Answer:
Step-by-step explanation:
I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
Answer:
(50+40x) dollars
Step-by-step explanation:
THe fixed cost is $50 (this includes everything and 6GB of data).
Now, for every GB <em>OVER</em> 6 GB he uses, company charges $40 extra.
So, if he used "x" GB EXTRA, his EXTRA cost will be 40 * x = 40x
Thus, his total cost in the month would be fixed cost PLUS the extra, which would be
50 + 40x dollars
Answer: x = 20, y = -15
Step-by-step explanation:
Since we already know that 
, we can just substitute in that value of y into the other equation:
with the value of x, we can find the value of y:

Answer:
305 and 793
Step-by-step explanation:
LCM * HCF = product
3965 * 61 = 241,865 = 5*13*61*61
HCF = 61 so
61*5 = 305
61 * 13 = 793
