Answer:
x+z=m
Step-by-step explanation:
Answer:
6=-4x+b
Step-by-step explanation:
You plug in the numbers but the formula that you use is y=mx+b with x being the number you don't know
y=3 and x= 5
Step-by-step explanation:
- 3×+×=-1 and 4y-2y=3
- 4×=1 and 2y=3
- ×=4-1 and y=3+2
- x=3 and y=5
Answer: a and d
Step-by-step explanation:
First of all, we need to make a analysis of each letters:
a. factoring 32 = 2.2.2.2.2 = ![2^{5}](https://tex.z-dn.net/?f=2%5E%7B5%7D)
![2^{5}^{3} = 2^{15}](https://tex.z-dn.net/?f=2%5E%7B5%7D%5E%7B3%7D%20%3D%202%5E%7B15%7D)
then,
16 = ![2^{4}](https://tex.z-dn.net/?f=2%5E%7B4%7D)
but ![2^{4}^{4} =2^{16}](https://tex.z-dn.net/?f=2%5E%7B4%7D%5E%7B4%7D%20%3D2%5E%7B16%7D)
in conclusion that, this inequality is correct
b. 27 = ![3^{3}](https://tex.z-dn.net/?f=3%5E%7B3%7D)
this first situation is equal to ![3^{9}](https://tex.z-dn.net/?f=3%5E%7B9%7D)
the second situation is:
81 = ![3^{4}](https://tex.z-dn.net/?f=3%5E%7B4%7D)
and ![3^{4}^{4} = 3^{16}](https://tex.z-dn.net/?f=3%5E%7B4%7D%5E%7B4%7D%20%3D%203%5E%7B16%7D)
it's a mistake.
c. factoring 9: ![9 = 3^{3}](https://tex.z-dn.net/?f=9%20%3D%203%5E%7B3%7D)
< ![3^{5}](https://tex.z-dn.net/?f=3%5E%7B5%7D)
it's wrong.
d. factoring 8 = ![2^{3}](https://tex.z-dn.net/?f=2%5E%7B3%7D)
factoring 32 = ![2^{5}](https://tex.z-dn.net/?f=2%5E%7B5%7D)
> ![2^{10}](https://tex.z-dn.net/?f=2%5E%7B10%7D)
This is true.
Finally.. our correct answers is a and d.
