33/7 is 4 5/7 written as an improper fraction.
Answer:
x = 25
Step-by-step explanation:
x + 25 + 2x - 10 + 90 = 180
3x + 105 = 180
3x = 75
x = 25
Answer:y=4
Step-by-step explanation:
2(5y-2)=12+6y
10y-4=12+6y
4y-4=12
4y=16
y=4
The correct answer is: <span>180°
Explanation:
Let's consider each angle one by one:
</span><span>45°: If we rotate the above figure by </span>45°, it will not map onto itself; rather it will make <span>45° angle with the correct figure.
</span>90°: If we rotate the above figure by 90°, it will be perpendicular to the given figure.
180°: If we rotate the above figure by 180°, it will map onto itself exactly.
360°: If we rotate the above figure by 360°, it will map onto itself exactly.
However, as the question is about the least angle, hence, in this case, the correct answer is 180° (since 180° < 360°).
Answer:
Step-by-step explanation:
Let the quadratic function be
The given points must satisfy this function;
Substitute 
.
Substitute (0,-2)
Substitute (1,-4);
Put equation (2) into equation (1)
Put equation (2) into equation (3)
Add equation (4) and (5)
Divide both sides by 3
Put a=3 in equation 5.
The quadratic function is;
