We can model the equation:y = m x + b, where y is the total profit and x is the number of hotdogs sold.The system of equations is:
90 = 40 m + b210 = 80 m + b---------------------b = 90 - 40 m210 = 80 m + 90 - 40 m210 - 90 = 40 m120 = 40 mm = 120 : 40m = 3b = 90 - 40*3b = 90 - 120b = - 30Answer: The equation is y = 3 x - 30
Answer:
<h2>19.25km</h2>
Step-by-step explanation:
Step one:
given data
we are told that the distance that Rahima covers on a daily is 2.75km long
we also know that a week has 7 days that is Mon-Sunday
Required
the total distance for a week
Step two:
Hence the total distance covered for 7 days is
=2.75*7
=19.25km
<em>Simply multiply the distance covered in a day by 7 to get the distance covered in a week </em>
Answer:
(6,0)
Step-by-step explanation:
Answer:
A.-
D.
E.
Step-by-step explanation:
Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is
, the like terms will be those that contain
, regardless of whether their coefficient or sign is different.
Analyzing the options:
A.-
We have the same variable and the same exponent
, so it is a like term.
B. 
You have the same variable x but not the same exponent. So it's not a like term of 
C.
Same variable
but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.
D.
In this option we do have the
, so it is a like term of 
E.
It is also a like term because it contains the
.
In summary the like terms are:
A.-
D.
E.
6-x=5x+30
+x. +x
6=6x+30
-30. -30
-24=6x
X=-4
The answer is -4
