Solve for X. -18=9-3x

Mathematics

Answer:

x=9

Step-by-step explanation:

To solve for x, we need to get it by itself. To do this, we need to do the opposite of what is being done to the equation, and anything we do on one side must be done on the other.

-18=9-3x

Subtract 9 from both sides

-18-9=9-9 -3x

-27=-3x

Divide both sides by -3

-27/-3= -3x/-3

9=x

Answer:

9

Step-by-step explanation:

1) Add 9 to both sides:   -18 = 9 - 3x

                                        -9  -9

2) The positive and negative 9 cancel each other out. Leaving you with -27=-3x

3) Divide -3 from both sides (isolate the x!) This will leave you with 9

So.... x = 9

Consider h(x)=x^2+8+15. identify its vertex and y-intercept.
OleMash [197]

Answer:

Vertex: (-4, -1)

Y-intercept: (0, 15)

Step-by-step explanation:

Given the quaratic function, h(x) = x² + 8x + 15:

In order to determine the vertex of the given function, we can use the formula, [x = \frac{-b}{2a}, h(\frac{-b}{2a})].

<h3>Use the equation:  [x = \frac{-b}{2a}, h(\frac{-b}{2a})]</h3>

In the quadratic function, h(x) = x² + 8x + 15, where:

a = 1, b = 8, and c = 15:

Substitute the given values for <em>a</em> and <em>b</em> into the equation to solve for the x-coordinate of the vertex.

x = \frac{-b}{2a}

x = \frac{-8}{2(1)}

x = -4

Subsitute the value of the x-coordinate into the given function to solve for the <u>y-coordinate of the vertex</u>:

h(x) = x² + 8x + 15

h(-4) = (-4)² + 8(-4) + 15

h(-4) = 16 - 32 + 15

h(-4) = -1

Therefore, the vertex of the given function is (-4, -1).

<h3>Solve for the Y-intercept:</h3>

The <u>y-intercept</u> is the point on the graph where it crosse the y-axis. In order to find the y-intercept of the function, set x = 0, and solve for the y-intercept:

h(x) = x² + 8x + 15

h(0) = (0)² + 8(0) + 15

h(0) = 0 + 0 + 15

h(0) = 15

Therefore, the y-intercept of the quadratic function is (0, 15).
