Let x = Tom’s allowance
Let x/2 = the amount he spent going to the movies.
So x – x/2 = the amount he has left after she went to the movies
he washed the car and earned nine dollars, so you’d add that amount in
x – x/2 + 9
the amount he has left over is 13 dollars
x – x/2 + 9 = 13
Now you solve for x
x – x/2 + 9 = 13
x/2 + 9 = 13
x/2 = 4
x = 8
His allowance is $8
To check your work, plug 8 into the equation:
8 – 8/2 + 9 = 13
8 – 4 + 9 = 13
<span>13 = 13</span>
We will use the Reminder theorem.
The polynomial f ( x ) is divisible by x - a when f ( a ) = 0.
For the 1st one:
f ( - 2 ) = ( - 2 )³ + 7 · ( - 2 )² + 14 · ( - 2 ) + 8 =
= - 8 + 28 - 28 + 8 = 0
For the 2nd one:
f ( 5 ) = 3 · 5³ - 12 · 5² - 4 · 5 - 55 =
= 375 - 300 - 20 - 55 = 375 - 375 = 0
Answer;
1. ( x + 2 )
2. ( x - 5 )
Answer:

Step-by-step explanation:
It reveals what type of slope it has. It reveals whether it is positive or negative. It tells when the line will cross the Y-Axis. This is just the groundwork of it but there is a whole list I think on what one equation can reveal about a line on a graph. Hope This Helps! If you find any fault in my answer please let me know!
