Answer:

x=5

y=4

Step-by-step explanation:

The sides with the 2 bars are equal so

7x-4 = 31

Add 4 to each side

7x-4+4 = 31+4

7x = 35

Divide each side by 7

7x/7 = 35/7

x =5

The sides with 3 bars are equal

4y+8 = 24

Subtract 8 from each side

4y+8-8 = 24-8

4y = 16

Divide by 4

4y/4 = 16/4

y =4

Enter in standard form the equation of the line passing through the given point and having the given slope.. . B(2, - 5), m = -2

dalvyx [7]

Y = mx + b
slope(m) = -2/3
(2,-5)...x = 2 and y = -5
now we sub, we r looking for b, the y int
-5 = -2/3(2) + b
-5 = - 4/3 + b
-5 + 4/3 = b
- 15/3 + 4/3 = b
- 11/3 = b

equation is : y = -2/3x - 11/3...but we need it in standard form
Ax + By = C

y = -2/3x - 11/3
2/3x + y = - 11/3....multiply by 3
2x + 3y = -11 <== standard form

you'll get a decimal format, just multiply it times 100, to get the % format
