Answer:
b = -125/9
Step-by-step explanation:
1 + log5 ( -9b) = 4
Subtract 1 from each side
1 -1+ log5 ( -9b) = 4-1
log5 ( -9b) = 3
Raise each side to the base 5
5^ log5 ( -9b) = 5^3
This will cancel the log5
-9b = 125
Divide each side by 9
-9b/-9 = 125/-9
b = -125/9
The only possible answer is A : -8
all of the rest are positive answers
Answer:
Pink and Green are proportional
Step-by-step explanation:
A proportional graph is a straight line that always goes through the origin
Answer:
The equation of this line would be y = 10x - 8
Step-by-step explanation:
In order to find this we must first see that the parallel line has a slope of 10. Since they are parallel lines, they must have the same slope. So, we can use the slope and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = 10(x - 1)
y - 2 = 10x - 10
y = 10x - 8
So 2^2*2^n=(2^4)^3
2^2= 4
2^4=16
Then 16^3=4096
Now what we have is 4*2^n= 4096
You need to get the 2^n by itself so divide out the 4
4096/4= 1024
2^n=1024
Now you need to do log to get rid of that exponent
Therefore: n=log2(2024) or n=10
ANSWER
n=10
