Y=1/2x+3 -x+27=-6 solve using substitution

Nat2105 [25]

Answer:

y= 19.5 x=33

Step-by-step explanation:

-x + 27= -6

(subtract 27 on both sides)

-x= -33

(divide by negative 1 on both sides)

x= 33

(substitute x into the first equation)

y= 1/2x + 3

y= 1/2(33) +3

y= 16.5 +3

y= 19.5

hope this helps :))

Your answer is D. You just take the feet in a mile (5,280) and divide it by his pace (2.75) feet. You get 1920, which is your answer.

Which polynomial correctly combines the like terms and puts the given polynomial in standard form?

Minchanka [31]

Answer: $-5x^3y^3+8x^4y^2-7xy^5+x^2y^4+8x^6$

Step-by-step explanation:

$-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5$

$-5x^3y^3+8x^4y^2+(-xy^5-6xy^5)+(-2x^2y^4+3x^2y^4)+8x^6$

$-5x^3y^3+8x^4y^2+(-7xy^5)+(x^2y^4)+8x^6$

$-5x^3y^3+8x^4y^2-7xy^5+x^2y^4+8x^6$

Y= − 2 ( x − 2 ) ( x + 8 ) −2(x−2)(x+8) in standard form

Harlamova29_29 [7]

Answer:

$y=-4x^{2} -24x+64$

Step-by-step explanation:

$y=-2(x-2)(x+8)-2(x-2)(x+8)$

$y=-2x^{2} +12x+32-2(x-2)(x+8)$

$y=-2x^{2} -12x+32-2x^{2} -12x+32$

$y=-4x^{2} -24x+64$
