Examine the system of equations. y = 3 2 x − 6, y = −9 2 x + 21 Use substitution to solve the system of equations. What is the v
nadezda [96]

Answer:

<h2>y = -4/9</h2>

Step-by-step explanation:

Given the system of equations y = 3/2 x − 6, y = −9/2 x + 21, since both expressions are functions of y, we will equate both of them to find the variable x;

3/2 x − 6 = −9/2 x + 21,

Cross multiplying;

3(2x+21) = -9(2x-6)

6x+63 = -18x+54

collecting the like terms;

6x+18x = 54-63

24x = -9

x = -9/24

x = -3/8

To get the value of y, we will substitute x = -3/8 into any of the given equation. Using the first equation;

y = 3/2x-6

y = 3/{2(-3/8)-6}

y = 3/{(-3/4-6)}

y = 3/{(-3-24)/4}

y = 3/(-27/4)

y = 3 * -4/27

y = -4/9

Hence, the value of y is -4/9

I need help with this problem right away please.
irga5000 [103]

Answer:

y= -1/9(x-1)^2 +2

Step-by-step explanation:

The vertex is at (1,2) and another point is at (-2,1).

We know the vertex form of a parabola is

y= a(x-h)^2 +k  where (h,k) is the vertex  

Substituting the vertex in

y= a(x-1)^2 +2

We have another point, (-2,1)

Substitue this in with x=-2 and y =1.  This will let us find a

1 =  a(-2-1)^2 +2

1 = a (-3)^2 +2

1 = a*9 +2


Subtract 2 from each side

1-2 = 9a +2-2

-1 = 9a

Divide by 9

-1/9 = 9a/9

-1/9 =a

Putting this back into the equation


y= -1/9(x-1)^2 +2

Select the correct answer.
Sophie [7]

Answer:

D)  x² -x - 10  =0

Step-by-step explanation:

Given that

             \frac{2}{3x-6} - \frac{1}{3x+6} = \frac{1}{3}

L.C.M

         \frac{2(3x+6)-(3x-6)}{(3x+6)(3x-6)} = \frac{1}{3}

        \frac{(6x+12-3x+6)}{(3x+6)(3x-6)} = \frac{1}{3}

          \frac{(3x+18)}{((3x)^{2} )-(6)^{2} } = \frac{1}{3}

    ⇒ 3(3x+18) = 9 x^{2} - 36

   ⇒ 9 x + 54 = 9 x² - 36

  ⇒ 9 x² - 36 - 9x - 54 =0

⇒ 9 x²  - 9x - 90 =0

⇒ 9(x² -x - 10 ) =0

⇒ x² -x - 10  =0

Use the graph of f(x) = x2<br> to write an equation for the function represented by each graph.
MariettaO [177]

Answer:

y = -(x + 2)² + 1

Step-by-step explanation:

Parent function given in the graph is a quadratic function,

f(x) = x²

Since, graph is opening downwards transformed function of the preimage will be,

g(x) = -x²

This transformed function is shifted further by 2 units left horizontally and 1 unit upwards.

Therefore, rule for the transformation will be,

g(x) → h[(x + 2), (y + 1)]

By this rule transformed function will be,

h(x) = -(x + 2)²+ 1

Equation of the curve will be,

y = -(x + 2)² + 1
