Answer:
- One solution: (0.4, -4.8)
Step-by-step explanation:
<u>Given equations</u>
This system has one solution since the two lines represented by the equations have different slopes.
<u>Solution:</u>
- -2x - 4 = 1/2x - 5
- -2x - 1/2x = -5 + 4
- -2.5x = -1
- 2.5x = 1
- x = 1/2.5
- x = 0.4
<u>And y is:</u>
<u>The point is:</u>
Answer:
14x+ 61
Step-by-step explanation:
5+ (14x+56)
14x+ 56+5
14x+61
Answer: 1 : -5x + 3y = 2 Equation 2 : -5x - 5y = -30 Because both equations the system of equations by elimination.
Another way to figure the cost is $2.50 plus $0.50 per hour.
For 8 hours, the cost is $2.50 +8*$0.50 = $6.50.
The correct answer is 2.4
