Answer:
(-4.666667, -3.16667)
Step-by-step explanation:
(-4 2/3, -3 1/6)
D is the answer because if you calculate the answer correctly. that will be so.
A) Business means the process of earning money, so she earned $350 at first time, so her initial value would be: $350
Rate of change = 750 - 350 / 350 * 100
= 400 / 350 * 100
= 40000 / 350
= 114.28
Now, There are 4 years between 2014 & 2010 so it will be:
= 114.28 / 4 = 28.57
In short, Your Answer would be 28.57% per year
B) Equation would be: Y = x + 0.2857x
Where, x = number of year
Hope this helps!
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
Answer:
- The equation 2n = p should be 2p = n.
- The actual cost of the onions is $3.00 per pound.
- Potatoes cost $1.50 per pound.
Step-by-step explanation:
The wording "onions cost twice as much as potatoes" is understood to mean the cost per pound of onions (n) is equal to two times the cost per pound of potatoes (2p). Then the appropriate equation would be ...
2p = n
Then the solution is ...
6p +3(2p) = 18
12p = 18
p = 18/12 = 1.50
n = 2p = 2(1.50) = 3.00
__
The equation should be 2p = n; onions cost $3.00 per pound; potatoes cost $1.50 per pound.
