For a system of two variables and two equations, each equation will be a linear graph, and where the lines intersect is the solution as an ordered pair (x,y). If the lines don’t intersect (they’re parallel) so there is no unique solution.

A) If 2 points on the rectangle are (a, b) and (c, d), then identify the two missing points on the rectangle?

balu736 [363]

Let us write vertices of the given rectangle are PQRS.

Where Q is (c,d) and S is (a,b).

a) Now, we need to find the coordinates of P and R points.

x-coordinate for P is a and y-coordinate of P is d.

<h3>Therefore P is (a,d).</h3>

On the same way, x-coordinate for R is c and y-coordinate of R is b.

<h3>Therefore R is (d,b).</h3>

b) <em>Width of the rectangle is difference of y-coordinates of P and S points</em>.

<h3>Therefore, width = b - d.</h3>

A radar gun used to determine the speed of passing cars must be within 7 mph of the actual speed of a selected car. If a highway

Marta_Voda [28]

Check that the radar pistol has an error of 7 mph.
Then we have that:
59 mph - 7 mph = 52 mph approximately.
52mph <55mph
Answer:
He does not have irrefutable evidence that the car was speeding in a 55 mph zone
