Answer:
u = 8
Step-by-step explanation:
3u + 5u = 64
8u = 64
8u/8 = 64/8
u = 8
Answer: <em>u = 6</em>
Step-by-step explanation: To solve for <em>u</em> in the equation you see here, we must first isolate the term containing <em>u</em> which in this problem is -6u.
Since 7 is being added to -6u, we subtract 7 from both sides of the equation to isolate the -6u. On the left side of the equation, the +7 and -7 cancel out and on the right side of the equation, -29 - 7 is -36 so we have -6u = -36.
Now we can finish things off by just dividing both sides of the equation by -6. On the left the -6's cancel and on the right -36 divided by -6 is 6.
So u = 6 and you can check your answer by 6 back in for <em>u</em> in the original equation shown below in italics.
<em>-6 (6) + 7 = -29</em>
The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
The line passes through the point (1, 8) and (2, 16), hence:

The equation of the line is given by y =8x
