Since the symbol tells us the angle is 90 degrees we know the 4x and 5x add up to make 90 degrees.
Lets use this to make and form an equation
5x + 4x = 90
9x =90 (collect the x values)
x = 10 (divide both sides 9 to find what x is)
Sorry but the question don't pop up for me
To answer this question, start by identifying the total amount of income after 5 years for the first contract.
Since you start with 15,000 and get 1000 more each year, write an expression that represents this relationship.
15000 + 1000(5)
Multiply the parenthesis to begin to simplify your expression.
This leaves you with:
15000 + 5000
Add to find the total salary after five years with the first contract.
This ends up with:
$20,000
For the second contract, you have a diffferent rate of increase. Start by finding what one percent of the initial salary is. To do this, divide 14000 by 100.
14000/100 = 140
Then to find ten percent, multiply that number by 10.
140 x 10 =1400
So, each year you add 1400 dollars to the salary.
Now, using this information, set up an expression to model the salary for contract 2 after 5 years.
This should leave you with:
14000 + 1400(5)
Begin to simplify by multiplying what’s in the parenthesis.
1400 x 5 = 7000
Now rewrite your expression:
14000 + 7000
Add to find the total salary after 5 years with contract 2.
14000 + 7000 = 21000
So the salary with contract 2 is $21,000.
So, since $21000 is $1000 more than just $20000, contract 2 is the better option. I hope this helps! :)
