A pan has an original price of $32 but is marked down by 15 percent. Which equation shows the new price of the pan?
A. ($32) (100% - 15%) =($32)(85%)=($27.20)
B. ($32) (15%) =$4.80
C. ($32) (15%) +$32=$4.80+$32=$36.80
D. ($32) (185%) =$59.20

The correct equation is A. ($32) (100% - 15%) =($32)(85%)=($27.20)
is (-2, 6) the intersecting point of these two linear equations? x+2y=10 3x+y=0
To determine if (-2, 6) is the intersecting point of these two linear equations, we substitute x = -2 and y = 6 into both equations and check if the equations are satisfied.
For the first equation, x + 2y = 10:
-2 + 2 * 6 = 10
-2 + 12 = 10
10 = 10
The first equation is satisfied.
For the second equation, 3x + y = 0:
3 * (-2) + 6 = 0
-6 + 6 = 0
0 = 0
The second equation is also satisfied.
Since both equations are satisfied by substituting x = -2 and y = 6, (-2, 6) is the intersecting point of these two linear equations.
For the first equation, x + 2y = 10:
-2 + 2 * 6 = 10
-2 + 12 = 10
10 = 10
The first equation is satisfied.
For the second equation, 3x + y = 0:
3 * (-2) + 6 = 0
-6 + 6 = 0
0 = 0
The second equation is also satisfied.
Since both equations are satisfied by substituting x = -2 and y = 6, (-2, 6) is the intersecting point of these two linear equations.
