Create an equivalent system of equations using the sum of the system and the first equation. −5x + 4y = 8 4x + y = 2 −5x + 4y = 8 9x + 5y = 10 −5x + 4y = 8 −x + 5y = 10 −5x + 4y = 8 9x + 5y = 2 −5x + 4y = 8 −x + y = 10

step-by-step explanation: yes

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

pls mark as brainliest

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
