Could use some help with answering this. :)

Mathematics
1 answer:
Tpy6a [65]3 years ago

Answer: r = 2

Step-by-step explanation: The general equation is:

(x-a)² + (y-b)² = r²

where (a,b) = coordinates of the center, and r = radius

x² + y² = 4 is the same as

(x-0)² + (y-0)² = 2²

So, the center is at (0,0) and the radius is 2.

The produce market is having a sale on grapes and oranges. A customer found the following two receipts in her cart as she was wa
AleksandrR [38]

Answer:

Step-by-step explanation:

From the first receipt:

2 pounds of grapes + 4 pounds of oranges = 10.70 which, in an algebraic equation, looks like this:

2g + 4o = 10.70

From the second receipt:

3 pounds of grapes + 2 pounds of oranges = 9.65 which, in an algebraic equation, looks like this:

3g + 2o = 9.65

Putting those together into a system and solving using the elimination method:

2g + 4o = 10.7

3g + 2o = 9.65

I am going to eliminate the oranges first since it's easier to do that. I will multiply the second equation by -2 to get a new system:

2g + 4o = 10.7

-6g - 4o = -19.3

As you can see, the oranges are eliminated because 4o - 4o = 0o. That leaves us with only the grapes:

-4g = -8.6 so

g = 2.15

Grapes cost $2.15 per pound. Now sub that into either one of the original equations to solve for the cost per pound of oranges:

2(2.15) + 4o = 10.7 and

4.3 + 4o = 10.7 and

4o = 6.4 so

o = 1.60

Oranges cost $1.60 per pound. That is choice D from your list.

If 3(x - 4) = x + 4, then x =8
Greeley [361]

Answer:

Valid

Step-by-step explanation:

3(x-4)=x+4              <em>Given</em>

3x-12=x+4                <em>Distribute</em>

2x=16<em>                      Subtract x from both sides and add 12 to both sides</em>

x=8                           <em>Divide each side by 2.</em>
