Answer:
Step-by-step explanation:
- 8x + 44 ≥ 60
Subtract 44 from both sides
- 8x + 44 - 44 ≥ 60 - 44
- 8x ≥ 16
Divide both sides by -8 and flip the inequality sign
-8x/-8 ≤ 16/-8
x ≤ -2
x = { ......... -4,-3,-2}
2) -4x + 50 < 58
Subtract 50from both sides
-4x + 50 -50 < 58- 50
-4x < 8
Divide both sides by -4 and flip the inequality sign
-4x/-4 > 8/-4
x > -2
x= {-1, 0 , 1 , 2....... }
Answer:
The hat cost £5 while the a shirt cost £6
Step-by-step explanation:
What I did was Guess and check until I finally found each of there amount.
The slope is negative and is -16 / 8 = -2
The y intercept is at y = 16
General form is y = mx + c
m = -2 and c = 16 so we have :-
y = -2x + 16 Answer
