What is x for x^2+2 and y=-3
1 answer:
Hello there! Below this is an attachment of my work for this question and how to solve for it. Allow me to convert my explanation here.
What we are dealing with is called "Composition of Functions", or at least I call it that.
Primarily, we are given the function "g(x)", which just means "G of x".
Whenever we have a problem that states "Find G(#)", we are replacing every single "x" with the number in the given function.
For example;
f(x) = 4x + 2, find f(2)
Replace "x" with 2.
f(2) = 4(2) + 2
f(2) = 8 + 2
f(2) = 10 is your answer.
Hopefully, we now understand our concept of solving this problem.
Take a look into my answer below on paper. Please advise me of any miscalculations or misunderstandings you may find, and I will try my best to elucidate my answer.
I hope this helps!

Dimensions are length 20 meter and width 14 meter
<em><u>Solution:</u></em>
Let "a" be the length of rectangle
Let "b" be the width of rectangle
Given that,
<em><u>A rectangle has width that is 6 meters less than the length</u></em>
Width = length - 6
b = a - 6
The area of the rectangle is 280 square meters
<em><u>The area of the rectangle is given by formula:</u></em>
<em><u>Substituting the values we get,</u></em>
<em><u>Solve the above equation by quadratic formula</u></em>
Since, length cannot be negative, ignore a = -14
<em><u>Thus solution of length is a = 20</u></em>
Therefore,
width = length - 6
width = 20 - 6 = 14
Thus dimensions are length 20 meter and width 14 meter

Answer:
2.5 x miles
Step-by-step explanation:
We are given that 1 light year ≈ 5.9 x miles so:
- 4.3 x 10² light year · <u>5.9 x </u>
<u> miles </u>
- 1 light year
Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:
≈25 x
This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:
≈ 2.5 x miles
