Answer:
Step-by-step explanation:
To write an equation, use the slope-intercept equation:
M is the slope and b is the y-intercept.
First, find the slope by using the slope formula for when you have two points:
Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:
Simplify parentheses (two negatives make a positive) and simplify:
The slope, m, is 4. Insert this information into the equation:
Now, take one of the points and insert into the slope-intercept formula:
Solve for b, the y-intercept. Simplify multiplication:
Add 20 to both sides and simplify:
The y-intercept, b, is 20. Insert this value into the equation:
Done.
It would be 1832 fahrenheit.
Answer:
Wait time=6hrs25min-3hrs55 min

Since 1 and 2 are used at least once in half of the apartments, and no other number is used this often, either 1 or 2 will be the most frequent digit used.
<span>Since all of the numbers of the form </span><span> appear but only 6 of the numbers </span><span> appear, 2 will be used less often than 1 and we should count the number of 1s to find the number of packages needed.</span>
100 through 125 requires 26 ones just for the hundreds place. 100 through 125 and 200 through 225 require the same number of ones for the tens and units places; that is, thirteen.
<span>So, there are </span><span> ones used. Therefore, the landlord must purchase </span><span> 52 packages.</span>
