Answer:
<M = <S
Step-by-step explanation:
If ΔMNO ≅ Δ SQR then
<M = <S
You flip the inequality.
Example: if x > -y and you divide both sides by (-1) then you flip the inequality so: -x < y
One pizza serves four people so, you will need 10 pizzas for 40 people so that make the answer (A.)
Answer:

Step-by-step explanation:
Since the equation is parallel, this means that the slope remains the same which is 0.5.
The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.

When solving for b, it will equal to -5.
Therefore the new equation that is parallel is 
Answer:
B
Step-by-step explanation:
A 90 degree rotation would be a rotation of 90° about the origin. Knowing this, we can eliminate C since it is a 180° rotation. We can also eliminate A, as it would be a 0° or 360° rotation. This leaves us with B and C.
A counterclockwise rotation would be one that goes the opposite direction of the rotation of the hands of a clock. A 90° counterclockwise rotation would yield triangle B, making that our answer.
I hope you find my answer and explanation to be helpful. Happy studying.
