No, I just took the test,
The answer would be
C. P(solid)22
Answer:

Step-by-step explanation:
In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.
In this case we were already given the points for slope:


Slope formula:

Now substitute:

Solve using KCC: (Keep, Change, Change)


=
Because the slope isn't a negative you do not need to simplify the answer.
Hope this helps.
Answer:
3+5=5+3
Step-by-step explanation:
a+b=b+a
comunitive property
Answer:
b = 87°
Step-by-step explanation:
In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>
Using the information we can set up an equation to find the value of b
→ Form equation
63 + 140 + 70 + b = 360
→ Simplify
273 + b = 360
→ Minus 273 from both sides isolate b
b = 87°
