You could say:
y = 4x + 10
John runs 10 miles a week, after every month he adds 4 miles.
y = 3x + 15
Mary runs 15 miles a week, after every month she adds 3 miles.
'y' would represent the total miles and 'x' would represent the number of months.
Please include the instructions when you post a question. Thanks.
Use the formula A = P*e^(rt).
Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).
As an example: After 2 years you'll have A = $700*e^(0.065*2), or A=$797.18, in your account.
You would need 7 freezer bags because you have to turn both fractions into improper fractions. to get that you have to multiply 15 by 4 and then add 3 so you get 63/1. Then for the next fraction, you multiply 4 by 2 and then add 1 so you get 9/1.
Now you have to divide the 2 fractions to find out how many freezer bags you need. So it would look like this. 63/1 divided by 9/1.
To divide fractions, you use the rule (keep, change, flip)
So you keep the first fraction 63/1 but you change to division sign to multiplication and lastly you flip the second fraction from 9/1 to 1/9 and now you multiply so it looks like this.
63/1 x 1/9 and you get 63/9 which equals 7 freezer bags.
I hope this helped you?? :)
Answer:
Step-by-step explanation:
We know that:
- The initial conditions are -7 meters at 0 minutes.
- Then, after 6 minutes, he was 16 meters below the ground.
According to these two simple facts we can found the linear function that describes this problem. First, the problem says that Mr. Mole is descending at a constant rate, which is the slope of the function. Now, to calculate the slope we need to points, which are and , where <em>t-values </em>are minutes, and <em>y-values </em>are meters. You can see, that the first point is the initial condition and the second point is 6 minutes later.
So, we calculate the slope:
From the slope we can see that Mr. Mole is descending, because it has a negative sign. Also, the point is on the <em>y-axis</em>, because <em>t</em> is null, so -7 is part of the function. Therefore the function that describes this problem is:
I’m pretty sure it would be 1. two less than seven times a number equals thirty-three
