Answer:
the value of x that makes this equation true is 9
Step-by-step explanation:
2(x - 6) + x + 14 = 4(x - 3) + 5
<em>open the parenthesis</em>
2x - 12 + x + 14 = 4x - 12 + 5
<em>add 12 to both sides of the equation</em>
2x - 12 + 12 + x + 14 = 4x - 12 + 12 + 5
2x + x + 14 = 4x + 5
<em>subtract 5 from both sides of the equation</em>
2x + x + 14 - 5 = 4x + 5 - 5
3x + 14 - 5 = 4x
3x + 9 = 4x
<em>subtract 3x from both sides of the equation</em>
3x - 3x + 9 = 4x - 3x
9 = 4x - 3x
9 = x
check the answer:
2(x - 6) + x + 14 = 4(x - 3) + 5
2(9 - 6) + 9 + 14 = 4(9 - 3) + 5
29 = 29
Answer:
(1, -3/2)
Step-by-step explanation:
Given:
The table shown the number of campers, x, at a local campsite and the total amount of money, y, in dollars, earned by the camp site.
To find:
The unit for the rate of change.
Solution:
We know that, rate of change is the change in y-values with respect to x-values, i.e.,
In the given problem, y is the total earnings in dollars and x is the number of campers. So, the rate of change represents the change is earnings with respect to number of campers.
Thus, the unit of rate of change is dollars per camper.
Therefore, the correct option is D.
