We plug in a as the value of x in the equation, and we get 12 + 2y = 12, which simplifies to 2y = 0 and we get y or b = 0.

The weight of a rock sample is measured to be 2.5 pounds. What is the percent of error in the measurement? 2% 5% 10%
elixir [45]

Answer:

The percent of error in the measurement is 2%

Step-by-step explanation:

The percent of error associated with a reported measurement is calculate using the formula;

percenterror=\frac{error}{measurement}*100

The error associated with a measurement is defined as half of the smallest unit of measurement used. The measurement reported was 2.5. The smallest unit of measurement for this reading is 0.1. The error is thus;

error = 0.1/2 = 0.05

The percent of error is thus;

\frac{0.05}{2.5}*100=2

I need help remembering the steps to solve a polynomial equation
murzikaleks [220]
Example 1 – Solve: 3x3 = 12x

Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

 3x^3-12=0

Step 2: Use a factoring strategies to factor the problem.

 3x(x^2-4)=0
3x(x+2)(x-2)=0

Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.

 3x=0 or x+2=0 or x-2=0

Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.

 x=0 or x=-2 or x=
