Statement 1 is false.

While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function. It would not be a function if some of the x-values had more than one corresponding y-values.

Statement 2 is true.

The domain of a function is all the x-values it encompasses. This function starts at 3 and ends at 8.

Statement 3 is false.

The range of a function is all the y-values it encompasses. This includes all the y-coordinates, but it does not express the range properly. The range is [6, 10].

Hope this helps!!

Gym membership costs $100 per year in a $2 fee per visit another gem charges $12 fee per visit with no yearly membership find th

Nimfa-mama [501]

Answer:

For 10 visits, both gyms charge the same

Step-by-step explanation:

Equations

Gym memberships' costs are:

G1 = 100 + 2x

G2 = 12x

Where x is the number of visits to the gym.

We need to find the number of visits for which the charges for both gyms are the same. Thus equating the costs:

12x = 100 + 2x

Subtracting 2x:

10x = 100

Dividing by 10:

x =10

For 10 visits, both gyms charge the same

miskamm [114]

Answer:

$L=1+20i$

$B=3+20i$

Step-by-step explanation:

From the question we are told that:

Area $A=440cm^2$

Generally the equation for For Area is mathematically given by

$A=L*B$

$A=x*(x-2)$

Therefore

$x^2-2x-440=0$

$x=1+20i$

Therefore The Dimensions are

$L=1+20i$

$B=1+20i+2$

$B=3+20i$

Simplify the expression: 2(5a - 4a ) + 6a

miv72 [106K]

Hello from MrBillDoesMath!

Answer: 8a

Discussion :

Let's study the expression:

2(5a - 4a) + 6a

The boldfaced term simplifies to "a" as 5 = 4 = 1. So the expression becomes

2a + 6a

As 2 + 6 = 8, 2a + 6a = 8a.

What is 802.6 in expanded form

ankoles [38]

Answer:

802+6 tenths.

Step-by-step explanation:

802 is not apart of the decimal. (I might sound stupid but I dont remember expanded form as much.) Only the 6 is apart of the decimal itself. 802 is just numbers. The 6 is pretty much the decimal.
