Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
<h3>Slope of a function</h3>
Slope of a function is defined as the rate of change of a function. It determine the unit price of values or amount traveled in unit time.
The formula for expressing the slope of a function is given as;
f'(x) = f(b)-f(a)/b-a
a and b are the intervals
The slope can also be expressed as a function of its coordinate (x, y)
Slope = y2-y1/x2-x1

Answer: he collected 22 quarters and 8 fifty-cent pieces
Step-by-step explanation:
Given;
The total amount of money he is to collect is;
A = 20 - 10.50 = $9.50
Let x represent the number of quarter he collected.
Then the number of fifty-cent pieces he collected will be; 30-x
Therefore we can represent it with the equation below;
0.25x + 0.50(30-x) = 9.50
0.25x + 15 - 0.50x = 9.50
0.25x = 15-9.50
x = (15-9.50)/0.25
x = 5.50/0.25
x = 22
The number of fifty-cent is equal to;
30-x = 30-22 = 8
Therefore, he collected 22 quarters and 8 fifty-cent pieces
Answer:
2.5 cups in each jar
Step-by-step explanation:
10/4 is 2.5
Answer:
Step-by-step explanation:
So you know that m= 
. To find that you need to take one y(6) coordinate and subtract the other y(-2) coordinate. So then you put that in the nominator. Then you take the x(2) coordinate from the same pair that you started with the y(6) coordinate and subtract the other x(0). You put that answer in the denominator. That's how you find slope=m. Then you plug slope in the equation.
y = 
x + b
Then you take on y coordinate and plug it into y.
6 = 4 x + b
Then you insert the x coordinate from the same pair that you did y.
6 = 4(2) + b
Now 4 times 2 is 8 and 8 is not equal to 6. So b must be -2.
You can check it with the other coordinates, and that's how you check your original answer.
