As time goes up, the number goes down
therefor we have an exponential function
we take 2 points (0, 25,000) and (1, 23,750) and use our trusty TI and find the equation
equatin is y=25000(0.95^x) or
f(x)=25000(0.95^x)
Answer:
check the explanation
Step-by-step explanation:
Define the number of the items multiply
To find weight per item:
This is the equation
x/4 - 9 = 5
+ 9 + 9
x/4 = 14
*4 * 4
x = 56
Answer:
$200
Step-by-step explanation:
To solve this problem, we need to figure out what 10% of $2,000 is. To do that, we simply multiply $2,000 by 10%. Don't forget to change 10% to its decimal form (10% -> 0.10). The work is shown below:
($2,000)(0.10) = $200
This means that the shipping for the computer and printer costed Eric $200.
Two angles are complementary angles if they have a sum of 90 degrees. We could write the expression as below.
angle 1 + angle 2 = 90
7x + 2 + 3x - 2 = 90
solve for x by adding like terms
7x + 3x + 2 - 2 = 90
10x = 90
x = 90/10
x = 9
The value of x is 9
