Step-by-step explanation:
(i) 5 ≤ 2x − 4 ≤ 8 add 4 to all three expressions
9 ≤ 2x ≤ 12 divide by 2
9/2 ≤ x ≤ 6
(ii) −10 < (4 −3y)/− 5 ≤ 4 multiply all sides by -5
-20 ≤ 4 - 3y < 50 subtract 4
-24 ≤ -3y < 46 divide with -3
-46/3 < y ≤ 8
No. That's only true if x is less than ' 1 ', including anything negative. If x is more than +1, then the square is LESS than the cube.
Answer:
w = 36
Step-by-step explanation:
You can make a ratio 98 : 84 = 42 : w

49w = 1764
w = 36
Take the first graph and translate it UP 20 units.
