y=7
Answer:
Step-by-step explanation:
The pressure is equal to the atmospheric pressure 101 kN/m plus 8 kN/m for every meter below the surface, therefore;
a. expression for pressure is given by,
............................... (1)
where d = depth below the surface in meter.
b. to find the depth at any pressure, equation (1) above is rearranged to make depth (d) subject of the formula

as an example, to find depth at pressure of 200N/m
d = (200 - 101)/8 = 12.375 meters
depth is 12.375 meters below the surface.
Answer:
27 =x
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
4x+7 = 5(x-4)
Distribute
4x+7 = 5x-20
Subtract 4x from each side
4x+7-4x = 5x-4x-20
7 = x-20
Add 20 to each side
7+20 = x-20+20
27 =x
Answer:
Step-by-step explanation:
Unfortunately, I don't have access to the "Ray Tool."
The "absolute value function" has a v-shaped graph that opens up and has its vertex at (0,0). Plot a dark dot at (0,0). Starting with your pencil point on this dot, move 1 unit to the right and then 1 unit up. This represents a slope of 1/1, or simply 1. Draw a straight line with slope 1 starting with the black dot at (0,0) and continuing upward and to the right.
Then reflect this line across the y-axis. This 2nd line will have a slope of -1.
I'm including a short table of values that may help you with this graphing:
x y = |x| (x, y)
0 0 (0,0)
1 1 (1,1)
2 2
5 5
-1 1
-3 3 (-3,3)
and so on.
