5 0

Answer:

  • Option D

Step-by-step explanation:

<u>Given function:</u>

  • f(x) = 2/3x + 9

<u>Find its inverse:</u>

  • x = 2/3*f⁻¹(x) + 9
  • 2/3*f⁻¹(x) = x - 9
  • f⁻¹(x)  = 3/2(x - 9)
  • f⁻¹(x) = 3/2x - 27/2

Correct choice is D

Answer (4):

a=ub/k because

u=ak/b   (starting equation)

ub=ak    (multiply b to both sides)

a=ub/k   (divide both sides by k)

Answer (6)

x=g+c-y because

g=x-c+y  (starting equation)

x+y=g+c (add c to both sides)

x=g+c-y  (subtract y from both sides)

Ivan has 15 yards of green felt and 12 yards of blue felt to make 3 quilts if Ivan uses the same total number of yards for each
mixas84 [53]

Answer:

9 yards

Step-by-step explanation:

Let the length of each quilt be 'l'.

Given:

Length of green felt (g) = 15 yards

Length of blue felt (b) = 12 yards

Total number of quilts = 3

Now, the length of 3 quilts is given as:

Total\ length=l+l+l=3l ----- (1)

As per question:

Total length = Length of green felt + Length of blue felt

Total length = g+b

Total\ length=15+12=27--------- (2)

Now, comparing equations (1) and (2), we get:

3l=27\\\\l=\frac{27}{3}\\\\l=9\ yards

Hence, each quilt measures 9 yards in length.
