x =  0.6667
y =  -2
r1 = (Correct answer is: R) Wrong answer
u =  -1
v =  5
r2 = (Correct answer is: K) Wrong answer
q =  -2
w =  -1
r3 = (Correct answer is: K) Wrong answer
m =  2
n =  1

Step-by-step explanation:

y=3x2 k=3>0 r0=R

0 = 3·x-2

3x = 2


x = 2/3 = 0.66666667

x = 2/3 ≈ 0.666667

Our simple equation calculator calculates it.

y = 3·0-2

y = -2


y = -2/1 = -2

y = -2

Our simple equation calculator calculates it.
y=5x+5 k=5>0 r1=R

0 = 5·u+5

5u = -5


u = -5/5 = -1

u = -1

Our simple equation calculator calculates it.

v = 5·0+5

v = 5


v = 5/1 = 5

v = 5

Our simple equation calculator calculates it.
y=0.5x1 k=0.5<0 r2=K

0 = -0.5·q-1

0.5q = -1


q = -1/0.5 = -2

q = -2

Our simple equation calculator calculates it.

w = -0.5·0-1

w = -1


w = -1/1 = -1

w = -1

Our simple equation calculator calculates it.
y=0.5x+1 k=0.5<0 r3=K

0 = -0.5·m+1

0.5m = 1


m = 1/0.5 = 2

m = 2

Our simple equation calculator calculates it.

n = -0.5·0+1

n = 1


n = 1/1 = 1

n = 1

Our simple equation calculator calculates it.
