Answer:
y = -4x - 3
Step-by-step explanation:
It is given outright that slope is -4, so right now we have:
y = -4x
Now, plug that point's values into the current formula.
-7 = -4(1) + b
-7 = -4 + b
Add 4 to both sides to get b by itself.
-3 = b
Put -3 at the end.
y = -4x - 3
Answer:
it is C.
Step-by-step explanation:
it is C.
To solve this, make the equation:
2l+2(l-4)=72
4l=80
The length is 20 meters.
Then, plug 20 in the other equation:
w=l-4
The width is 16 meters.
Monthly, because your value goes up every month.
