cause we know that the base is more than 1 , we can do this way:
![{x}^{2} - 3x < 4](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%203x%20%3C%204)
so we can answer it:
x^2_3x-4<0 x is -1 or -4 to make it 0
so after obtaining the signs of equation we can have:
x=(-4,-1)
Answer:
Concept: Mathematical Modeling
- Range: Highest # - Lowest #
- Median is the middle value in an organized list
- 51-36= 15
- Median: 36,38,39,39,40,47,48,51
![\frac{39 + 40}{2} = 39.5](https://tex.z-dn.net/?f=%20%5Cfrac%7B39%20%2B%2040%7D%7B2%7D%20%20%3D%2039.5)

1. its 23, because if you were to substitute 5 for x, 7(5) = 35 and if you were to substitute -3 for y, 4(-3) = -12. Therefore, 35 + -12 = 23.
Answer:
x = ³/₅
Step-by-step explanation:
1⅔/x = 2⁷/₉ Convert the right-hand side to improper fraction
1⅔/x = ²⁵/₉ Multiply each side by x
1⅔ = ²⁵/₉x Convert the left-hand side to improper fraction
⁵/₃ = ²⁵/₉x Multiply each side by 9
15 = 25x Divide each side by 25
x = ³/₅
<em>Check: </em>
1⅔/⅗ = 2⁷/₉
⁵/₃ × ⁵/₃ = ²⁵/₉
²⁵/₉ = ²⁵/₉
