Answer:
x = 35 degrees
Step-by-step explanation:
∠BCA = ∠DAF because they are corresponding angles.
∠BCA + 42 + 103 = 180 (angles in a triangle = 180)
∠BCA = 180 - (42+103)
∠BCA = 35
∠BCA = x (corresponding angles)
x = 35
Answer:
B. 
Step-by-step explanation:
We have been given a system of equations. We are asked to choose the ordered par that is the solution to the given system.
To solve our given system, we will equate both equations as:
Combine like terms:
Upon substituting 
in equation (1), we will get:
Therefore, the ordered pair is the solution of the given system and option B is the correct choice.
Answer:
B. (6,-2)
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
The center of the circle is (h,k)
So, in this problem, h is 6 and k is -2, so the center of this circle is (6,-2).
Answer:
The written form would be "Nine more than three times a number is greater than -18.
Step-by-step explanation:
To graph it, you must first solve for x.
3x + 9 > -18
3x > -27
x > -9
Now we can graph this by putting an open dot at -9 and then drawing an arrow to the right.
Answer:
2 over 5
Step-by-step explanation:
What you need to do is find a common denominator. In this case it is 15. 2 over 5 = 6 over 15 so since 6/15 < 7/15 and 6/15= 2/5, 2/5 < 7/15
