10/2(25-20)
Use distributive property to simplify bottom.
2 x 25 = 50 and 2 x 20 = 40
Now you have 10/50-40
50 - 40 = 10
10/10 = 1
Your answer is 1.
A) We can pick any two values from the table then can subtract initial value from final value divide by the number of instance which will give us the rate of change.
b) Same with the graph, we take two coordinates and then apply in the formula:
slope (m) = y2-y1 / x2-x1
c) We can write the equation, by substituting into the formula:
y - y1 = m (x - x1)
Where y-interecpt & slope is most important
d) When, we completely solve the equation, then it gives y-intercept, and first value of the path in the graph is known as initial value
e) In linear interval, difference between any two instances must be same, 'cause they follow the rule of proportionality whereas in non-interval, differnce will be different in magnitude
Hope this helps!

Answer: 1 + (-1) + (-4) = -4
Step-by-step explanation:
By counting how many chips there are, you can get the following:
1 positive chip + 1 negative chip + 4 negative chips, which is
+1 + -1 + 4 x -1
= 1 -1 -4
= -4
Answer: B.
Step-by-step explanation:
Suppose you have a L.L. Bean coupon of $63.60 and you want to know the final or sale price if the discount is 20 percent.
Using the formula (b) and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 63.60 - 12.72
Sale Price = $50.88 (answer).
This means the cost of the item to you is $50.88.
You will pay $50.88 for a item with original price of $63.60 when discounted 20%.
In this example, if you buy an item at $63.60 with 20% discount, you will pay 63.60 - 12.72 = 50.88 dollars.
