Answer:

Each combo costed $4.95

Step-by-step explanation:

To solve, simply divide 103.95 by 21, and then put a dollar sign. (Most teachers would count no dollar sign as incorrect/points off, so don't forget it!)

103.95 ÷ 21 = 4.95 → $4.95

Solve F(x) for given domain. Include all of your work in your final work submit your solution
Ivahew [28]

Answer:

Step-by-step explanation:

Actually, you have not "given" the domain.

The domain of F(x)=x^2+2 is "the set of all real numbers," because F(x)=x^2+2 is a polynomial.

F(x^2) = (x^2) + 2 = x^4 + 2.  Again, this is a polynomial and the domain is "the set of all real numbers."

Double check to ensure that you have copied down this problem correctly.

How many solutions does the system have? <br> y=−2x+1 <br> y=−2x^2+1
balu736 [363]

Answer:

The system has two distinct solutions.

Step-by-step explanation:

The given system of equations are:


y=-2x+1--(1)

and

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


In order to determine the number of solutions the two equations have, we need to equate the two equations to obtain,



-2x^2+1=-2x+1


We now group all terms on the left hand side and equate everything to zero.

-2x^2+2x=0

x^2-x=0


This is now a quadratic equation in x^2 with a=1,b=-1,c=0.

At this stage we check the number of solutions using the discriminant.

D=b^2-4ac


\Rightarrow D=(-1)^2-4(1)(0)=1


Since the discriminant is greater than zero, the equation will have two distinct roots.

Therefore the system of equations has exactly two distinct solutions.


If you wish to see these solutions, you can continue as follows;

We factor x to obtain,

x(x-1)=0


\Rightarrow x=0,x-1=0



\Rightarrow x=0,x=1


When x=0,y=-2(0)+1


Then we have,

x=0,y=1


When x=1,y=-2(1)+1


Then we have,

x=0,y=-1


See graph

MATH HELP!!!
AfilCa [17]
1220*24 = 29,280 per year

multiply that by number of years until he retires:

761280 / 29280 = 26 years

292800 / 29280 = 10 years

the other 2 arent even years so it should be one of those 2. I would say the larger number
