Consider : y² = 25
⇒ y = ![\sqrt{25}](https://tex.z-dn.net/?f=%5Csqrt%7B25%7D)
We know that : 5² = 25 and also (-5)² = 25
⇒ y = ![\sf{\sqrt{(5)^2} \ \text(or) \ \sqrt{(-5)^2}}](https://tex.z-dn.net/?f=%5Csf%7B%5Csqrt%7B%285%29%5E2%7D%20%5C%20%5Ctext%28or%29%20%5C%20%5Csqrt%7B%28-5%29%5E2%7D%7D)
⇒ y = +5 or -5
So, The Answer is C

Step-by-step explanation:
The equation of elevation for the dolphin is:
![-\frac{67}{4} + 5\cdot x = -\frac{21}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B67%7D%7B4%7D%20%2B%205%5Ccdot%20x%20%3D%20-%5Cfrac%7B21%7D%7B4%7D)
![5\cdot x = \frac{56}{4}](https://tex.z-dn.net/?f=5%5Ccdot%20x%20%3D%20%5Cfrac%7B56%7D%7B4%7D)
![x = 2\,\frac{4}{5}\,ft](https://tex.z-dn.net/?f=x%20%3D%202%5C%2C%5Cfrac%7B4%7D%7B5%7D%5C%2Cft)
Answer:
Step-by-step explanation:
9 rings because 5+4=9
The answer is letter C and E.
For A and B, they look like a linear transformation, however
when you add the constants, it will not zero out. For letter D, it is not a linear
transformation because of the scalar multiplication. The value given in D is an
absolute value, so whether or not you multiply this, it will not result to the
same number.
