She is starting at 4000, so that is the y-intercept of the graph. She is descending at 40 feet per minute, so her rate of change or slope is -40. The graph would look like this:
Answer:
It takes 1 year.
Step-by-step explanation:
You have to apply simple interest formula, I = (P×R×T)/100 where I represent interest amount, P is principle, R is interest rate and T is number of years :
Answer:
2x + 8x
10x
Step-by-step explanation:
Open the brackets and multiply x inside.
One way to solve this is to revert to integers.
Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)
Now you have 1,300,000 & 680000. Subtract to get 620,000.
Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5
We have 6.2 x 10^5.
It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
The linear equation that represent the situation is 3b - 6 = 45.
The value of b is 17.
<h3>How to represent a linear equation?</h3>
The situation forms a linear equation. Therefore,
y = mx + b
where
Therefore, let's model the equation linearly,
where
- b = number of books bought
She bought the book for $3 each and receive a discount of $6. The total money spent after the discount is $45.
Therefore, the equation is as follows
3b - 6 = 45
The value of b is as follows;
3b - 6 = 45
3b = 45 + 6
3b = 51
b = 51 / 3
b = 17
