Answer:
C. x+y = 1 and -x-y = -1
Step-by-step explanation:
Remember that if a system of equations has an infinite number of solutions, then the resulting equation from using the first step of the elimination method would have no variables and would be true.
1) Let's try canceling out the equations in option C, x+y =-1 and -x-y =-1. Add the two equations together. (Work shown in attached picture.)
2) All of the terms cancel out with each other, leaving only a true statement of 0 = 0. Thus, option C is the answer.
Answer:
Both graphs have a “y-intercept” at (0,0), so i believe the answer would be they don’t have y intercepts

Answer:
34,879 × 10 = 348,790
Step-by-step explanation:
The answer is <em>348,790</em><em> </em>because 34,879 multipled by 10 is <em>348,790</em><em> </em>as shown in the picture above ^^
Answer:
Field
Field is eroding 4 times faster than the mountain.
Step-by-step explanation:
= The amount of erosion in millimeters
= Number of years passed
The rate at which soil is eroding in the mountain is 0.5 millimeters per year.
The rate at which the field is eroding is 2 millimeters per year.
The field is eroding faster than the mountain.
So the field is eroding 4 times faster than the mountain.
