-4,2
Step-by-step explanation:
a reflection across the y axis means the y values stay the same and the x values change sign
Answer:
Perpendicular lines are lines that intersect at right angles.
Step-by-step explanation:
I'm assuming that your question is asking what the term is for two lines that intersect at a right angle. If I'm correct then your answer is perpendicular lines.

Answer:
The new volume is 20litres
Step-by-step explanation:
This problem bothers on the expansion of gases
According to Boyle's law
The volume of a given mass of gas at constant temperature is inversely proportional to the pressure
P∝1/v
Pv= constant
Given data
P1= 1.5atm
v1 = 10 litter
P2=0.75atm
v2=?
Applying P1v1= P2v2
v2= P1v1/P2
v2= 1.5*10/0.75
v2= 15/0.75
v2= 20litres
(y^2 + 7y +12) / (y^2+8y +15)
factor both equations:
(y+3)(y+4) / (y+3) (y+5)
cancel out common factors to get:
y+4 / y+5
