Log x+ log 7= log 42
log x=log 42 - log 7
log x=log 42/7 [ log a - log b= log (a/b) ]
log x= log 6
therefore:
x=6
Answer: x=6
Step-by-step explanation:
56,000÷7=8000
56,000÷70=800
56,000÷700=80
56,000÷7000=8
13) B. 8.47,8.67,8.7
14) A
Just ask for explanation if u need it
Hope that helped :)
Answer:
y = -(1/3)x + 2
Step-by-step explanation:
Keeping in mind the equation of a line: y = mx + c
Notice three discernible points on the graph: (0,2), (3,1), (6,0).
The first and last points mentioned represent the intercept on y-axis and the intercept on x-axis respectively.
Therefore, when x = 0, y = 2. And 2 = m(0) + c
c = 2
Also, when y = 0, x = 6. And 0 = 6m + 2
6m = -2. And m = -(2/6) = -(1/3)
Therefore, y = -(1/3)x + 2
