Anchara used the distributive property and the properties of equality to solve the equation 7 - 3(4 - 2x) = 4(x - 4) + 2x + 11, got the result -5 = -5 at her last step, and became confused. Did Anchara make a mistake in applying the properties? If so, describe the mistake and its significance, and tell how to correct it. If not, explain the algebraic and graphical meaning of Anchara's result.

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 -

believe it or not anna is correct good job anna give me a fist bump there u go gal

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
