Ineed with question 15 parts a b and c

(a)

let m represents renting movie and c represents the total cost of buying a rental card.

As per the given statement: A video store charges $10 for a rental card plus $2 per movie.

⇒ c(m) = 2m + 10                      ......[1]

which implies that this equation represents the slope intercept form(i.e y = ax+b) where 2 is the slope and a y-intercepts of 10.

(b)

Graph of the given equation:

c(m) = 2m + 10

you can see in the figure given below.

(c)

now, to find the cost of buying a rental card and renting 6 movies.

⇒ m = 6 [ as m represents renting movie]

Substitute this m =6 in equation [1];

c(6) = 2(6) + 10

c(6) = 12 + 10

c(6) = 22.

Therefore, the total cost of buying a rental card and renting 6 movies is, $22.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
