Answer:
120
Step-by-step explanation:
Let g = number of girls.
(2/3)g is 2/3 the number of girls
(2/3)g + 35 is 35 more than 2/3 the number of girls. This is the number of boys.
(2/3)g + 35 = 115
(2/3)g = 80
(3/2)(2/3)g = 80(3/2)
g = 120

you would have 9.375 pieces or 75/8 pieces, depends on how you look at it
Answer:
The domain is (0,5) In the given pair...
Answer:
- f¯¹(x) =9x+18, for the pictorial(image) question
- what is the send question is it asking derivative or inverse
- If it is inverse f¯¹(x)=-x-2 as it is
- Or if it is derivative f'(x)=-1
Step-by-step explanation:
<h2>
For the image question f(x)=1/9x-2,f¯¹(x)=?</h2>
- f(x)=1/9x-2............given
- y=1/9x-2................swapping f(x) by y to Easily write
- x=1/9y-2................interchanging x and y
- 1/9y-2=x................changeling side of equation
- 9(1/9y-2)=(x)9.......multiplying both sides by 9 to override the fraction on the right side
- y-18=9x
- y=9x-18.................Return to where it were
- <em><u>f¯¹(x)=9x+18</u></em>..........swap back f¯¹(x) in the y
<h2>
For the question f(x)=-x-2,f¯¹(x)=?</h2>
- following the ☝️ arrangement
- y=-x-2
- x=-y-2
- -y-2=x
- -y=x+2
- y=-x-2
- f¯¹(x)=-x-2
