What are the coordinates of D' after its preimage, D(4, -8), is reflected over the line y = x?

1 answer:

6 0

Answer: D' is (-8,4)

Step-by-step explanation: The rule for reflection y=x is (x,y)>( y,x) So when relecting over the axis y=x the x cordinate and the y cordinate switch places.

Money is borrowed at 14% simple interest. After one year, $1249.44 pays off the loan. How much was originally borrowed? I got $1

WITCHER [35]

The formula is
A=p (1+rt)
A future value 1249.22
P present value ?
R interest rate 0.14
T time 1 year
We need to solve for p
P=A÷(1+rt)
P=1,249.22÷(1+0.14×1)
P=1,095.81 round your answer
P=1096

Is (0,0) a solution to this system? y ≥ x^2 + x - 4, y> x^2 + 2x + 1

Ipatiy [6.2K]

Y≥x²+x-4
y>x²+2x+1

Substitute (0,0):

0≥-4 true
0>1 false

(0,0) is not a solution of the system.
