Answer: (-8, -80)

Step-by-step explanation:

y = 10x

y = -3x - 104

Substitute "y" with "10x" into the second equation, then solve for x:

10x = -3x - 104

13x = -104 added 3x to both sides

x = -8 divided both sides by 13

Next, substitute -8 for x into the first equation to solve for y:

y = 10(-8)

= -80

Step-by-step explanation:

here's your solution

=> in first figure , base = 5.5, perpendicular =7.8

=> h^2 = 5.5^2 + 7.8^2

=> h^2 = 30.25 + 60.84

=>h^2 = 91.09

=> h = √91.09

=> h = 9.5

 Both figure are congruent

enc we will get a rectangle by add both
