Answer:

(5, -2)

Step-by-step explanation:

Use substitution

Y=5x-27 Put this equation into the place of y in the second one.

2x+3y=4

2x + 3(5x - 27) = 4 then solve for x

2x + 15x - 81 = 4

17x - 81 = 4

17x = 85

x = 5

Then put the value of x back into one of the equations and solve for y

y = 5(5) - 27

y = 25 - 27

y = -2

lukranit [14]

25 in exponential form: $25^{1}$

Factors to make 25 in exponential form: 5 * 5 = 5^2, 1 * 25 = 25^1

Which transformation shows a reflection of ADEF?

antoniya [11.8K]

Answer: B or the second choice

Step-by-step explanation:

well for triangle DEF since E is on the top left, it should be on the bottom right. While F was on the bottom right, it would be on the top left where E originally was. The angles inside has the same situation with E and F, however D stills stays at the top because when reflected like a mirror, D stays at the top. Sorry it’s long and hope this helps!
