A jeweler orders necklaces from a website that offers $6 shipping for any-size order. Each necklace costs $7. The jeweler wants to know the total cost of ordering n necklaces.

What is the independent (input) variable?

✔ n, the number of necklaces

What is the dependent (output) variable?

✔ c, the total cost (in dollars)

What is the domain?  

✔ n=0, 1, 2, 3,...

Which equation expresses the order’s total cost, c, as a function of the number of necklaces, n?

✔ c(n)=7n + 6

Which expression means “the total cost, including shipping, of 5 necklaces”?

✔ c(5)

Step-by-step explanation:

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.
