What are the center and radius of a circle defined by the equation x^2+y^2- 6x+ 8y+ 21=0?
Natali5045456 [20]
You have to complete the square. When you do this you get an equation that looks like this: (x-3)^2 + (y+4)^2 = 4. So your center is (3, -4) and your radius is 2. That looks like B to me!!!

The Nair family has collected 2,400 pennies. The pennies will be divided evenly among the 4 children. How many dollars will each
goldenfox [79]
You must divide 2400 by 4 to find your answer. If you know 24/4, then it should be easy. 24 divided by 4 is 6, so add those 2 zeros and you should get 600 pennies for each student.

serg [7]

Answer:

1 taco costs $1.5 and 1 burrito costs $3.25

Step-by-step explanation:

-Let t denote tacos and b denote burritos.

-The system of equations in the two weeks can then be expressed as below:

8t+5b=28.25\ \ \ \ \ \ ...i\\\\7t+7b=33.25\ \ \ \ \ \ ...ii

make t the subject of the formula in i and then substitute in ii to solve for both unknowns:

8t=28.25-5b\\\\t=\frac{1}{8}(28.25-5b)\\\\\\\therefore 7t+7b=33.25\\\\\frac{7}{8}(28.25-5b)+7b=33.25\\\\\\24.71875-4.375b+7b=33.25\\\\8.53125=2.625b\\\\\\b=3.25\\\\t=\frac{1}{8}(28.25-5\times3.25)=1.5

Hence, 1 taco costs $1.5 and 1 burrito costs $3.25
