Answer:
When x = 5, y = 8.
Step-by-step explanation:
y is inversely proportional to X.
This means that we solve this using the rule of three for inversely proportional variables, that is, we apply line multiplication instead of cross multiplication.
y = 20, x = 2
Work out y when x = 5
20 - 2
x - 5
Applying line multiplication



When x = 5, y = 8.
the answer for number 6 is 5.7
Answer:
79665
Step-by-step explanation:
26555 + 26555 is 53110 then add 26555 again at it equals 79665
O All real numbers is the range of the function
(2/5)(x-1)<(3/5)(x+1) perform indicated multiplications
(2x-2)/5<(3x+3)/5 multiply both sides by 5
2x-2<3x+3 add 2 to both sides
2x<3x+5 subtract 3x from both sides
-x<5 divide both sides by -1 (remember to reverse direction of inequality sign when multiplying/dividing by a negative value)
x>-5
