Step-by-step explanation:
Change it into this
(2x-3)(2x-3)
Then multiply the insides and outsides and add them
(2x*2x) + (2x* -3) + (-3*2x) + (-3*-3)
Simplify
4x^2 - 6x -6x + 9
Simplify again
4x^2 - 12x + 9
Answer:
Equation: Y=8x+9, y-intercept: (0,9)
Step-by-step explanation:
An equation is set up in the format of y = mx+b, so simply plug the appropriate numbers in for those variables.
The number of words james can type in 6 minutes at the same rate is 360 words
Given:
Number of minutes to type 150 words = 2.5 minutes
let
number of words James can type in 6 minutes = x
Equate the ratio of the number of words to number of minutes
150 : 2.5 = x : 6
150/2.5 = x/6
cross product
150 × 6 = 2.5 × x
900 = 2.5x
x = 900/2.5
x = 360 words
Therefore, the number of words james can type in 6 minutes is 360 words
