The total cost, c, in dollars to create calendars for a fundraiser can be found using the function c=5.5u+25 where u is the number of calendars made. If there are at least 10 calendars made, what is a possible domain for this function? A: 10≤x≤100

B: {-12, -11, 12, 20, 50}

C: {10, 11, 12, 13, 14}

D: 0≤x<50

The correct option is;

{10, 11, 12, 13. or 14}

Step-by-step explanation:

The given function for the total cost, c, to create calendars is c = 5.5u + 25

The domain of a function are the values of the input variables of the function with which the output (the values) of the function are found

Therefore, the domain of the given function are the values of the variable, u, in the function

Where;

u = The number of calendars made

∴ When u ≥ 10, we have;

The possible domain for the function are u = 10, 11, 12, 13. or 14...

Therefore, the correct option is {10, 11, 12, 13. or 14}

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
