Answer:
Step-by-step explanation:
4^3 × 4^n = 4^12
Using indices multiplication rule
4^(3+n) = 4^12
4 cancelled out 4
Therefore: 3 + n = 12
n = 12 - 3
n = 9
Answer:
y = -1/4x + 1
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
The y-intercept of the line is 1, so in slope-intercept form, b will be 1.
Now, the line also intersects the y-axis at (4, 0). We can plug these two points into slope formula to find the slope: (0-1)/(4-0) = -1/4.
Therefore, the equation of the line is y=-1/4x + 1
(3x²y²)/(12x)
Divide each number and variable. Note that when you are dividing variables, you are subtracting the powers.
3/12 = 1/4
x²/x = x
Answer: (x(y²))/4

Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
