Answer:
The lengths of the diagonals is 22.
Step-by-step explanation: Since the shape is a rectangle, the diagonals are congruent, we can form the equation 3x+7=5x-3.
Solve for x; 2x=10-->x=5.
Plug 5 into one of the equations. 3(5)+7=22. 5(5)-3=22
Hope this helps!

Answer:
y=1/2x-2
Step-by-step explanation:
perpendicular lines have a neg. reciprocal for the slope.
for example:
in this equation y=-2x+1
-2 is the slope and the negative reciprocal would be 1/2
hence, the slop of our new line is 1/2
y=1/2x+b
we can substitute the coordinates given for x and y:
2=1/2(8)+b
2=4+b
-2=b
hence the new equation is y=1/2x-2
The plane starts at 202 m.
All altitudes are in meters.
After 1 second, it is at 202 - 1.8
After 2 seconds, it is at 202 - 1.8 * 2
After 3 seconds, it is at 202 - 1.8 * 3
etc.
After x seconds, it is at 202 - 1.8 * x
202 - 1.8 * x is the same as 202 - 1.8x
Answer: F. t(x) = 202 - 1.8x
