Answer:
The solution to the system would be (3, -1)
Step-by-step explanation:
You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.
-5x + 20y = -35
5x + 9y = 6
-----------------
29y = -29
y = -1
Now that we have the value of y, we can plug it into either equation and find the x value.
x - 4y = 7
x - 4(-1) = 7
x + 4 = 7
x = 3
Answer:
Cubic polynomial.
Step-by-step explanation:
Polynomials with their highest degree 3, are called cubic polynomials.
Answer:
none
Step-by-step explanation:
you cant multiply or divide to make them equivalent
Answer:
- Fill the 3-cup container and pour the contents into the 5-cup container.
-This leaves room for 2 cups in the 5-cup container.
- Fill the 3-cup container again and pour the contents in the 5-cup container.
-This now fills the 5-cup container with 2 more cups.
- This leaves one cup left in the 3-cup container
X - $5 bills
y - $10 bills
x + y = 12
y = 5x
x + (5x) = 12
6x = 12
x = 2
y = 5(2)
y = 10
10 $10 bills and 2 $5 bills
