Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's solve your system by elimination.
x−3y=9;−x+3y=−9
x−3y=9
−x+3y=−9
Add these equations to eliminate x:
0=0
<u>Answer:</u>
Infinitely many solutions.
I think But I'm not 100% sure yet it's a guess
Y=3+x
Root: (-3, 0)
Intercept:(0, 3)
Answer:
Yes
Step-by-step explanation:
An integer is a whole number so if x is positive and y is negative then the equation would just be x plus negative y. But x+-y is an odd equation so the simplified version is x-y so it is a rational number, since a rational number is a number that can be rewritten as a simple fraction.
4 and 8 would be the anwser because 4 x 2 = 8 and then 8x1=8
(a) y = -7/5x + 17.8
(b) it decreased by 7/5 per day.
Hope this helps!!! :)
