Answer:
I'd say -1 if its reflecting.... sorry if im wrong mate
Step-by-step explanation:
It is a rhombus
It is so because all its sides are equalto 10cm.
opposite angles are equal. in a parallelogram opposite angles are equal but all sides aren't equal but in case of a rhombus it is so.

The solution to given system of equations is x = 2 and y = -5
<em><u>Solution:</u></em>
<em><u>Given the system of equations are:</u></em>
4x + y = 3 ---------- eqn 1
-2x + 3y = -19 ---------- eqn 2
We have to find the solution to above system of equations
<em><u>We can solve the system by substitution method</u></em>
From eqn 1,
4x + y = 3
Isolate y to one side
y = 3 - 4x ----------- eqn 3
<em><u>Substitute eqn 3 in eqn 2</u></em>
-2x + 3(3 - 4x) = -19
-2x + 9 - 12x = -19
Combine the like terms
-14x = -19 - 9
-14x = -28
Divide both sides of equation by -14
<h3>x = 2</h3>
<em><u>Substitute x = 2 in eqn 3</u></em>
y = 3 - 4(2)
y = 3 - 8
<h3>y = -5</h3>
Thus the solution is x = 2 and y = -5
According to his calculations, b has a 3/10 chance to win
X=10
12x-1=12+10x+7
2x=20
X=10
