The rule for a rotation by <span><span>90</span></span> about the origin is <span>(x,y)→(−y,x<span>)
A(-2,11) then A(-11,-2)
B(-3,-6) then B(6,-3)
T(10,-4) then T(4,10)

A. the first choice

The answer is y=22 I think
Answer:
First, solve for two points as an equation instead of an inequality to find the boundary line for the inequality.
For:
x
=
0
y
=
0
+
5
y
=
5
Or
(
0
,
5
)
For:
x
=
−
2
y
=
−
2
+
5
y
=
3
Or
(
−
2
,
3
)
We can now plot the two points on the coordinate plane and draw a line through the points to mark the boundary of the inequality.
The boundary line will be solid because the inequality operator contains an "or equal to" clause.
graph{(x^2+(y-5)^2-0.125)((x+2)^2+(y-3)^2-0.125)(y-x-5)=0 [-20, 20, -10, 10]}
Now, we can shade the left side of the line.
graph{(y-x-5) >= 0 [-20, 20, -10, 10]}

In angle A we have supplementary angles, that is
130 + X = 180
X = 180 - 130
X = 50
From the properties of the angles of a triangle - r<em>efer to attached</em>,
W = X + 105
as X = 50 - already calculated above, then
W = 50 + 105
<h3>W = 155</h3><h3 />
Solve<span> A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the </span>equation<span> by 2.</span>
