Ok so
log₁₂₅25
remember
logₐy=x means aˣ=y
and
remember that (xⁿ)ᵇ=xⁿᵇ
and
if aⁿ=aᵇ where a=a, then n=b
so
log₁₂₅25=x means
125ˣ=25
to solve, convert to same base
125=5³
25=5²
(5³)ˣ=5² means
5³ˣ=5²
therefor
3x=2
solve
divide both sides by 3
x=2/3
answer is C
8-(-16) would be equivalent to 8+16 which is 24!!!
Answer: the median is 30 and the mean is 26.4
Step-by-step explanation: to find the median you order it from least to greater and find the middle number. For the mean add all numbers and divide from how many numbers are there , so you would divide by 5.
Answer: -4 5/12
Add the negatives first. Then add the positive number to find your answer.
Answer:
To find the slope of the proportional relationship, use the slope formula. The slope formula is Y2-Y1/X2-X1. Plug in any two points into the equation and solve. I will use (8,10) and (12,15).
15-10/12-8
5/4
The slope of the proportional relationship is 5/4.
Hope this helps! :)
