Find the point of intersection of the lines: y = 4x + 1 and y = – 2x + 4 A. (2 , 9) B. ( 1 2, 3 ) C. (1 , 2) D. ( 1 4, 2)
1 answer:
Answer:
B. (1/2, 3)
Step-by-step explanation:
It is perhaps easiest to try the point values in the equations.
A — 4·2+1 = 9; -2·2 +4 ≠9 . . . . not the answer
B — 4·1/2 +1 = 3; -2·(1/2) +4 = 3 . . . . this is the answer
we need go no further since we have the answer

Hello!
First, we need to find the unit rate.
72 divided by 2 = 36.
36 x 9 = 324.
There were 324 pieces of paper to start with.

x^2 = 2x + 15
x^2 -2x - 15 = 0
Factor:
(x-5)(x+3) = 0
x = 5 or x = -3
The temperature went from -3 to 16. The difference between the two numbers (16- -3) = 19 degrees Fahrenheit.
I hope this helps!
