We see that we have some nasty sqrt signs
try to use x values that yield perfect squares inside the sqrt sign like 1,4,9,16, or ones that make the inside 0
first one
y=-4+√(x+2)
try some nice values for ease of graphing
ok so try x=-2
y=-4
(-2,-4)
x=-1
y=-3
(-1,-3)
x=-1
y=-3
(-1,-2)
if x=7
y=-1
(7,-1)
if x=14
y=0
(14,0)
so we have
(-2,-4)
(-1,-3)
(2,-2)
(7,-1)
(14,0)
second one
y=2+√(x+1)
if x=-1
y=2
(-1,2)
if x=0
y=3
(0,3)
if x=3
y=4
(3,4)
if x=8
y=5
(8,5)
we have
(0,3)
(-1,2)
(3,4)
(8,5)
first one
y=-4+√(x+2)
so we have
(-2,-4)
(-1,-3)
(2,-2)
(7,-1)
(14,0)
second one
y=2+√(x+1)
(0,3)
(-1,2)
(3,4)
(8,5)
Let the number of hours the ski jet was rented be x, then
For company A, Cost = 2.25x + 24
For company B, Cost = 2.75x + 23
Fro the cost to be the same: 2.25x + 24 = 2.75x + 23
2.75x - 2.25x = 24 - 23
0.5x = 1
x = 1/0.5 = 2
x = 2
The cost are the same after 2 hours.
Add the cost of your sweater, cost of your jacket and cost of your socks together. Then subtract that from $125. Then whatever your answer is divide that by $22.50 and you will find out how many pairs of shoes you can buy.
Answer:
B
Step-by-step explanation:
The domain is the x axis and if you look at the x axis it shows up to 11 months. So that means that the domain shows flower production up to 11 months
The mean cannot be greater than the greatest value in the data set. The mean is the average of the data set, and it doesn't make sense for the average to be higher than everything.
Hops this helps!
