The answer is -420 (negative four-hundred and twenty)
We are given with a circle and we need to find the <em>equation of the circle</em> , but first let's recall that , the equation of a circle with radius<em> 'r'</em> and centre at <em>(h,k) </em>is given by
Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here <em>(h,k) = (0,0)</em> .Which means that the centre is located at the point whose coordinates are<em> (0,0)</em> which is also known as origin . Now , finding the equation of the circle :-


<em>This is the required equation of Circle</em>
Answer: $205.33
Step-by-step explanation:
We know the original price was $234, during the sale there was a 35% discount, let's found out what that is...
234 * (100% - 35%)
234 * (65%)
234 * (0.65)
= 152.1
After the sale, the price was increased by 35%, remember percentages are out of 100...
100% + 35% = 135%
135% = 1.35
152.1 * 1.35
= $205.33
The price of the camera after the increase is $205.33, I hope this helps!
1. you didn't add anything
2. x>-4
Answer:
{(-34/7, -16/7)}
Step-by-step explanation:
Rearrange values, multiply to solve for x.
(5) 2y = 3x + 10
(-2) 5y = 4x + 8
Solve for x.
10y = 15x + 50 ↓
-10y = -8x -16
Combine and evaluate.
0 = 7x + 34
Subtract 34 from both sides.
7x = -34
Divide both sides by 7.
x = 
Plugin x value into either equation to solve for y.
2y = (3 ×
) + 10
2y =
+ 10
2y = 
y =
