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

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
