Question

1) Find the constant of proportionality and the equation of variation :

a vary inversely b and b = 15, a = 10. Also, find b when a = 5.
2) Is the equation 0.4x - 2.3 = -0.5y linear?

If Yes, write its standard form and find at least one solution to it.
Pls answer this questions only if you know the answer please

Answer 1

Step-by-step explanation:

a) b and b = 15 & a = 10

if a = 5 than b = 7.5 as in question b and b means b+b.

2) no 0.4x - 2.3 = 0.5y is not linear
