Hi Alyssasmith21!
So $55 for each diamond ring and wants to know how many she needs to sell to get $605. OK this is easy what we have to do is 605/55 to find how many rings which is 11. She needs to sell 11 rings to get $605.
Hope this helps!
Answer:
he was suppost to round up
Step-by-step explanation:
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
22 1/2= 6 3/8+ 3 1/4+ x
22 1/2= 6+3(3/8+1/4)+x
22 1/2= 9 (3/8+2/8) +x
22 1/2= 9 5/8 +x
22 1/2 -9 5/8 =x
22-9(1/2-5/8)=x
13(4/8-5/8)=x
13 (-1/8)=x
12 7/8
