Answer:
Unique
Step-by-step explanation:
Let y₁ = 1 - ⁴/₃x (1)
and y₂ = ½(–x + 7) (2)
The slope of Equation (1) is -⁴/₃.
The slope of Equation (2) is -½.
The slopes are different, so there is a unique solution set.
Answer:
The answer is
<h3>2 to 1 significant figure</h3>
Step-by-step explanation:
![1 \frac{2}{5} + \frac{3}{4}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B2%7D%7B5%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B4%7D%20)
To solve the question first convert the mixed fraction to an improper fraction
That's
![1 \frac{2}{5} = \frac{7}{5}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B2%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B7%7D%7B5%7D%20)
So we have
![\frac{7}{5} + \frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B5%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B4%7D%20)
Find the LCM of the fractions
The LCM of 5 and 4 is 20
That's
![\frac{7}{5} + \frac{3}{4} = \frac{7(4) + 3(5)}{20} = \frac{28 + 15}{20}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B5%7D%20%20%2B%20%20%5Cfrac%7B3%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B7%284%29%20%2B%203%285%29%7D%7B20%7D%20%20%3D%20%20%5Cfrac%7B28%20%2B%2015%7D%7B20%7D%20)
![= \frac{43}{20}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B43%7D%7B20%7D%20)
= 2.15
We have the final answer as
<h3>2 to 1 significant figure</h3>
Hope this helps you
Greetings!
Yes, the degree on a monomial can be negative:
Example:
![9x^{-2}](https://tex.z-dn.net/?f=9x%5E%7B-2%7D%20%20)
This is equal to:
![1/9x^{2}](https://tex.z-dn.net/?f=1%2F9x%5E%7B2%7D%20)
Hope this helps.
