<h3>1 SongBook costs =$25.85</h3><h3>A guitar costs =$250.10, so 2 Songbooks would cost 2*25.85=51.7.</h3><h3>(2 Songbook) $51.7 * (Guitar) $250.10 = $301.80</h3>
Step-by-step explanation:
A is the correct answer of this question
Answer:
add 12 for all sides I think
Step-by-step explanation:
but if 12 yd is on both sides you must add 12+12 and the after getting the answer add then with 12+12
Answer:
<u><em>(-1,1)</em></u>
Step-by-step explanation:
We can solve this by either graphing and finding ther point the lines intersect, or mathematically, I'll do both.
<u>Graphing:</u>
<u>Mathematically:</u>
−2x + 4y = 6
y = 2x + 3
See the attached graph. The lines intersect at (-1,1)
--------------------
I'll rearrange the first equation (to make it easier for me):
−2x + 4y = 6
4y = 2x + 6
y = (1/2)x + 1.5
Now lets substitute the second equation into the first so that we can eliminate y:
y = 2x + 3
[(1/2)x + 1.5] = 2x + 3
- (3/2)x = (3/2)
x = -1
If x = -1:
y = 2(-1) + 3
y = 1
The solution is x = -1 and y = 1, or (-1,1)
=================
Both approaches give us (-1,1), the solution to the system of equations. It is the only point that satisfies both equations.
