Answer:
y = 9x cents
y = (36 + 3x) cents
Step-by-step explanation:
Given that:
Newtown telephone company :
Fee per minute = 9c
Tyrus company :
Fee per minute = 3c
Connection fee = 36c
Cost equation :
y = total cost for each phone call:
x = minutes phone call last ;
Newton Company :
y = (fee per minute * minute phone call last)
y = 9 * x
y = 9x cents
Tyrus Company:
y = (connection fee + (fee per minute * minute phone call last))
y = (36 + (3 * x))
y = (36 + 3x) cents
Answer:
x < -6
Step-by-step explanation:
-4x - 5 > 19
+5 +5
-------------------
-4x > 24
/-4 /-4
-------------------
x < -6
The answer is:
(Option 1).
(Option 4).
(Option 5).
The explanation for this answer is shown below:
1. The commutative property of addtion establishes that if you change the order of the addends, the sum will not change.
2. Let's say that 
and 
are real numbers, Then they can added them to obtain a result 
:
3. If you change the order, you will obtain the same result:
4. Therefore, the only options that show the applicaction of this property, are the options shown above.
Answer:
y=1/2x+4
Step-by-step explanation:
a perpandicular line can be made by just making the x negative, or , since it's already negtive, positive.
so i'll start with
y=1/2x+k (just basic equation w no values)
6=2+k (adding values of the coordinate)
4=k (simplifying)
y=1/2x+4 (plugging k back in to the equation)
Note that the length of EACH SIDE of a cube is the same.
1) Volume = s³ ; or; V = s³ .
in which; V = volume (in "cubic units");
s = the side length of any one of the sides of the cube.
_______________________________________________________
2) Volume = length * width * height ; or, ( "V = L * w * h) .
