Answer:
x ≥ −2
Step-by-step explanation:
This problem deals with inequalitites.
The expression is
x*2 ≥ −4
If we divide by 2 each side of the expression, we get
x* 2 / 2 ≥ −4 / 2
x ≥ −2
Which appears in your answer list
Answer:
y = -2x + 6
Step-by-step explanation:
2x + y = 6
Subtract 2x both sides
2x + y - 2x = 6 - 2x
y = -2x + 6
A^2 + b^2 = c^2
5^2 + b^2 = 20^2
25 + b^2 = 400
b^2 = 375
b = 19.4 feet

Answer:
Step-by-step explanation:
Let chocolate bar = c and blow pops = b
<u>As per given we have equations below:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Each chocolate bar costs $2.65
