If a^ x = b then:
x = log_{a}b
For:
4^{7} = 16384 \\ log _{4}16384 = 7
Answer:
b
c
a
d

split into=division
Answer:


Step-by-step explanation:
The given system is
3x-2y=6
0.4(20y+15)=x
The slope intercept form is y=mx+c.
For the first equation, 3x-2y=6, we add -3x to both side -2y=-3x+6

For 0.4(20y+15)=x, we expand to get:


Divide through by 8

Therefore the system in slope-intercept form is:


Answer:
24 books.
Step-by-step explanation:
The number of books that that can be fitted into the shelf is equal to the width of the self divided by the width of each book:

Answer:
3
Step-by-step explanation:
the rate of change of the function, or the slope is 3 because to get to one point from the other point in the line, you would have to go up 3 and over 1 (3/1) or just 3.
Hope this helps
