Let's say that x represents hours that Elizabeth volunteers over 1 week. Katie volunteers x+3 and Siobhan x-1 hours per week. The equation that arises from condition in text is:
3*(x+3) = 3*(x + x-1)
x+3 = 2*x - 1
2*x - x= 3+1
x=4.
Elizabeth volunteers 7 hours
Katie volunteers 4 hours
Siobhan volunteers 3 hours
Answer:
4,5,6 / 6,8,10 / 5,12,13 / ....
Step-by-step explanation:
Base on the pythagorean theorem, we have : a² + b² = c².
The first set : 4,5,6 - 4² + 5² = 6² (a possible set)
The second set : 6² + 8² = 10² (another possible set)
The last set : 5² + 12² = 13² (also possible)
There are a lot more sets, but I'll only list 3. Hope this helps :)
Answer:
y = 4/7x - 4
Step-by-step explanation:
You first have to put it in y = mx + b form
So, we first subtract 4x from both sides: -7y = -4x + 28
Divide both sides by -7
y = 4/7x - 4
Now to graph you have to start at the starting point which is -4
So we start with our point on -4 then move up 4 times and 7 times to the left. Mark the points then draw your line!
