Answer:
Refexive I think
Step-by-step explanation:
5(3) = 3(5)
or
x(y) = y(x)
I found this
"Anything equals itself: this is the "reflexive" (reflecting onto itself) property. Also, it doesn't matter which order the equality is in; if x = y, then y = x: this is the "symmetric" (they match) property."
9x + 4 = 58
9x = 54
x = 6
The number is 6.
{-2x-5y=13
<u>{2x-5y=17 </u>(+)
<em /> -2x+2x-5y-5y=13+17
-10y=30 /:(-10)
y=-3
2x-5y=17
2x-5*(-3)=17
2x+15=17
2x=2
x=1
<em>Solution: (1; -3)</em>
Answer:
B. x ≥ -3
Step-by-step explanation:
-4 x - 10 ≤ 2
add ten by both sides
-4x≤12
divide -4 by both sides
x ≤ -3
BUT because you divded you have to switch the sign so
x ≥ -3
