Answer:
The monthly cost = $9 + $0.39x
Step-by-step explanation:
ANSWER: y + 6 = 3/4(x + 4)
Slope Form: y - b = m (x - a)
m = slope
(a, b) = given pair of points (in this case ‘(-4, -6)’)
Answer:
x=-3.5
Step-by-step explanation:
14/-4 = -3.5
Answer:
D = {-2, 0}
Step-by-step explanation:
If the range is {-3, 1}, that means -3 and 1 are <em>images</em> of some points a, b in the domain. So, there are two points a, b in the domain such that:
g(a) = -3 and g(b) = 1
If g(a) = -3 then 2a + 1 = -3 ------>2a = -4 ------> a = -2
If g(b) = 1 then 2b + 1 = 1 ------> 2b = 0 ------> b = 0
Hence D = {-2, 0}
