Answer:
A) 30°
Step-by-step explanation:
Sum of three angles of a triangle = 180°
75° +75° + ∠WYZ = 180°
Add like terms
150° + ∠WYZ = 180°
Subtract 150°from both sides
∠WYZ = 180 - 150
∠WYZ = 30°
It's a linear function.
Domain of a linear function is the set of all real numbers.
If the slope of linear function is different than 0, then range is the set of all real numbers.
We have f(s) = 7s + 15. The slope = 7 ≠ 0. Therefore:
Answer:
Answer:
One of these
Step-by-step explanation:
Answer:
The correct answer is the first option, the center of the circle is at (-2,4) and its radius is 15.
Step-by-step explanation:
A circle can be represented by the following equation:
Where are the coordinates of the center of the circle and is its radius. Comparing this to the given expression we can determine that the center of the given circle is and the radius is , therefore the correct answer is the first option.
