Answer:
3 miles
Step-by-step explanation:
5% of one inch = 0.05 inches
0.5/30 = 0.05/x
0.5x = 1.5
x = 3
Notice how you can also simply divide 30 by 10 in this case? :)
Answer:

Step-by-step explanation:
To write an equation into slope-intercept form, or y = mx + b format, we need to find the y-intercept of the line and its slope and substitute values for m and b.
1) First, find the y-intercept. The y-intercept is the point at which the line intersects the y-axis. Reading the graph, we can see that the line passes the y-axis at the point (0,2), thus that is the y-intercept.
2) Next, find the slope. Pick out two points on the graph to use for the slope formula,
. I chose to work with (0,2) and (6,1). Now, substitute the two points' x and y values into the formula appropriately and solve:

Thus,
is the slope.
3) Now, substitute the calculated values into the y = mx + b format. The b represents y-value of the y-intercept. The y-intercept is (0,2), thus substitute 2 for b. The coefficient of the x term, or m, represents the slope, thus substitute
for m. This will give the following equation of the line in slope-intercept format:

To solve an exponential equation, take the log of both sides, and solve for the variable. Example 1: Solve for x in the equation . Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80).. Check: Check your answer in the original equation.
