wariber [46]
To get from 12 smores to 3 smores, you divide by 4. Therefore, you divide the amount of ingredients by 4 also, which is 12 ÷ 4 = 3 and 8 ÷ 4 = 2. So she needs 3 marshmallows and 2 Graham crackers for 3 smores. Hope this helped!

The endpoints of CD are C(1, -6)and D(7,5). Find the coordinate of the midpoint, M
yuradex [85]

Answer:

(4, - 0.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ \frac{x_{1}+x_{2}  }{2} , \frac{y_{1}+y_{2}  }{2} ]

Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then

midpoint = ( \frac{1+7}{2} , \frac{-6+5}{2} ) = \frac{8}{2} , \frac{-1}{2} ) = (4, - 0.5 )

tankabanditka [31]

Answer:

f(g(x))= x-2

Step-by-step explanation:

f(g(x))= (x-4)+2      -plug g(x) into the place of x in the f(x) function

f(g(x))= x-4+2        -parentheses aren't needed

f(g(x))=x-2             -combine like terms
