Remember some simle log rules
loga+logb=log(ab)
xloga=loga^x
means
also, if no base is stated, assume base 10
so
log(2x)=-1 is base 10 and translates to
10^-1=2x
1/10=2x
divide both sides by 2 aka times 1/2
1/20=x
3log(2)+log(x)=3
log(2^3)+log(x)=3
log(8)+log(x)=3
log(8x)=3
base 10
10^3=8x
1000=8x
divide both sides by 8
x=125
Answer:
1. True , it doesn't change the shape
2. False , the x-axis changes
3. False , the angle will change
Answer:
18
Step-by-step explanation:
1/2 of base times height is AREA OF A TRIANGLE
1/2(6*30)=18
Answer:
2x + 40
Step-by-step explanation:
2x+4+x+10-x
= 2x + 40
The minimum of a graph is where the curve of the parabola is at its lowest point. On this graph the minimum looks to be at (-2, -2), but make sure that is where the curve is lowest.
