puteri [66]3 years ago

We would first determine how to solve this, and then from there, we would then see whether the following answer would be the correct answers.

2x^2 -  50 \\ \\ Pull \ out \ like \ factors : \\ 

   2x^2 - 50  =   2 * (x^2 - 25) \\ \\    Factoring: \\    x^2 - 25 \\ \\ (your \  answer)...\\ \\   2 * (x + 5) * (x - 5)

Now, we can determine whether the say "yes" or "no" to the following answers.

<span>a 2(x-5)(x+5) = YES
b -2(x+5)(x+5) = NO
c -2(5-x)(x+5) = NO</span>

What is 8,414.00065 to the nearest cent
kozerog [31]

Answer:

8414

Step-by-step explanation:

Here, "to the nearest cent" just basically is asking for "to the nearest whole number".

When rounding to the nearest whole number (i.e. without any decimal places), you must look at the tenths digit (the digit right after the decimal point).

If the tenths digit is any number 0 to 4, you round down; in other words, you keep the original whole number. For example, if we want to round 5.2, since the tenths digit is 2, we round down to 5.

If the tenths digit is any number 5 to 9, you round up. For example, if we want to round 5.7, since the tenths digit is 7, we round up to 6.

In this case, the tenths digit is 0, so we round down to 8,414.

Hope this helps! Please mark me brainliest if possible! :)

Please help if you understand this <br> Which is the graph of the identity function
konstantin123 [22]

Answer:

Please check the explanation.

Step-by-step explanation:

The function f(x)=x is called the identity function.

In other words, x GOES IN, X COMES OUT.

From all the graphs, the 3rd graph represents the identity function as the input and output of this graph remains the same.

The 3rd graph indicates that:

  • at x = 1, y = 1
  • at x = 2, y = 2
  • at x = -1, y = -1
  • at x = -2, y = -2

So, it is clear that input and output of this 3rd graph remains the same.

The solution graph is also attached below.
