Answer:
m=243/4 when v=9.
Step-by-step explanation:
We know that when y varies directly with x², the formula of direct proportion is
where 'k' is the constant of variation.
so
As m varies directly with v², and m=3 when v=2
m=kv²
k=m/v²
= 3/(2)²
=3/4
Hence, k=3/4
so when v=9 then the expression becomes
m=kv²
substituting v=9 and k=3/4
m= 3/4(9)²
=3/4 × 81
=243/4
Therefore, m=243/4 when v=9.
Answer:
Step-by-step explanation
Let the number be y
y doubled = y×2=2y
2y increases by 3 = 2y+3=
2y +3 is more than 6 but less than 20
2y+3 > 6
2y+3< 20
Solve for y
2y>6-3
y>3/2
2y+3<20
2y<20-3
2y<17
y<17/2

Answer:
3
Step-by-step explanation:
- 3 |2x -3| -5=4
- 3 |2x -3| =4+5
- 2x-3=9÷3
- 2x=3+3
- x=6÷2
- x=3
