C=300+1200x-100x. Find x if the total cost is 3,000
3,000 = 300 + 1200x -100x
3000 = 300 + 1100x
2700 = 1100x
2700÷1100=x
x=27/11
x = 2 5/11
Round to 3
A)
x 0 1 2 3 4
y 5 10 15. 20. 25
b) x 0 1 2 3. 4
y 1. 10. 37. 82. 145
Answer:
x ≥ -4
Step-by-step explanation:
-3x + 2 ≤ 14
Subtract 2 from each side
-3x+2-2 ≤ 14-2
-3x ≤ 12
Divide each side by -3 . Remember that dividing by a negative flips the inequality.
-3x/-3 ≥12/-3
x ≥ -4
Multiply 1.34 m by 6 and you will get 8.04 m. Then you will subtract 8.04 m from 24.5 m and your final answer will be 16.46 m.
