HELP!!! I NEED TO FINISH THIS BY THE END OF CLASS!!! what is (5/2, -7/2) reflected across the y-axis?

-Dominant- [34]

The point (x=5/2, y=-7/2) reflected over the y-axis it means that you just drag the point on the other side of y-axis so y is the same and x is negative.

( x= -5/2, y=-7/2) your reflected point is ( -5/2 , -7/2)

QR is tangent to circle P at point Q. Circle P is shown. Line segment P Q is a radius. Line segment Q R is a tangent that inters

Ainat [17]

Answer:

The approximate length of RP is 6.1 units

Step-by-step explanation:

we know that

If Line segment Q R is a tangent to circle P at point Q

then

Line segment QR is perpendicular to line segment PQ (radius) and PQR is a right triangle

Applying the Pythagorean Theorem

$RP^2=PQ^2+QR^2$

substitute the given values

$RP^2=3^2+5.3^2$

$RP^2=37.09$

$RP=6.1\ units$

Answer:

(3 , 2.5)

Step-by-step explanation:

.5x + y = 4

y = .5x+1

.5x + (.5x + 1) = 4

x + 1 = 4

x = 3

y = .5(3)+1

y = 1.5 + 1

y = 2.5
