X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
Answer:
xy=10
Step-by-step explanation:
Vary inversely means x and y have a constant product. The graph is not a straight line. We find the product from the given set of values a=2, b=5 to get ab=10. Therefore xy=10 is the equation.
2*-2*(12*3)-5*3
2*-2*(36)-15
2*-72-15
-144-15
-169
