Answer:
yes
no
Step-by-step explanation:
you plug in the 3 into the x, because x=3 so therefore 3+5>7 which becomes 8>7. Is 8 more than 7? yes! so its true. For the next, 7>12, thats not true. And for the last one, 10-7<5, so 3<5, which is true.
It is correct for 5. Incorrect for 6. Lastly, correct for 7.
value
the v stands for value because it just does
3x²-x-2=0
Δ=1+24=25 (Δ=b²-4ac)
x₁,₂=
x1==6/6=1
x2==
so
x1=1
x2=
-24
y=-x+3
rise/run
-1/1
-1
