Answer:
Step-by-step explanation:
Given question is incomplete; here is the complete question,
Here is an equation that represents a function: 72x + 12y = 60.
Select all the different equations that describe the same function.
A). 120y + 720x = 600
B). y = 5 - 6x
C). 2y + 12x = 10
D). y = 5 + 6x
E).
F). 7x + 2y = 6
G).
Option A.
720x + 120y = 600
72x + 12y = 60
True.
Option B.
y = 5 - 6x
6x + y = 5
12(6x + y) = 12(5)
72x + 12y = 60
True
Option C.
2y = 12x + 10
-12x + 2y = 10
-6(-12x + 2y) = -6(10)
72x - 12y = -60
False
Option D.
y = 5 + 6x
-6x + y = 5
-12(-6x + y) = -12(5)
72x - 12y = -60
False.
Option E.
72x = 60 - 12y
72x + 12y = 60
True.
Option F.
7x + 2y = 6
6(7x + 2y) = 6(6)
42x + 12y = 36
False
Option G
72x = 60 + 12y
72x - 12y = 60
False
Options A, B and E are the correct options.
Answer:
The answer is -6x + 6
Step-by-step explanation:
For us to have an infinite number of solutions, then, what we have on the right hand side will be exactly what we have on the left hand side
Since we have -6x + 6 on the left hand side
To have infinite number of solutions, what we have on the right hand side will be the same
Thus, we have -6x + 6 on the second side
Answer:
$1890.57
Step-by-step explanation:
First we put the 70% on the original 1011, we can do this by multiplying 1011 by 1.7, now we have 1718.7
Now we put on the 10% tax on the new price, we can do this by multiplying 1718.7 by 1.1, now we get 1890.57
Therefore, the final retail price of the mower is $1890.57, respectively
Let's call our unknown angle x .
We know that the sum of the three interior angles of a triangle is 180°
This way,
We get that the third angle measures 29°
