What are the key features of a quadratic graph (or a parabola)? - What is a GCF
- y= -(x+3) -5. Where is the turning point? Is this a max or min
- What is the average rate of change?
- What is general form? what does h, k represent?

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the answer is ! ?

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 -
