Answer:

7 units

Step-by-step explanation:

Please refer to the image attached with this answer.

Our initial line was CD  joining points (-1,2) and (6,2).

It is now pulled down by 4 units , to new points

(-1,-2) and (6,-2)

Now we again shift this line by 2 units to the left. The new coordinates thus would be C'(-3,-2) and D'(4,-2)

Hence the distance C'D' = 4-(-3) = 4+3 = 7 UNITS

Hence the length of the line will be 7 units.  

It is observed that the length of the line segment remains the same as it was of the original line. as the translation is uniform.

Z varies jointly with x, and y, and z=7 when x= 2, y= 2
fomenos

Answer:

56

Step-by-step explanation:

Complete question:

Z varies jointly with x and y , x=2 and y=2, z=7. Find z when x=4 and y=8 using joint variation . (I need the problem worked out step by step)

If z varies jointly with x, and y, this is expressed as;

z = kxy

If z=7 when x= 2, y= 2

7  = k(2)(2)

7 = 4k

k = 7/4

To get z when x= 4 and y = 8

z = kxy

z =7/4 (4)(8)

z = 7*8

z = 56

Hence the value of z is 56

Find the missing side lengths. Show work. <br> x=______ y=_____
olga_2 [115]
X = 5
Y = 6
Simply we just compare the two shapes and we can see that 6 decreases to 4..so we would assume the rest would decrease by 2. If we were not so sure we could simply do a^2 + b^2 = c^2 and fill in the numbers
