MATH WIZZES, PLEASE HELP ME OUT HERE!! I NEED THIS PROBLEM DONE SOON, BECUASE IT'S DUE IN LIKE 2 MINUTES HELL The equations in this system were added to solve for y. What is the value of y?

x + 6 y = 10. -x + 3 y = -15. = 9 y = -5.

y=-5/9

Step-by-step explanation:

it says 9y=-5

divide both sides by 9

y=-5/9

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
