Equation:
Total cost = $4 + $2(admission)
y = 4 + 2x
Initial value:
when x= 1 (one admission)
y= 4 +2(1) =6
so, $6
Rate of change:

One number is eight more than a second number. Five times the first is 8 less than 2 times the second. Find the numbers.
The value of the first number is?
The value of the second number is?
Step-by-step explanation:
let the 2 numbers be x and y.
x - 8 = y --(1)
5x = 2y - 8 --(2)
sub (1) into (2):
5x = 2(x - 8) - 8
5x = 2x - 24
3x = -24
x = -8
sub x = -8 into (1):
y = -8 - 8 = -16
first number is -8 and second number is -16.

Answer:
63 miles / hour = 0.0175 miles / secondStep-by-step explanation:
63 miles per hour also equals 0.0108225108225108 feet per second.
Which does not really help you if you don't know how to convert feet per second to miles per second.
How to convert miles per hour to miles per second is fairly easy, with a calculator.
1 mile per hour equals 0.000277777778 miles / second,
and if you multiply 0.000277777778 by 63, you get = 0.01750000001
Which can be rounded to get 0.0175

solve 2v^2+4v=6 by factoring.
Answer:
v = 1 or -3
Step-by-step explanation:
2v^2 + 4v = 6
take 2 as common
2(v^2 + 2v = 3)
v^2 + 2v = 3
Now,
v^2 + 2v - 3 = 0
v^2 - v + 3v - 3 = 0
v(v - 1) + 3(v - 1) = 0
(v - 1) (v + 3) = 0
v = 1 or -3
Answer:
<=>v²+2v-3=0
<=>v²-v+3v-3=0
<=>v(v-1)+3(v-1)=0
<=>(v-1)(v+3)=0
<=>*v-1=0
v=1
*v+3=0
v=-3

Mike bought five items for lunch that cost a total of $4.55. Hot dogs cost $1.10 each and cookies cost $0.75 each. Which of these systems of equations below could be used to determine h , the number of hot dogs, and c , the number of cookies, Mike bought for lunch?
Answer:
1.1h+0.75c=4.55---------------1
h+c=5--------------2
Step-by-step explanation:
Step one:
given data
total lunch items= 5
let hot dogs be h
and cookies be c
cost of hot dogs = $1.10
cost of cookies = $0.75
total cost = $4.55
Step two:
The linear model for the total cost is given as
4.55=1.1h+0.75c---------------1
and the model for the number of items is
h+c=5--------------2
The systems of the equation for the situation is
1.1h+0.75c=4.55---------------1
h+c=5--------------2
