The cost equation has a constant rate of change, so this is a line of the form:
y=mx+b, you are told that there is a flat fee of $5 and an hourly rate of $2 so
y=2x+5
The y-intercept (the value of y when x=0) is 5. The point (0,5) on the line.
8.2 is 10% of 82
As 8.2 * 10 is 82.
Answer:
First we must learn to dissect a question.
<h3>Explanation:</h3>
Part 1
We can list our facts first:
- Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
- She needs 13 dozen cookies
She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons
<h3>Part 2</h3>
She needs 9.75 teaspoons and 3 teaspoons make a tablespoon
So..
The goal is to solve for y. Start by subtracting 2x from both sides. This gives you 8y=-2x+16. Now just divide both sides by 8, which gives you y=-2/8x+16/8. Finally, simplify this to y=-1/4x+2.
