QUESTION:
When you factor a little perfect square trinomial, which pattern results?
ANSWER:
[2] The square of a binomial pattern.
EXPLANATION:
<u>Squaring a binomial creates a perfect square trinomial</u>:–
You need an equation system.
First, translate the text into equations :
y = total price for the bike
x = number of months
first bike :
y = 25x + 500
second bike :
y = 50x + 200
Then you have to solve the system by placing the two equations side by side and comparing them.
25x + 500 = 50x + 200
Solve to find the value of x
Answer:
Step-by-step explanation:
Y= -3x + 4..........(1)
Y= 4x - 10...........(2)
Substituting (1) into (2)
-3x + 4 = 4x - 10
-3x - 4x = -10 - 4
-7x = -14
x = -14/-7
x = 2
Putting x in (2)
y = 4(2) - 10
y = 8 - 10
y = -2
