The vertex of a parabola is the point where the parabola crosses its axis of symmetry. Therefore, the coordinates of the vertex is (2,4).
Step-by-step explanation:
3x+12=45
3x=45-12
3x=33
3x/3=33/3
x=11
Answer:
x=-1/4
Step-by-step explanation:
2/5+3/5x=x+5/10
subtract 2/5 form both sides
3/5x=x+1/10
subtract x form both sides
-2/5x=1/10
Multiply both sides by 5
-2x=1/2
x= - 1/4
