Am assuming the text of the problem is:
"At 6:00 p.m., the temperature was 55 Fahrenheit. At 11:00 p.m. that same evening, the temperature was 40 Fahrenheit. What real number represents the average change in temperature per hour?"
Average change in temperature per hour = (55 - 40)/(11 - 6)
Average change in temperature per hour = 15/5
Average change in temperature per hour = 3 Fahrenheit per hour
Answer:
$5
Step-by-step explanation:
48/12=4
1.25x4=5
Or you could set it up as a proportion
12/1.25=48/x
Answer: y=6^x-3
It is a exponent form of graph, so first:
y=a^x-b
When b=0, the asymptote is y=0 but as the asymptote given is y=-3, b=-3
Second:
the y value increases 6, when x changes 0 to 1, so a=6

Answer:
9/32
Step-by-step explanation:
BC = black circle
BS = black square
WC = white circle
WS = white square
Given:
(WC + WS) / (BC + BS) = 5 / 11
WC / WS = 3 / 7
BC / BS = 3 / 8
Find: (BC + WC) / (BC + BS + WC + WS)
Solve for WC and BC in the last two equations, then substitute into the first:
WC = 3/7 WS
BC = 3/8 BS
WC + WS = 5/11 (BC + BS)
3/7 WS + WS = 5/11 (3/8 BS + BS)
10/7 WS = 5/8 BS
WS = 7/16 BS
Therefore:
WC = 3/7 WS
WC = 3/16 BS
Substitute:
(BC + WC) / (BC + BS + WC + WS)
(3/8 BS + 3/16 BS) / (3/8 BS + BS + 3/16 BS + 7/16 BS)
(9/16 BS) / (2 BS)
9/32
