The answer is b because are congruent
A vertex can be the max or min. The vertex is the highest point or lowest point of a function.
Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
The number in question is equal to 2 times the temperature in degrees Celsius.
<h3><u>Equations</u></h3>
Since Alisha is working on a project about temperature conversion in her science class, and the formula for converting degrees Celsius to degrees Fahrenheit is F=C+32, to solve FC + 32 the following equation must be performed:
- CF + 32 = X
- F + F + 32 + 32 = X
- 2F + 64 = X
- F + 32 = 1/2X
- X = 2C
Therefore, the number in question is equal to 2 times the temperature in degrees Celsius.
