-5x + 12 - 7x = -3(5x + 8)

nikitadnepr [17]

Simplify -5x + 12 - 7x to -12x + 12

-12x + 12 = -3(5x + 8)

Expand

-12x + 12 = -15x - 24

Add 15x to both sides

-12x + 12 + 15x = -24

Simplify 12x + 12 + 15x to 3x + 12

3x + 12 = -24

Subtract 12 from both sides

3x = -24 - 12

Simplify -24 - 12 to -36

3x = -36

Divide both sides by 3

x = -36/3

Simplify 36/3 to 12

Lindsay is creating a bridge out of dried pasta and glue. In her plans, she sketches the graph to determine the lengths of the n

alexgriva [62]

From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.

Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
$y=a(x-h)^2+k$

Thus, the equation of the given graph in vertex form is given by
$y=a(x-5)^2+8$

Also, recall that the equation of a parabola with roots, p and q, is given by
$y=a(x-p)(x-q)$

Thus the equation of the given graph can be given by
$y=a(x-1)(x-9)$

To get the value of a, we equate both equations and solve as follows:
$a(x-5)^2+8=a(x-1)(x-9) \\ \\ a(x^2-10x+25)+8=a(x^2-10x+9) \\ \\ ax^2-10ax+25a+8=ax^2-10ax+9a \\ \\ 25a-9a=-8 \\ \\ 16a=-8 \\ \\ a=- \frac{8}{16} =- \frac{1}{2}$

Therefore, the <span>function that Lindsay used to create her design is
$f(x)=-0.5(x-5)^2+8$
