Answer: Yes, the point (3,4) is a solution to the system.
===================================================
Proof of this:
Replace x with 3 and y with 4 in the first equation
x+y = 7
3+4 = 7
7 = 7
This confirms the first equation. Repeat for the second equation
x-2y = -5
3-2(4) = -5
3 - 8 = -5
-5 = -5
We get true equations for both when we plug in (x,y) = (3,4). This confirms it is a valid solution to the system of equations. It turns out it's the only solution to this system of equations. Visually, the two lines cross at the single location (3,4).

Answer:
1. =
2. <
3. <
Step-by-step explanation:
Note: When comparing decimals you always place both decimals right above each other.
1 is equal to because once you put a 0 behind the 2.1 they are both the same.
2.10
2.1 <add 0 as space holder
2 is less than because they are both negative you are looking for which one is closest to zero.
-4.5 <add 0 as place holder
-4.25 <closest to zero
3 is less than because
(pie) equals 3.141592654 which is less than 3.2.
3.141 <do not need to add whole decimal
3.2 <add two 0's as a placeholder
Answer:
meters
Step-by-step explanation:
From the answer choices, we basically need to find which of them is between
and 
<em>Converting all of them to decimals would make it really easier:</em>
<em />
<em>So we need to find number between -0.5 and -1.67</em>
<em />
<em>Answer choice A is -2.33</em>
<em>Answer choice B is -0.75</em>
<em>Answer choice C is -0.25</em>
<em>Answer chioce D is -1.83</em>
<em />
<em>So which number, from the choices, is between -0.5 & -1.67?</em>
Clearly, it is -0.75, or,
meters
Answer:
B is the answer because a function is if none of the x values are the same with different y values.
