Answer:
(2, 13)
Step-by-step explanation:
Since they both equal y, you can equal them to each other.
8x - 3 = 2x + 9
Subtract 2x from both sides.
6x - 3 = 9
Add 3 to both sides.
6x = 12
Now divide 6 on both sides.
x = 2
Now that we have found x, we need to find y. Just plug in x to the equations.
y = 2(2) + 9
y = 4 + 9
y = 13
Now, if the next equal has the same y, then both are true.
8(2) -3 = y
16-3=y
13 = y
So therefor, both x and y are true.
Answer:
The value of k for the expression to be undefined is 9 .
Step-by-step explanation:
Given as :
The rational expression is written in the form
Now, according to question
The expression to be undefined , denominator should be 0
<u>As, 
is infinite ( ∞ ) term and it is undefined , so for expression to be undefined , the denominator should be 0</u>
∴ k² - 18 k + 81 = 0
Or, k² - 9 k - 9 k + 81 = 0
Or, k ( k - 9 ) - 9 ( k - 9) = 0
Or, ( k - 9 ) ( k - 9 ) = 0
Or, ( k - 9 ) = 0 , ( k - 9 ) = 0
∴ k = 9
So, The value of k = 9
Hence The value of k for the expression to be undefined is 9 . Answer
Answer:
$200
Step-by-step explanation:
First Change the percent to a decimal
In this case the percent was %8, change it into a decimal; 8%=.08
Next multiply 2,500 x .08 which gives you 200
The answer is $200! Hope this helps!.
Answer:
A = P ( 1 + r / n) ^( t * n)
where
A = the amt owed
P = amt borrowed
r = the interest rate as a decimal
n = the number of compoundings per year
t = the number of years
A = 10000 ( 1 + .10 / 2)^(2 *1) = 10000 ( 1.05)^2 = $11025
Step-by-step explanation:
Your answer is $1620.
To solve this, first look at what we're given. $324 is spent a month on fuel, and fuel is 20% of their income. Therefore, $324 is 20% of the family's income per month.
Now, to solve this, we're looking for 100% of the family's income. 20% is 1/5 of 100%, so therefore $324 is 1/5 of the family's full income.
To get 100%, then multiply 20% by 5 to get 100%, and therefore multiply $324 by 5 to get the full income.
$324 * 5 = 1620, or your answer.
Good luck!
