The word in the problem that indicates is a negative number is “descend”
Answer:
The solution to the given system of equations is (-2,
)
Therefore the values of x and y are x=-2 and ![y=\frac{5}{3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B3%7D)
Step-by-step explanation:
Given equations can be written as
![y=\frac{2}{3}x+3\hfill (1)](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx%2B3%5Chfill%20%281%29)
Solving equation(2) we get
x=-2
Substitute x=-2 in equation (1) we get
![y=\frac{2}{3}(-2)+3](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7D%28-2%29%2B3)
![=-\frac{4}{3}+3](https://tex.z-dn.net/?f=%3D-%5Cfrac%7B4%7D%7B3%7D%2B3)
![=\frac{-4+9}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-4%2B9%7D%7B3%7D)
![=\frac{5}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B3%7D)
Therefore the values of x and y are x=-2 and ![y=\frac{5}{3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B5%7D%7B3%7D)
The solution to the given system of equations is (-2,
)
First put the words in an algebraic format or a model. D = 3.5(√H). Now determine what the question is asking. It's height. Plug in the value of D. Distance is 35 km.
35 = 3.5(√H) We want to get H by itself. First thing to get away from it is 3.5. So divide 35 by 3.5 And 3.5(√h) by 3.5.
10 = √H To get rid of √ do the opposite raise to the power of 2
10² = (√H)²
100 = H
You must be 100 kilometers above ground to see 35 kilometers
