2. Write the equation of the circle in general form

Anon25 [30]

(-1,-2) and (-1,4)
so these have same x values, but different y values, so these are on differnt sidef of circle

distanc between them is 6
6/2=3
radius=3

so move 3 units up from (-1,-2)
(-1,1)
so

if center is (h,k) and radius is r then
(x-h)^2+(y-k)^2=r^2

(-1,1) is center and r=3

(x-(-1))^2+(y-1)^2=3^2
(x+1)^2+(y-1)^2=9

Kevin runs a farm stand that sells apples and raspberries. Each pound of apples sells for $3.50 and each pound of raspberries se

krek1111 [17]

Kevin sold 10 pounds of apples and 20 pounds of raspberries.

Step-by-step explanation:

Given,

Cost per pound of apples = $3.50

Cost per pound of raspberries = $4

Total amount earned = $115

Let,

x represent the pounds of apples sold

y represent the pounds of raspberries sold

According to given statement;

3.50x+4y=115 Eqn 1

y = 2x Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$3.50x+4(2x)=115\\3.50x+8x=115\\11.50x=115$

Dividing both sides by 11.50

$\frac{11.50x}{11.50}=\frac{115}{11.50}\\x=10$

Putting x=10 in Eqn 2

$y=2(10)\\y=20$

Kevin sold 10 pounds of apples and 20 pounds of raspberries.

The above question was not written properly

Complete Question

Everyone loved the Chocolate eclairs and they all got eaten during the party. Mr Watson friend, James, ate 6/8 of them if there were 16 of the chocolates, how many did James eat?

Answer:

12 chocolates

Step-by-step explanation:

From the above question, we know that

Total number of Chocolates = 16

The fraction of Chocolate that James ate = 6/8

Therefore, the amount of chocolates that James ate is calculated as:

= 6/8 of 16 chocolates

= 6/8 × 16 chocolates

= 12 chocolates

Therefore, James ate 12 chocolates.
