Answer:

B(x+2)^2+y^2=16

Step-by-step explanation:

since you have an x-coordinate only and it is negative and a y coordinate which is 0..basically x will appear positive with its conjecture x^2 and the y value will be independent...y^2...bare in Mind that radius is always squared hence it is 16 instead of 4

Seriously someone help me i answered it but i don’t know if it is right so please tell me if it is and how i got the answer or p

Answer:

<h2>C</h2>

Step-by-step explanation:

To determine a function rule, look at the table. Input the x and y value from one column into the function to see if it is correct.

<h3>Function a: y = 10 - 2x</h3>

Input values

22 = 10 - 2(6)

22 = 10 - 12

22 ≠ -2 ❌

As we can see, function a gives us a false statement, so a is incorrect.

<h3>Function b: y = 2 - 10x</h3>

Input values

22 = 2 - 10(6)

22 = 2 - 60

22 ≠ -58 ❌

We once again get a false answer, so b is also not correct.

<h3>Function c: y = 10 + 2x</h3>

Input values

22 = 10 + 2(6)

22 = 22 ✔

Finally, we get a true statement, so option c is correct.

<h3>Function d: y = 2 + 10x</h3>

Just to check that option c is correct, we need to prove that d is incorrect.

Input values

22 = 2 + 60

22 ≠ 62 ❌

This is also wrong, so that proves that c is correct.

I'm always happy to help :)

mamaluj [8]

Answer:

72

Step-by-step explanation:

If you take s + 19 = 8s - 100 , you will get 17, so s = 17. Plus 17 into 4s + 4 and you will get 72. DC = BE, so BE = 72.

Chase baked 4/5 dozen brownies in 3 hours ? What is her average of baking per hour ?

loris [4]

Answer:

$3\frac{1}{5}$ brownies per hour

Step-by-step explanation:

Given parameters:

Number of brownies = $\frac{4}{5}$ of a dozen

Time taken = 3hrs

Unknown:

Average baking per hour = ?

Solution:

The average baking per hour;

This is a rate problem;

Average baking per hour = $\frac{number of baking}{time}$

Number of brownies = $\frac{4}{5}$ x 12 = $\frac{48}{5}$

Average baking per hour = $\frac{48}{\frac{5}{3} }$

= $\frac{48}{5} x \frac{1}{3}$

= $\frac{16}{5}$

= 3 $\frac{1}{5}$ brownies per hour
