Answer:
(6, -3)
Step-by-step explanation:
I will solve this system using elimination.
[/tex]
I will multiply by 2 so that -x becomes -2x.
2(-x + 2y = -12)
Distribute.
-2x + 4y = -24
Now subtract this from the other equation.
2x + 3y = 3
<u>-2x + 4y = -24</u>
7y = -21
Divide both sides by 7.
y = -3
Now that we have the value of y, plug it into the original equation.
-x + 2(-3) = -12
Simplify.
-x - 6 = -12
Add 6 to both sides.
-x = -6
Divide both sides by -1.
x = 6
(6, -3)
Answer:
yes
Step-by-step explanation:
they are both triangles
The sales tax is 18 ×
, which is 1.26

Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.
In your case this theorem sounds as
