Identify a function f" that has the given characteristics. f(–5) = f(4) = 0; f '(-0.5) = 0, f '(x) < 0 for x < -0.5; f '(x) > 0 for x > -0.5 f(x) = How to solve?

i would have to say it is c.

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 -

i suppose it should be (y=2x-5)

step-by-step explanation:

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
