Answer:
oh lord...ill try my best
Step-by-step explanation:
Let's start b writing down coordinates of all points:
A(0,0,0)
B(0,5,0)
C(3,5,0)
D(3,0,0)
E(3,0,4)
F(0,0,4)
G(0,5,4)
H(3,5,4)
a.) When we reflect over xz plane x and z coordinates stay same, y coordinate changes to same numerical value but opposite sign. Moving front-back is moving over x-axis, moving left-right is moving over y-axis, moving up-down is moving over z-axis.
A(0,0,0)
Reflecting
A(0,0,0)
B(0,5,0)
Reflecting
B(0,-5,0)
C(3,5,0)
Reflecting
C(3,-5,0)
D(3,0,0)
Reflecting
D(3,0,0)
b.)
A(0,0,0)
Moving
A(-2,-3,1)
B(0,-5,0)
Moving
B(-2,-8,1)
C(3,-5,0)
Moving
C(1,-8,1)
D(3,0,0)
Moving
im sorry think this is wrong I TRIED MY BESTTTT!!!!!!!! give me credit this is tiring
Answer:
Step-by-step explanation:
To find the exact solution, find the equation for each line. And solve for x and y.
To do this, represent each equation in the slope-intercept form, y = mx + b. Where m is the slope, and b is the y-intercept.
✍️Equation 1 for the line that slopes upwards from left to your right:
Slope = 
b = the point at which the y-axis is intercepted by the line = 7
Substitute m = 2 and b = 7 in y = mx + b
Equation 1 would be:
✔️y = 2x + 7
✍️Equation 2 for the line that slopes downwards from left to your right:
Slope = 
b = the point at which the y-axis is intercepted by the line = 1
Substitute m = -3 and b = 1 in y = mx + b
✔️Equation 2 would be:
y = -3x + 1
✍️Solve for x and y:
✔️To solve for x, substitute y = -3x + 1 in equation 1.
y = 2x + 7
-3x + 1 = 2x + 7
Collect like terms
-3x - 2x = 7 - 1
-5x = 6
Divide both sides by -5
✔️To solve for y, substitute x = -1⅕ in equation 2.
y = -3x + 1
✅The exact solution would be:
Answer: 15 hours and 37 minutes
Step-by-step explanation: 6 and 1/2 hours is 6 hours and 30 mins
8 and 2/3 hours is 8 hours and 67 mins
So 8 hours + 6 hours is 14 hours
Since 67 minutes is over an hour, we're going to take 60 minutes from 67, leaving u with 7 minutes
Add the 60 minutes to the 14 hours and you get 15 hours.
Take the 7 minutes and add it to the 30 minutes and you get 37 minutes.
All together the answer is 15 hours and 37 minutes
