Answer:
c is correct answer is yes
While a digit in the thousands place has a value 1,000 times the value of the digit. So to compare you can do 10,000 / 1,000 = 10, which means that a digit in the ten thousand place values ten times what the same digit values is it is the thousand place.
Assuming the missing parenthesis is at the end the simplified answer should be k-8
The answer is 70.
5 + 2 = 7
7 x 10 = 70
Y = -5x + 28
will be parallel to your equation because it has the same coefficient but will also pass through (3, 13)
