Answer:
, explanation for how to get there
Step-by-step explanation:
If we have the equation , we want to isolate c on one side and find it's value.
Let's first divide both sides by 4.
Now let's solve for the absolute value. We know that:
or
Possibility 1:
Subtract 3c from both sides:
Possibility 2:
Add 4c to both sides:
Subtract 5 from both sides:
Divide both sides by 7:
Plugging both of these values into the equation, we can see that only 5 works.
Hope this helped!
Answer:
No, the absolute value of a number is different from the opposite.
Step-by-step explanation:
For example, the absolute value of 4 is 4.
l4l = 4
But the opposite of 4 is -4.
Absolute value is ALWAYS positive, but the opposite of a positive number is a negative number.

Answer:
<u>option A. f(x) = -x² + 8x − 14</u>
Step-by-step explanation:
The standard form of a quadratic equation in general is as following:
f(x) = ax² + bx + c.
Where a, b and c are constants and a ≠ 0.
So, for the given function:
f(x) = -(x − 4)² + 2
∴ f(x) = - (x-4) (x-4) + 2
∴ f(x) = - [ x(x-4) - 4(x-4) ] + 2
∴ f(x) = - ( x² - 4x -4x + 16 ) + 2
∴ f(x) = - ( x² - 8x + 16 ) + 2
∴ f(x) = -x² + 8x - 16 + 2
∴ f(x) = -x² + 8x - 14
So, the answer is option<u> A. f(x) = -x² + 8x − 14</u>
