Hello,
-2x+2y=8==>y=x+4(1)
The perdicular passing trought (4,-2) is
y+2=-1(x-4)==>y=-x+2(2)
The intersection is
(1)-(2)==>2x+2=0==>x=-1 and y=-1+4=3
Q=(-1,3)
P=(4,-2)
Distance PQ= √(( -1-4)²+(3+2)²)=√50=7,0710678...
Answer:
5 snack bags and 6 juice boxes.
Step-by-step explanation:

Answer:
$100.80
Step-by-step explanation:
84 x 1.2 = 100.8
Evaluate a^2 where a = -5:
a^2 = (-5)^2
Hint: | Evaluate (-5)^2.
(-5)^2 = 25:
Answer: 25
2x + 6 = 4x/2 + 12/2
To solve this, we need to transpose like terms to the same side.
2x - 4x/2 = 12/2 - 6
2x - 2x = 6 - 6
0 = 0
Since both sides are zero, it means that the equation has infinite number of solutions.
