6 0

Answer:

<h2>             A</h2>

Step-by-step explanation:

Because:

             y(-2)=\frac43\cdot(-2)-\frac13=-\frac83-\frac13=-\frac93=-3

and        y(4)=\frac43\cdot4-\frac13=\frac{16}3-\frac13=\frac{15}3=5

Which equation represents a line which is perpendicular to the line 5x + 2y = 12?
o-na [289]

Answer:

<h2>          y = ²/₅ x - 3</h2>

Step-by-step explanation:

Changing to slope-intercept form:

5x + 2y = 12         {subtract 5x from both sides}

2y = -5x + 12         {divide both sides by 2}

y = -⁵/₂ x + 6

y=m₁x+b₁   ⊥   y=m₂x+b₂   ⇔    m₁×m₂ = -1

{Two lines are perpendicular if the product of theirs slopes is equal -1}

y =-⁵/₂ x + 1    ⇒     m₁ =  -⁵/₂

-⁵/₂× m₂ = -1      ⇒   m₂ = ²/₅

So, any line perpendicular to 5x + 2y = 12 must have slope m =²/₅

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
larisa86 [58]

Answer: (C) divide by 1

<u>Step-by-step explanation:</u>

when dividing by x - 1, set the expression equal to zero to find the zero.  That is actually what you are dividing by:

x - 1 = 0   ⇒   x = 1

so the number outside of the synthetic division symbol is 1.
