Answer:
n = 1, 4
Step-by-step explanation:
Step 1: Write equation
n² - 5n + 4 = 0
Step 2: Solve for <em>n</em>
<u>Factor:</u> (n - 4)(n - 1) = 0
<u>Find roots:</u> n = 1, 4
Step 3: Check
<em>Plug in n to verify if it's a solution.</em>
1² - 5(1) + 4 = 0
1 - 5 + 4 = 0
-4 + 4 = 0
0 = 0
4² - 5(4) + 4 = 0
16 - 20 + 4 = 0
-4 + 4 = 0
0 = 0
Step-by-step explanation:
Use PEMDAS

The domain is all x-values of coordinate pairs.
But, if you need a reasonable domain for a graph, it should be all integers (whole numbers) greater than or equal to zero.
This is because you can’t have 1/2 of a person or 1/2 of an engine. You also can’t have any negative engines either. Therefore, the domain would need to be whole numbers greater than (or equal to 0).
Answer:
125
Step-by-step explanation:
50 x 150% = 75
75 + 50 = 125
This answer can easily be plugged into a calculator. =)
3 + 1234 = 1237
