Answer:
There is no solution to this system.
Step-by-step explanation:
The left side of the first equation is 3 times the left side of the second one.
If we multiply the whole of the second equation by 3 we get:
3x - 6y = -16.
As the first equation is 3x - 6y = -12 we see that there is no solution to this system. 3x - 6y can't be equal to -12 and -16.
Answer:
Monday: 4 hours = $36
Tuesday: 6 hours = $54
Wednesday: 5 hours = $45
His earnings are proportional because, for each hour, Richard earns $9. Using the formula y = kx, k (the constant) is always the same:
- 36 = k × 4 (k = $9)
- 54 = k × 6 (k = $9)
- 45 = k × 5 (k = $9)
Hope this helps!
Gym B should be cheaper by $20 if you go the same number of times.
X>=-4 so x is greater than or equal to -4
