At an electronics store, a $165 television is marked up 110%. Dave purchases the TV and must pay 6.5% sales tax. What is his fin
Mariana [72]
Firstly, we need to know the price of the TV after the 110$ increase.
     $165 x 1.10 = $181.50
[This is an increase of $16.50]
[1.10 is the equivalent of 110%. 1 being 100% and the .10 being 10%]

Now for the sales tax. We apply a similar method.
     $181.50 x 0.065 = $11.79
     6.5% of $181.50 is $11.79, so we add the two together to find the final cost.

The final cost of the TV is $193.29

What is the sum of 52 and its additive inverse?
Lisa [10]
Hello there!

The additive inverse of any number just means to flip it's value.

For example;

The number "3" would have an additive inverse of "-3".
The number "-15" would have an additive inverse of "15".

Since we have "52", we can flip the value sign of it.
We now have -52 and 52.

Since the question asked us to sum our numbers, we need to add them.

-52 + 52 = 0

The sum of 52 and its additive inverse is 0. 

 I hope this helps!

Korvikt [17]
-1(x+2)=2(3x-6)
-1(x+2)=2(3x-6)distributhing -1 through parantheses
-1x+(-1)*2=2(3x-6)
-x-2=2(3x-6) distributhing 2 through parantheses
-x-2=2*3x-2*6
-x-2=6x-2*6
-x-2=6x-12    add x 
-2=6x-12+x
-2=7x-12        add 12
-2+12=7x
10=7x       divide by 7  
x= \frac{10}{7}

Question 1 (10 points)
Irina18 [472]

Answer:

Q1 d, Q2 c, Q3 d

Step-by-step explanation:

Q1

g(x)=-3x+1

g(x)=16 means that

-3x+1=16 subtract 1 from both sides

-3x=16-1 combine like terms and divide both sides by -3

x=-15/3=-5

Q2

g(x)=3x²+4x-1

g(2) means that x=2 so substitute

g(2)=3*2²+4*2-1=12+8-1=19

Q3

domain are the x values

range are the y values
