Answer:
y = -5x + 4
Step-by-step explanation:
slope = -5x
y-intercept = 4
y = mx + b --> slope intercept formula
y = -5x + 4 --> final solution
Answer: 54 mph
Step-by-step explanation:
d-the distance
s+9 - the speed to the conference
d=6*(s+9)
s- is the speed on the way back home
d=7*s
so 6*(s+9)=7*s
6s+54=7s
-6s -6s
54= 7s-6s
s=54 mph
First we must apply the Quotient rule that states,
This means that our derivative becomes,
Now we need to calculate 
and 
From here the new equation looks like,
And that is the final result.
Hope this helps.

33 degrees C
Step-by-step explanation:
On the integer scale, the numeric values can be added thus
23 to -10
23 to 0 and 0 to -10
23-0 = 23
0 -(-10) = 10
23 + 10 = 33
Thus, 33 degree C is the difference between the two temperatures.
Answer:
m = 18
Step-by-step explanation:
Step 1: Write out equation
-1/2m = -9
Step 2: Multiply both sides by -2
m = 18
