Solve the system y = -x + 7 and y = 0.5(x - 3)2
Show all work

x=5, y=2

Step-by-step explanation:

since y = -x+7

substitute it in the second equation to get; -x+7= 0.5(x-3)2

then solve the equation

which would be -x+7= x-3

because 0.5 ×2=1

when you connect the like terms you would get:-x-x=-3-7

which is equals to: -2x=-10

which would make x =5

so just substitute x in equation 1 for 5 which would give

y= -5+7

so y = 2

angle addition postulate

2x=56
