Which ordered pair is the solution to the system of equations? {−3x+4y=−20y=x−4

(−4, −8)

(−2, −6)

(4, 8)

(0, −5)

please answer :)

x = 8/7 and y = 1/7 but I can't find them in the possible answers.

Step-by-step explanation:

-3x+4y = -20y = x-4

from this equation 2 equations can be drawn that is:

-3x+4y = -20y (1)

x-4 = -20y (2)

From eqn(2)

x = -20y + 4

Solving simultaneously:

Substituting the value of x into eqn(1)

-3(-20y + 4) + 4y = -20y

60y - 12 + 4y = -20y

Grouping like terms

64y + 20y = 12

84y = 12

y = 1/7

x = -20(1/7) + 4

x = 8/7

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
