Answer:
x= 0, -1
Step-by-step explanation:
Answer:
Dividing by 4 and -4
Step-by-step explanation:
Solving 4x < -16 is different from solving -4x< 16, because for 4x < -16, you are dividing by a positive 4 on both sides, but for -4x< 16, you are dividing by -4 on both sides.
Answer:
b. both functions have a negative slope
Step-by-step explanation:
The given function is
![f(x)=-6x-21](https://tex.z-dn.net/?f=f%28x%29%3D-6x-21)
This function is of the form
, where
is the slope and
is the y-intercept.
We can also determine the slope of the function in the table using any two points, say
.
The slope formula is given by,
.
If
, then,
![m=\frac{6-7}{2-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6-7%7D%7B2-0%7D)
.
We can see that both functions have a negative slope.
The correct answer is B.
simplify to 1 hour which will be 6 minutes in 1 hour
in 3 hours it will be 18 minutes
