You would take 280-105=175 miles away and take 105 and divide that by your time 1.5 too get 70 mph
When you do (f+g)(x), all you have to do is take both functions and add them to each other. It should look like this when you set it up:

Then just add like terms and you should get:

Hope this helped.
The angle (2y - 5)° and 95° are vertical angles, then they are congruent, that is,

Solving for y:

The angle (3x + 55)° and 85° are vertical angles, then they are congruent, that is,

Solving for x:

Finally, the value of x + y is:

A.) The completed table is in the attached picture.
Per capita calculation steps Step 1: Per capita = MV Deaths / Population
Step 2: Convert to Scientific notation
Step 3: Round-off to hundredths (2nd digit from the right of decimal place)
Per 100K people calculation steps Step 1: Per 100K people = MV Deaths / Population * 100, 000
Step 2: Round-off to tenths (1st digit from the right of decimal place)
B) I used my completed table (attached picture)
Therefore,
Indiana has the worst rate with 11.6 MV Deaths per 100K People
C) Again, I used my completed table (attached picture)
Therefore,
Illinois has the best rate with 7.3 MV Deaths per 100K People
To find the zeros set the equation equal to zero:
x^2 - 5x +4 = 0
Factor:
(x-4) (x-1) = 0
Now solve each set of parenthesis so that they equal zero:
(x-4) = 0, x =4
(x-1) = 0, x = 1
The zeros are 1,4
