Answer:

x = 11 x = -5

Step-by-step explanation:

(x – 3)^2 = 64

Take the square root of each side

sqrt((x – 3)^2 )=±sqrt( 64)

(x – 3)=±8

Add 3 to each side

x-3+3 = 3±8

x = 3±8

x = 3+8 x = 3-8

x = 11 x = -5

Find the inverse function in slope-intercept form (mx+b):<br> f(x)=-3/5x+6

ruslelena [56]

Answer:

$f^{-1}(x)=-\frac{5}{3} x+10$

Step-by-step explanation:

Steps to find the inverse function:

1) replace f(x) with "y"

$y=-\frac{3}{5} x+6$

2) solve for x:

$y-6=-\frac{3}{5} x\\x=-\frac{5}{3}(y-6)\\ x=\frac{5}{3} (6-y)\\x=-\frac{5}{3} y+10$

3) replace "x" with $f^{-1}(x)$ , and y with x:

$f^{-1}(x)=-\frac{5}{3} x+10$

Norma made quilts and sold them at a craft show. The cost of fabric for each quilt was $13.55. She sold each quilt for $35. The

CaHeK987 [17]

Answer:

least number of quilts is gonna be 10

Step-by-step explanation:

ok...so profit = revenue - expenses

n = # of quilts

revenue : (the money made from the quilts)

she sold each quilt for 35 bucks......35n

expense : (the money Norma spent on the materials)

the cost of fabric is 13.55 per quilt......13.55n

so ur expression is :

revenue - expenses

35n - 13.55n <==== this is part A

==========================

she wants to make a profit of 200...

P = revenue - expenses

200 = 35n - 13.55n

200 = 21.45n

200 / 21.45 = n

9.32 = n.......gonna have to round up to 10 <==== part B

ok...so 9 quilts is not gonna be quite enough...so shes gonna have to make 10.
