Answer:
Step-by-step explanation:
<em>Nothing can be done with the equation because there is no quotient. </em>
If there was, would be able to solve for x.
B because m=slope and if the equation goes y=mx+b the only answer would be B <span />
Answer:
<h2>
S = 250/t</h2>
Step-by-step explanation:
If the rate of change of sales is inversely proportional to the time t, this is expressed mathematically as ΔS ∝ 1/Δt
ΔS = k/Δt where k is the constant of proportionality
If ΔS = S₂-S₁ and Δt = t₂-t₁
S₂-S₁ = k/ t₂-t₁
If the sales after 2 and 4 weeks are 162 units and 287 units respectively, then when S₁ = 162, t₁ = 2 and when S₂ = 287, t₂ = 4.
On substituting this values into the given functions, we will have;
287 - 162 = k/4-2
125 = k/2
cross multiplying
k = 125* 2
k = 250
Substituting k = 250 into the function ΔS = k/Δt
ΔS = 250/Δt
S = 250/t
<em>Hence the value of S as function of t when the sales after 2 and 4 weeks are 162 units and 287 units, respectively is expressed as S = 250/t</em>
Answer:
4400 miles
Step-by-step explanation:
In 1 hour it can fly 1100/2 = 550 miles
Multiply that by 8 to find how far it can fly in 8 hours
8 *550 =4400 miles
Answer:
3 nights
Step-by-step explanation:
let n equal the number of nights
6 = 2n ---> 6 cm = 2 cm x the number of nights
6/2 = 2n/2 ---> divide both sides of the equation to isolate n
3 = n ---> number of nights equals 3
6 is the number of centimeters needed divided by 2 the number of centimeters per night which would give you the number of nights.
