Answer: 5/2
Step-by-step explanation: Start with the slope formula.
The slope formula can be read as “slope equals the second y-coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate.”
So we have -8 - 2 over -1 - 3 which is -10/-4.
Make sure to write your slope in lowest-terms!
-10/-4 can also be written as 5/2.
Answer:
Choice B is correct
Step-by-step explanation:
We apply the rule of exponents;
![a^{-b}=\frac{1}{a^{b}}](https://tex.z-dn.net/?f=a%5E%7B-b%7D%3D%5Cfrac%7B1%7D%7Ba%5E%7Bb%7D%7D)
![7^{-2}=\frac{1}{7^{2}}=\frac{1}{49}](https://tex.z-dn.net/?f=7%5E%7B-2%7D%3D%5Cfrac%7B1%7D%7B7%5E%7B2%7D%7D%3D%5Cfrac%7B1%7D%7B49%7D)

The table give some information avout the heights (h in cm) of the plants
Step-by-step explanation:
Answer:
infinite amount of solutions.
Step-by-step explanation:
-21=-21-b
-b= -21+21
-b= 0
There is no argument: In real numbers, not only is x/0 undefined for any x, but infinity is not a number, thus it cannot be the result of a division. But there are ways to extend the real numbers (in other words, consider new systems) that do have one or more points at infinity, and some even permit arithmetic to be extended.

Combine like terms. -2y+y=-y. The equation is now -y-3=6. You need to get the y by itself so add 3 to both sides. The equation is now -y=9. You are solving for y so divide both sides by -1. The equation will be y=-9. The answer is y=-9. Hope this helps! ;)
