Answer: x = -8, y = 13
Step-by-step explanation:
x+y=5
3x+y=-11
now subtract the two equations
x-3x+y-y=5-(-11)
-2x=16, x = -8
now substitute
-8 + y = 5, y = 13
Answer: I think its all real numbers
Step-by-step explanation:
I can help you only with #2.
Area= l*w
Area=(l+3)*w
Area= 130
Let's try 10 and 13.
Is the length 3 greater than its width? YES
Does it multiply to 130? YES
LENGTH= 13 CM
WIDTH=10 CM
cHECK=
13*10=130
Answer:
- 1/3
Step-by-step explanation:
First you find the slope of the line.
2-(-4) 6
——— = — = 3
2-0 2
To find the slope of the line that is perpendicular to that line, you take the opposite reciprocal of the slope.
-1/3
