The condition for an expression to be an <u>identity </u>is that both sides of equality must give the same value.
In this case, the equation that fulfills that condition is the first equation (1).
<u>Let’s prove it:</u>
1)
Applying distributive property:
Joining together similar terms on both sides of the equality:
<h2>
>>>>>>>This is true and fulfills the condition of identity</h2>
The other equations do not fulfill the condition:
2)
>>>>>>>This is not logic
3)
>>>>>>>This is not logic
4)
>>>>>>>This is not logic
A quadratic a function has a form of,
The first function has a term which doesn't fit the profile of a quadratic function. The highest exponent on x inside a quadratic function can be 2, but here we have 3 so this is not a quadratic function, but rather a cubic function.
The second function fits the form of a quadratic function perfectly.
The third function is a bit tricky. While technically the third function could be considered quadratic if the leading term would be something like and we did't even see it written out because multiplying with 0. But when we specified the form of a quadratic function, we strictly said that the number before aka cannot equal to zero. So the last function is not a quadratic function but rather a linear function.
Hope this helps :)
Answer:
53
Step-by-step explanation:
5+3=8, 53 flipped is 35, and 53-35=18
An integer is a whole number.
-17/n
Replace n with the choices:
-17/18 = -0.9444
-17/102 = -0.1666
-17/170 = -0.1
None of those are a whole number so the answer would be d. None of them.
