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.
1) Distribute
4 (v+5) -7v
4v + 20 - 7v
2) Combine 4v and -7v
-3v + 20
Therefore, the answer is -3v + 20
24*10 exponent 4 because 240,000 has 4 zeors you take the base and leave it as it is and you count the zeros and turn them into exponent
