Whats this method called? How do you use this strategy for other questions?
Ivan

Answer with Step-by-step explanation:

The method uses the formula of the right angles triangle, more precisely the pythogorean formula,

In step 2, it is the power law of indices,

Other than this, other tricks used here is the using of square root on step no 6.

You can take the square root ,cube root, square, etc in equations but you have to do it on both sides, you can even add r subtract numbers and do all sorts of things.

it is the process of solving equations by equality.

Eg:

x=5

x^2=5^2

√x=√x

x-7=5-7

8/2x=8/2*5, etc

Can someone help me pls
Sati [7]

Answer: No solution

Step-by-step explanation:

First, rearrange the second function:

3x - y = 2 \\-y=-3x+2\\y=3x-2

Because the two equations share the same slope of 3, they're parallel lines, that means they don't ever intercept. Therefore, there are no solutions.

Which of the -values are solutions to the following inequality?
Andrej [43]

We have been given an inequality 38. We are asked to choose the solutions of our inequality from given choices.

The solution of inequality are all values of x greater than 38.

Let us see our given choices one by one.

A. x=25

Since solution of inequality is greater than 38 and 25 is less than 38 , therefore, 25 is not a correct choice.

B. x=40

Since the solution of inequality is greater than 38 and 40 is greater than 38, therefore, 40 is the correct choice.

C. x=120

Since the solution of inequality is greater than 38 and 120 is greater than 38, therefore, 120 is the correct choice.

Hence x=40 and x=120 are solution for the given inequality.

Determine if the function is one-to-one.<br><br>​
olya-2409 [2.1K]

Answer:

No

Step-by-step explanation:

From what I saw on google for what "one to one" means, It's basically meaning that the bottom of that quadratic function is at point (0 , 0) and hits both (-1 , 1) and (1 , 1) on the graph.
