I am pretty sure you would have to divide 350 /  20 to get 17.5.

It takes 17.5 Minutes the get the oven to reach 350 Degrees F

You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f represents number of cookies,c that ca
kompoz [17]

You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f

c represents the number of cookies

f represents the cups of flour

You have 8 cups of  flour, we can use only 0 to 8 cups of flour.

so domain f is 0 to 8 cups [0,8]

Now we find the range

1 cup of flour to make 24 cookies

So 8 cups of flour = 24* 8 = 192 cookies

using 8 cups you can make 192 cookies

So number of cookies is from 0 to 192

Range is [0,192]

At a concession stand, One person purchased 3 drinks and 3 soft pretzels. Another person purchased a total of $9.00. Another per
qaws [65]
X=price of one drink.
y=price of one soft pretzel

We can suggest this system or equations:

3x+3y=9
4x+2y=8.5

We can solve this system of equations by substitution method.
3x+3y=9
3x=9-3y
x=9/3 - 3/3 y
x=3-y

4(3-y)+2y=8.5
12-4y+2y=8.5
-4y+2y=8.5-12
-2y=-3.5
y=-3.5/-2
y=1.75

x=3-y
x=3-1.75
x=1.25

Answer: The price of one soft pretzel is $1.75.

What is the solution to the equation ^3sqrt m-4- ^3sqrt 2m+8=0
fredd [130]
<span>The correct answer is:  [B]:  " m = -12 " .  
________________________________________________________

Explanation:
_________________________________________________________
Given the equation:

</span>→   <span>"  ³√(m − 4)  −  ³√(2m + 8)  =  0  " ;   Solve for "m" ; 

_________________________________________________________

We start by rewriting the terms in the equation:
_________________________________________________________
Note the following property of exponents:
_________________________________________________________
 
       </span>→ "  a ⁽ ˣ / ʸ⁾  =  ʸ√(aˣ)   ;  { y \neq 0 } "  ; 
_________________________________________________________

So, rewrite:   "     ³√(m − 4) " ;  as:  "  (m − 4) ⁽ ¹/³⁾ "  ; 

and rewrite:  "    ³√(2m + 8) " ; as:  " (2m + 8) ⁽ ¹/³⁾ " ;
_________________________________________________________ 
And rewrite the question as:
_________________________________________________________

 
→    "  (m − 4) ⁽ ¹/³⁾     −     (2m + 8) ⁽ ¹/³⁾   =   0 "  ;   Solve for "m" ; 
<span>_________________________________________________________

</span>Add  " (2m + 8) ¹/³ "  to EACH SIDE of the equation; as follows:
_________________________________________________________

       →   (m − 4) ¹/³⁾  −  (2m + 8)¹/³  +  (2m + 8) ¹/³  =  0 + (2m + 8) ¹/³  ;

to get: 
_________________________________________________________

    →   "  (m − 4) ¹/³   =   (2m + 8) ¹/³ "   ;  
_________________________________________________________

 →  { <u>Note</u>:  If   " x ⁿ  =   y ⁿ    ;   then  " x  =  y " .} . 
_________________________________________________________     As such:

    →   "  m  −  4   =  2m  +  8 " ;  Solve for "m" ; 
_________________________________________________________

Subtract "2m" from each side of the equation; & add "4" to each side of the equation; as follows:
_________________________________________________________

              m  −  4  −  2m  +  4   =  2m  +  8  −  2m  +  4  ;

to get:
_________________________________________________________

     
→   -1m   =  12 ; 

Now, divide each side of the equation by "-1 " ;
     to isolation "m" on one side of the equation; & to solve for "m" ; 

    
→    -1m / -1  = 12 / -1 ; 
_________________________________________________________
 
to get:
_________________________________________________________

" m = -12 " ;  

→  which is:  Answer choice:  [B]:  " m = -12 " .
_________________________________________________________
Hope this helps!
       Best wishes.
