F(-3)=-2(-3)^2-5(-3)+4 <---- Plug in -3
F(-3)=-2(9)+15+4
F(-3)=-18+15+4
F(-3)=7
F(-3)=7
Answer:
x = 2m
Step-by-step explanation:
2m−5−x+19=14
Step 1: Add -2m to both sides.
2m−x+14+−2m=14+−2m
−x+14=−2m+14
Step 2: Add -14 to both sides.
−x+14+−14=−2m+14+−14
−x=−2m
Step 3: Divide both sides by -1.
−x
/−1
=
−2m
/−1
x = 2m
