Recall the logarithm rules :
a^y = x is the same as log_a x = y
In this case,
a = 18
y = r - 10
x = 93
So,
18^ (r-10) = 93
is the same as
log_18 93 = r - 10
Solve for r to get :
10 + log_18 93 = r
Answer:8.6
Step-by-step explanation:
If you would like to know how much money does Bill earn per week, you can calculate this using the following steps:
$12 per hour
40 hours per week
$12 * 40 hours = 12 * 40 = $480 per week
The correct result would be $480 per week.
Answer:
d. y= 5x+18
Step-by-step explanation:
y=mx+b is slope intercept form
Now we plug in the information given to us which is slope(m) is 5 and a point (x,y) which is (2,28).
So by substituting we get 28=5(2)+b
simplify to 28=10+b and when we subtract 10 from both sides to isolate 'b', we get that b = 18.
So now we use the values of slope(m) and the y-intercept(b) to write the equation:
y=5x+18
Answer:
6
Step-by-step explanation:
216 raised to the one third power is the same as asking for the cubed root of 216. 6x6x6=216
hope this helps :)
