Use the intersect method to solve the equation. x2-3=x2-1

Mathematics
1 answer:
Ivahew [28]2 years ago

The values of x are 1 and - 1

<h3>What is the intersect method?</h3>

The intersect method would use the graphs of both equations to find points where they would cross each other. In this instance, the graphs would cross each other at two points

Let's solve the equation:

Rearrange all nonzero terms to the left side of the equation:

x² - 3 + x² - 1 = 0

Combine like terms:

2x² - 2 = 0

Reduce the greatest common factor on both sides of the equation:

x² - 1 = 0

Factor the expression using :

a² - b² = ( a + b) ( a- b) : ( x - 1) ( x + 1) =0

Apply Zero Product Property:

x + 1 = 0 or x -1 = 0

Rearrange unknown terms to the left side of the equation:

x = - 1

Rearrange unknown terms to the left side of the equation:

x = 1

Thus, the values of x are 1 and - 1

For a sample of n = 30 scores, X = 45 corresponds to z = 1.50 and X = 40 corresponds to z = +1.00. What are the values for the s
Ber [7]

Answer:

Sample mean = 30

Standard deviation = 10

Step-by-step explanation:

A system with two linear equations can be modeled with the information given in order to find the sample mean (M) and the standard deviation (s):

z=\frac{X-M}{s}\\\\1.50=\frac{45-M}{s} \\1.00=\frac{40-M}{s}

Solving the linear system:

40-M = \frac{45-M}{1.5}\\M=\frac{15}{0.5}\\M=30\\\\s=\frac{45-30}{1.5}\\s=10

The sample mean is 30 while the standard deviation is 10.
