Type the equation for the following patterns

Y = 1/2 x

Step-by-step explanation:

y=1/2(x) +c

substitute in x and y to find c:

1/2 = 1/2(1) + c

1/2 = 1/2 + c

0 = c

therefore:

y = 1/2 x

hope this helps!

answer: its the third option.

step-by-step explanation:

i just took the test.

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
