Answer: 3. -x, y

Step-by-step explanation: we know that

A point reflected across the y-axis has this rule  

(a,b)------> (-a,b)  so if the center of the original circle was located at (x, y)  then  the center of the new circle after the transformation will be (-x,y)

bone-shaped treats are five for 3:50 at Shelly store in Sarah wants to buy 12 she set up and solve this proportion to find how m
Valentin [98]

Answer:

8.4 dollars

Step-by-step explanation:

The error is in the resolution of the proportion. In fact, the initial proportion is correct:

\frac{5}{3.5}=\frac{12}{x}

where x is the total cost. However, the following step of the resolution is wrong. In fact, the correct resolution is the following:

- Multiplying by x on both sides:

\frac{5x}{3.5}=12

- Multiplying by 3.5 no both sides:

5 x = 12 \cdot 3.5 \\5x = 42

And now we can find x:

x=\frac{42}{5}=8.4

So, the total cost is 8.4 dollars.

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as Daniel. How old is Kevin now?
GuDViN [60]
Let k and d be the Kevin's age and the Daniel's age;
We have the equation:
k = 3 + d;
k - 2 = 4( d - 2 );
We have 3 + d -  2 = 4d - 8;
Then, d + 1 = 4d - 8;
9 = 3d;
d = 3.
Finally, k = 6 years.

Please help urgently ​
lisabon 2012 [21]

Solving for y:

6y - 2x = 20

6y = 2x + 20

y = \frac{2x + 20}{6}

y = \frac{2x}{6} + \frac{20}{6}

y = \frac{1x}{3} + \frac{10}{3}

<em>Hope it helps!</em>
