Answer: 24xy
I'm not sure if I'm right, but if I am and you have any questions about how it was solved, feel free to ask!! :)
Set it up as a fraction:
8kg = 10kg
24N ?N
cross multiply
8x=240
x=30N
<span>the discriminant formula is D = b^2 - 4ac
(idk how to put graphs or anything but yeh)

Don’t worry! I am happy to help you! Standard form is just the number alone. In this case, here are the numbers written out for you.
1. 53
2. 9,400
3. 707,000
4. 0.0026
5. 0.08651
6. 0.0000067
The next part here is scientific notation. The first number has to be greater than 1, but less than ten, and the number you multiply by is powers of 10, sometime positively and sometimes negatively. You can search up the powers of 10 chart to find more. Here they are written in scientific notation.
7. 5.61 * 10^3
8. 1.4 * 10^1
9. 5.64 * 10^7
10. 7.52 * 10^-1
11. 6.4 * 10^-3
12. 5.81 * 10^-4
For this next part, you have to get these answers and express it in scientific notation. Here are these answers with the work.
13. 69,000,000 + 212,000 = 69,212,000.
Scientific notation: 6.9212 * 10^7
14. 43,000 + 521,000 = 564,000
Scientific notation: 5.64 * 10^5
Answer:
(0,12)
Step-by-step explanation:
As you can see from the chart, when x increases by 10, y increases by 20. We can assume that because of this porportional relationship, when x increases by 1, y will increase by 2. We're looking for the y-intercept, in other words we need to get x to 0. So if we subtract x by 16, we must take 32 away from 44(the y-value), because of this porportional relationship. That gets us an x value of 0, and a y value of 12. (0,12) would be the y-intercept.
