Answer:
a=0
Step-by-step explanation:
x²-2x+y²-4y-4=0
(x²-2x+1)+(y²-4y+4)-9=0
(x-1)² + (y-2)² = 3²
Center: (1,2) radius: 3
(1,2) on line 2x-y+a=0
2*1 - 2 + a = 0
a = 0
Answer:
2/5y and -0.2y
-6 and -2
Step-by-step explanation:
Here, we want to select the pair of like terms
To do this, we finish the evaluation of the expression
2/5y + 1/5x - 0.2y -6+ (-2)
We have the two y’s together
2/5y and -0.2y
-6 and -2
Answer:
71.5
Step-by-step explanation:
x+1 so (1+10) x (21+5)= 286
but then 1+1=2 and 2x2= 4 so 286 divided by 4= 71.5
Answer:
A. $2,000
Step-by-step explanation:
Let x represent Caitlin's monthly income and y represent Tim's monthly income.
We have been given that Caitlin has a car payment of $300 per month, which is 10% of her monthly income.
We can represent this information in an equation as:




Therefore, Caitlin's monthly income would be $3000.
We are also told that after Caitlin is married to Tim, her car payment will only be 6% of their combined monthly income.
This means that 6% of x plus y is equal to 300.







Therefore, Tim's monthly income is $2,000 and option A is the correct choice.
Hi there!
Here are all the steps into isolating "X" :
+ 3 = 6 + 1
+ 3 = 7
Subtract 3 from each side of the equation
= 4
Multiply each side of the equation by 10
x = 40
There you go! I really hope this helped, if there's anything just let me know! :)
