Are the graphs of the lines in the pair parallel? Explain. y = 6x + 9 27x – 3y = –81
2 answers:
Answer:
the answer is No, because the slopes are not the same
Step-by-step explanation:
in the equation: y=6x+9
the slope is 6
in the equation: 27x - 3y= -81
the slope is 7
the slopes are NOT the same
For the 2nd equation, you need solve for y to get it by itself so once thats done you get y=9x+27 but since the x values (also the slope) aren't equal, they can't be parallel

Step-by-step explanation:
36 + b > -24b + (-64)
24b + b > -36 - 64
25b > 100
b > 100/25
b > 4
Answer:
11.61 in
Step-by-step explanation:
the screen when divided diagonally, forms 2 right triangles
diagonal = hypotenuse = 16
16^2 = 11^2 + w^2
w^2 = 135
w = 11.61
