y = 7

6x –2y = 4

Why is this multiplication allowed? (1 point)

Because the entire equation was multiplied by the same number, the equation remains the same.

What variable will be eliminated when the equations are combined after  the multiplication? (1 point)

The Y variable

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

11x = 11

Solve the equation for x. (1 point)

X = 1

What is the solution to the system of equations? (1 point)

X = 1 and Y = 1 so the answer is (1, 1)

(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)
