Find the values of x and y : EK= 7x+5, KG= 3x+17, HK= 3y-11, KF= y+5 NEED ANSWER ASAP

Mice21 [21]

Answer:

Step-by-step explanation:

We know:

The diagonals of the parallelogram are divided in half.

Therefore

EK ≅ KG and HK ≅ KF.

We have

EK = 7x + 5, KG = 3x + 17, HK = 3y - 11 and KF = y + 5

Equations:

(1) 7x + 5 = 3x + 17

(2) 3y - 11 = y + 5

Solutions:

(1)

7x + 5 = 3x + 17 subtract 5 from both sides

7x + 5 - 5 = 3x + 17 - 5

7x = 3x + 12 subtract 3x from both sides

7x - 3x = 3x - 3x + 12

4x = 12 divide both sides by 4

4x/4 = 12/4

x = 3

------------------------------

(2)

3y - 11 = y + 5 add 11 to both sides

3y - 11 + 11 = y + 5 + 11

3y = y + 16 subtract y from both sides

3y - y = y - y + 16

2y = 16 divide both sides by 2

2y/2 = 16/2

y = 8

Find the intercepts and graph the equation x +5y =20

N76 [4]

Answer:

y-intercept: (0, 4)

x-intercept: (20, 0)

Step-by-step explanation:

y-intercept: The y-intercept of a graph is the point where the graph crosses the y -axis. That means, the point in which x = 0.

To find it, we can substitute x by 0 and find y.

x + 5y = 20

0 + 5y = 20

5y = 20

y = 20/5

y = 4

y-intercept: (0, 4)

x-intercept: The x-intercept of a graph is the point where the graph crosses the x-axis. That means the point in which y = 0.

To find it, we can substitute y by 0 and find x.

x + 5y = 20

x + 5*0 = 20

x = 20

x-intercept: (20, 0)

Finally, the graph of the equation is:
