The vertices of a triangle are P(5, 1), Q(-2, 3), and R(7, -4). What are the coordiantes of the vertices of the image reflected across the x-axis?

sol'n

reflected through x-axis

p(X,y) ) p'(X, -y)

now,

p (5,1) ) p'(5, -1)

Q(-2,3) ) Q'(-2,-3)

R(7,-4)) R'(7,4)

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
