Answer:
<h3>y = -1</h3>
Step-by-step explanation:
First let us get the slope of the line PQ and RS
For PQ;
Given P(6, -2) and Q(-2,8)
slope m = 8-(-2)/-2-6
slope of pQ = 10/-8
slope of PQ = -5/4
For RS
R ( − 4 , 3 ) and S(-9, y)
slope of RS = y-3/-9+4
slope of RS = y-3/-5
For PQ to be perpendicular to RS, the product of their slope must be -1
Hence -5/4 (y-3/-5) = -1
y-3/4 = -1
cross multiply
y-3 = -4
y = -4+3
y = -1
Hence the value of y for PQ to be perpendicular to RS is -1
The range of her scores is 17.
<em><u>Explanation</u></em>
Mindy's scores in five tests are:
First, rearranging the data in numerical order, we will get ........
<u>'Range' is the difference between the highest and lowest values</u>.
In the above data set, highest value is 95 and lowest value is 78
So, the range of her scores will be:
So if the area of a square is 320 square meters, then because all four sides are equal, you would end up with the equation
which simplifies to
