<h3>Answer:</h3>
Yes, ΔPʹQʹRʹ is a reflection of ΔPQR over the x-axis
<h3>Explanation:</h3>
The problem statement tells you the transformation is ...
... (x, y) → (x, -y)
Consider the two points (0, 1) and (0, -1). These points are chosen for your consideration because their y-coordinates have opposite signs—just like the points of the transformation above. They are equidistant from the x-axis, one above, and one below. Each is a <em>reflection</em> of the other across the x-axis.
Along with translation and rotation, <em>reflection</em> is a transformation that <em>does not change any distance or angle measures</em>. (That is why these transformations are all called "rigid" transformations: the size and shape of the transformed object do not change.)
An object that has the same length and angle measures before and after transformation <em>is congruent</em> to its transformed self.
So, ... ∆P'Q'R' is a reflection of ∆PQR over the x-axis, and is congruent to ∆PQR.
The estimate that 2.8 million square feet of the building is used for office space is not reasonable
<h3>How to determine the true statement?</h3>
From the plan, the width of the building is:
Width = 230 feet
The building has a circular area, and it has four floors
So, the estimate of the building area is:
Area= 4πR²
So, we have:
Area= 4 * 3.14 * 230²
Evaluate
Area= 664424
The above value cannot be approximated to 2.8 million
Hence, the estimate used for office space is not reasonable

Y=4 (x+ 17/8)^2 - 657/16 hope this helps you out mate =)
Answer:
the answer is the 3 one
Step-by-step explanation:
Answer:
y = (4/7)x + 3
Step-by-step explanation:
rise = 7 - 3 = 4
run = 7 - 0 = 7
slope = rise/run = 4/7
y-intercept = 3
---------------------
Slope intercept form is
y = mx + b
m is the slope = 4/7
b is the y-intercept = 3
the equation is
y = (4/7)x + 3
