The correct solution is C

Subtract 6 from both sides of the equation
        3x + 6 - 6 = 21 - 6
        3x = 15

Then divide both sides by 3

       \frac{3x}{3}   =    \frac{15}{3}
       
       x = 5

Natalija [7]

Answer:

A. {−3.5, −2, 1, 2.5}

Step-by-step explanation:

Remember that the range is the possible values for Y in any given function, so in this case, we are given the Y values and we have to solve the function for x:

y=9+6x

6x=y-9

So we just insert the values, the first one being -12.

So since from the options only A has -3.5 as an option that's the correct answer.

hoped this helped! <3

Write the equation in point-slope form of the line that passes through the given points.
Lera25 [3.4K]

Answer:

y-6=-1/3(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(3-6)/(3-(-6))

m=-3/(3+6)

m=-3/9

simplify

m=-1/3

y-6=-1/3(x-(-6))

y-6=-1/3(x+6)

What is the answer to thiss
lana [24]

Hi Student!

This question is fairly simple because it gives us an equation and they also give us a value for the variable that is within the equation and they tell us evaluate the expression.  So let's plug in the values and solve.

<u>Plug in the values</u>

  • m^2 + 5
  • (9)^2 + 5

<u>Factor out the exponent</u>

  • (9*9) + 5
  • 81 + 5

<u>Combine</u>

  • 86

Therefore, the final answer that we would get when substituting m with 9 in the given equation is that we get 86.
