Answer:
Step-by-step explanation:
In this problem we have a exponential equation of the form
where
y is the population of the city
x is the number of years
a is the initial value or y-intercept
b is the base
r is the rate of growth
b=(1+r)
we have
substitute
For x=17 years
substitute the value of x in the exponential equation and solve for y

Answer=63
Answer: $27.50
Explanation:
4 students + 8 friends = 12 people altogether
$330.60/12 = $27.50
Therefore, it’s going to cost approximately $27.50 per person.
Answer:
Step-by-step explanation:
From given information
P_{A} = 50 /120 = 0.4166667
P_{B} = 80 /120 = 0.6666667
P_{C} =48/120 = 0.4
Ha : p > 0.4
Correct order is
Answer : C) B ,A ,C
y=3x
Step-by-step explanation:
y=3x-5
but
m=x+5/3
replace m in 3m to 3(x +5/3)
i.e
y=3(x+5/3)-5
y=3x +5-5
y=3x
