The 8 is a, the 3 is b and -45 is c
Plug them into the quadratic formula
Answer:
7
Step-by-step explanation:
Ordered pair for 6x-4y=16
Answer:
k=16
Step-by-step explanation:
Combine all the like terms
- 2k+10+5k-25+3k+35 =180
- (2k+5k+3k) + (10-25+35) = 180
- 10k + 20 = 180
Solve for k by subtracting 20 on both sides and then dividing by 10 on both sides
For this case we have that by definition, a linear function is of the form
