Answer:
c. (-4, 0)
Step-by-step explanation:
F(X) = -3X - 4
Y = -3X-4
SWAP X AND Y: x = -3y -4
y = -1/3x - 4/3
f⁻¹(x) = -1/3x - 4/3
point (-4,0): x = -4 y = f⁻¹(-4) = (-1/3)*(-4) - 4/3 = 4/3 - 4/3 = 0
When zero is added to or subtracted to a number, the number is not affected.
Answer:
A ; y = 2229-x
Step-by-step explanation:
The question is asking for us to find how many seats are left that can be sold. There are 2463 total seats, 234 reserved seats, and x non-reserved seats.
If we subtract the 234 reserved seats from total seats, we will get 2229, the number of non-reserved seats and the not sold seats.
Since x is the non-reserved seats, we can subtract x from 2229 to get the number of seats that aren't sold.
The equation that represent the value of Alizeh’s investment after 20 years is y = 1000(b)^20
<h3>Exponential equation</h3>
The increase in the amount of his money can be represented using the exponential function as shown:
y = ab^x
Given the following
a = 1000
x = 20 years
Substitute
y = 1000(b)^20
Hence the equation that represent the value of Alizeh’s investment after 20 years is y = 1000(b)^20

Answer:
70th percentile for the amount of time between customers entering is 30.10
Step-by-step explanation:
given data
mean = 25
to find out
What is the 70th percentile for the amount of time between customers entering Clay's store
solution
we know that here mean is
mean = 
..................1
so here 25 =
and we consider time value corresponding to 70th percentile = x
so we can say
P(X < x) = 1 - 
P(X < x) = 70 %
1 - 
= 70 %
1 - 
= 0.70
= 0.30
take ln both side
= ln 0.30
= 1.203973
x = 30.10
70th percentile for the amount of time between customers entering is 30.10
