If a number is rational, it can be written as a fraction. Can 15.07 be written as a fraction? Yes, as 15 7/100, so it is rational.
x = -3, y = -2
Substitute the values of x and y to the equation xy = k:
k = (-3)(-2)
k = 6
Lets get the negative reciprocal of the slope so we get

Now the equation that is perpendicular is

Lets solve for b by plugging in the point (x,y)=(6,1)

Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
Answer:
2625 kJ
Step-by-step explanation:
We assume the energy is proportional to the volume:
energy/volume = 1050 kJ/(500 mL) = E/(1250 mL)
Multiply by 1250 mL:
E = (1250/500)(1050 kJ) = 2625 kJ
The number of kJ in 1.25 L of Lemon Squash is 2625 kJ.
