Answer:
A) x=3 or x=6
Step-by-step explanation:
Factor out the GCF : 2(x^2-9x+18)
Then, set to zero.
2(x^2-9x+18)=0
2(x-3)(x-6)=0
x=3 or x=6
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:
Okay I will do this in two orders cause I do not understand if the shirt cost 20 dollars each or all together
Step-by-step explanation:
<u>1</u>. if each shirt cost 20 bucks 2x6=12 add the 0 = $120

Answer:
y = 2x - 5
Step-by-step explanation:
y - 3 = 2 (x - 4)
y = 2x - 8 + 3
y = 2x - 5
