Answer:1.08
Step-by-step explanation:just multiply it together
240=2*2*2*2*3*5
1500=2*2*3*5*5*5
1. Answer: 15.7143
log (7x-10)=2
Use the identity: loga(x)=b = x=(a)(b)
7x-10=10^2
Evaluate the Power
7x-10=100
Addition Property of Equality
7x=110
Division Property of Equality
x=110/7 or 15.7143
2. Answer: 0.3107
log(3)+log(x^-3)=2
log(3x^-3)=2
log(3 x 1/x^3)=2
log(3/x^3)=2
3/x^3=10^2
3/x^3=100
3=100x^3
3/100=x^3
Answer Cube root 30 / 10 or 0.3107
3. Answer: 0.002
log(5) + log(x) = -2
log(5x)= -2
5x= 10^-2
5x=1/10^2
5x=1/100
x=1/500
Answer: 0.002
Honestly I could tell you the steps, but I do not have a lot of time. Sorry. I will comment later if you need the steps
Answer:
<u>They are parallel.</u>
Step-by-step explanation:
L1: x − y = 2 ; or x-y-2=0
L2: y = x + 1; or x-y+1=0
<em>The slope of the line L: ax+by+c=0 is m= -a/b.</em>
L1: x-y-2=0=><em> m1=(-1)/(-1)=1</em>
L2: x-y-1=0=> <em>m2=(-1)/(-1)=1</em>
L1 and L2 have the same slope; m1=m2=1
=> L1 and L2 are parallel.
