Answer:
The distance is
or
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
Answer:
36, 6, 49, 7, 6, 7
Step-by-step explanation:
Just like the last one! The key is to think about the perfect squares closest to the number being asked about. For 47, these are 36 and 49, which have square roots of 6 and 7 respectively, so you know it must be between 6 and 7.
Move all y terms to both sides
subtract both sides by 3xy
<span>y=3xy-1
y - 3xy = -1
factor out y from the left side: y(1 - 3x) = -1
divide both sides by (1-3x)
y = -1/(1-3x)

Answer: 32
Step-by-step explanation:
4 cubed 2 divided by 4
Simply is
4 to the power 3 multiplied by 2 divided by 4
4*4*4*2/4
128/4= 32
