Answer:
0
Step-by-step explanation:
additive inverse means any number to make the sum zero. in this case 4 +(-4)=0
Answer:
d) f(x) = 5x + 2
Step-by-step explanation:
First we need to identify the variables and how they fit into the equation. in this case we know that the equation is f(x) = mx + b where f(x) is the total cost, m is the hourly cost, x is the number of hours bowled, and b is the price of the shoes.
Now, we need to solve for the hourly cost, so to do this we plug in all the known information to get 12 = m(2) + 2
To solve we need to isolate the variable by first subtracting 2 on both sides to get 10 = m(2) and then dividing both sides by 2 to get 5 = m.
Finally, since we now know that the hourly cost is $5 we can plug this information back into the equation to get f(x) = 5x + 2
perpendicular lies have negative reciprocal slopes
M=5 so m=-1/5
Choice D
Answer:
7 min = 2mi
14min = 4mi
21min = 6mi
28min = 8mi
35min = 10mi
Step-by-step explanation:
Let x be the time, and y be the distance
In this case:
x = 2/7y
You can use this formula to answer all of the sections.
