Answer:
easy
Step-by-step explanation:
So, what we're doing here is solving for x. We must isolate x to find it's value.
Here's how:
17 = 12(x + 2) + 2x
First, we'll distribute the 12
17 = 12*x + 12*2 + 2x
17 = 12x + 24 + 2x
Combine like terms
17 = 14x + 24
Then, we'll subtract 24 from both sides.
17 - 24 = 14x + 24 - 24
-7 = 14x
Then, to isolate x, we'll divide both sides by 14
-7/14 = x
x = -1/2

Answer:
$900
Explanation:
First, we will get the equation representing the graph as follows:
The general form of the linear equation is:
y = mx + c
where:
m is the slope of the line
c is the y-intercept (value of y at x = 0)
From the graph, we can deduce that c = 100
Therefore, the equation now becomes:
y = mx + 100
Now, let's get the slope as follows:
slope = (y2-y1) / (x2-x1)
Using the points (4,300) and (8,500), we can substitute in the equation to get the slope as follows:
slope = (500-300) / (8-4) = 50
Therefore, the equation of the line is:
y = 50x + 100
Finally, we want to get the amount of dollars (y) that will be saved by the 16th month (x).
This means that we will substitute with x = 16 in the above equation and calculate the corresponding value of y as follows:
y = 50x + 100
y = 50(16) + 100
y = $900
Hope this helps :)
