Answer:
see below
Step-by-step explanation:
In a proportional relationship, the ratio of y to x is the same for all values of x and y. Here, you can determine if that is the case by looking at the first two table entries in each table.
A. -4/1 = -12/3 . . . proportional
B. -5/1 ≠ -13/3 . . . not proportional
C. -4/1 ≠ -16/3 . . . not proportional
D. -8/1 ≠ -20/3 . . . not proportional
Answer:
63x + 18
Step-by-step explanation:
9 multiply 7x to give 63x
and 9 multiplies 2 to give 18
Answers:
Angle A = 104 degrees
Angle B = 76 degrees
=================================
Supplementary angles add to 180 degrees.
A+B = 180
(3x-7)+(2x+2) = 180
5x-5 = 180
5x-5+5 = 180+5 ... add 5 to both sides
5x = 185
5x/5 = 185/5 .... divide both sides by 5
x = 37
Use x =37 to find
Angle A = 3x-7 = 3*37-7 = 111-7 = 104 degrees
Angle B = 2x+2 = 2*37+2 = 74+2 = 76 degrees
As a check: A+B = 104+76 = 180 so that helps confirm the answer
