Answer:
343
Step-by-step explanation:
for 3n+2
5+8+11+14+17+20+23+26+29+32+35+38+41+44 = 343
Given :
The four sides of a garden measure 8 1/3 feet, 17 1/4 feet, 17 1/2 feet, and
11 3/4 feet.
To Find :
The length (in ft) of the fence needed to enclose the garden.
Solution :
First simplifying the given mixed numbers :
8 1/3 = 25/3 feet
17 1/4 = 69/4 feet
17 1/2 = 35/2 feet
11 3/4 = 47/4 feet
Now, length of fence needed to enclose the garden is :
Hence, this is the required solution.
Slope = 4/6= 2/3
Intercept is -1 (I think just check with gradient on graph in doing in my head)
Y=MX+B
Y=2/3X-1 ( if my calculations add up
The inverse of this function is f(x) = 2x - 12.
You can find the inverse of any function by switching the f(x) and x values in the equation. Then you can solve for the new f(x) value. The result is your inverse function. The work for this one is below.
f(x) = 1/2x + 6 ----> switch f(x) and x
x = 1/2f(x) + 6 ----> subtract 6
x - 6 = 1/2f(x) ----> multiply by 2
2x - 12 = f(x) ----> change the order for consistency.
f(x) = 2x - 12
6% of her $37,000 in sales: 37,000 x 0.06 = 2220
Salary $1,800 + $2,220 (commission) = $4,020
So her total earnings: $4,020
