Answer: <u><em>just a heads up</em></u>
my boats speed is 7 so
x=other boats speed times 2?
Step-by-step explanation:
i am just guessing so please do not take this to seriously
Answer:
its 12 i think because if A D is 5 E B looks about double that so i think its 12
Step-by-step explanation:
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]
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.
<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
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.
