Do the equations y=3x+5 and y=3x-5 have no, one or many solution(s)?

Y=3x+5
y=3x-5
(I remember that paralell lines have same slope and paralell lines with different y intercepts have no solutions so I wuld say no solutions)
I will solve
set them eaqual to each other
3x+5=y=3x-5
3x+5=3x-5
subtract 5 from both sides
3x=3x-10
subtract 3x from both sides
0=-10
false
there is no solution

They will have no solutions. since the slope (3x) of both equations are the same and they have different y-intercepts (-5 and +5) these lines are parallel and will never intersect

ANSWER:

We have to find new side-lengths of PQR triangle.

Original sides are.

$\begin{gathered} PQ\text{ = 8cm} \\ QR=17\operatorname{cm} \\ RP=15\operatorname{cm} \end{gathered}$

After multiplying by 2.5 we get

$\begin{gathered} PQ^{\prime}=2.5\times PQ=(8\times2.5)cm=20\operatorname{cm} \\ QR^{\prime}=(17\times2.5)cm=42.5\operatorname{cm} \\ RP^{\prime}=(15\times2.5)cm=37.5\operatorname{cm} \end{gathered}$

These are the new sides of the P'Q'R' triangle.

Which is bigger 2/5 or 4/9

Jlenok [28]

The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.

2/5 = 18/45
4/9 = 20/45

Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
