It's saying that on every other stop(with even numbers)you add 2 people, and on all the other stops(odd numbers)you subtract 5 people. Be sure that you start with 18 people on the bus! Keep doing this until there is no more people on the bus!
Answer:
B
Step-by-step explanation:
Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis. This function 
has been moved up 5 units so its asymptote is at y=5. This means the function never goes below 5 in its y-values.
The x values are not affected and all are in the function. This is the domain. So the domain is (-∞, ∞).
The y values are affected and are y > 5. This is the range and it is written
(5, ∞).
Option B is correct.
Answer:
y=3,x=1.3,z=6.2 :)
Step-by-step explanation:
y=3,x=1.3,z=6.2 :)
So, we have:
: x+y+z=10 [equation 1]
: 5x+3y=14 [equation 2]
: x−2y+z=2.5 [equation3]
(I'm going to assume that you know how to solve equations with 2 variables)
1. eliminate a variable to get 2 variables
Let's reverse equation 2:
-x+2y-z= -2.5
and take equation 1, to try to eliminate "z"
x+y+z=10
add up the 2 equations to get:
3y=7.5
and solve to get
y=2.5
2. substitute what we already solved into another equation
Luckily, equation 2 only has 2 variables, and one is y, so we can sub it in.
5x+3y=14 --> 3x+3(7.5)=14
solve to get
x=1.3
3. Substitute both of our variables in to get the final variable: z
Let's take the first equation.
x+y+z=10 --> 1.3+2.5+z=10
solve to get
z=6.2
I hope this helps you!
Answer:
the lines are perpendicular
Step-by-step explanation:
if they are perpendicular the products of their gradients would be -1
the gradient of y=-x-6 is -1
the second equation needs to written to conform to y=mx+c
hence, 3x-3y=9
3x-9=3y
y=3x-9/3=x-3.the gradient of this line is 1
1x-1= -1
