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

sides are 4cm, 8cm, 8cm ----( because isosceles triangle have 2 sides equal )

so, perimeter = sum of all sides

= 4 + 8 + 8

<h3> = 20cm</h3><h2>-------------------------------------</h2><h2>FOLLOW ME</h2>

Answer:

a. Vertex = (2.5,-12.25)

b. y-intercept = (0,-6)

c. x-intercept = (6,0) ; (-1,0)

Step-by-step explanation:

Your equation is written as:

$y = ax^{2} + bx +c$

The easiest way to find the vertex is writing the equation this way:

$y = a(x-h)^{2}+k$

Being the vertex (h,k)

So first complete the square

$y = x^{2} -5x -6 \\y = x^{2} - 2(2.5x) -6 \\y = x^{2} - 2(2.5x) +2.5^{2} - 2.5^{2} -6 \\y = (x^{2} -2(2.5x) + 2.5^{2}) -6.25 - 6 \\y = (x-2.5)^{2} -12.25$

Vertex : (2.5,-12.25)

To find the y-intercept you need to replace the equation when x = 0 and get y

$y = (0)^{2} - 5(0) -6\\y = - 6$

To find the x-intercept you need to replace the equation when y = 0 and get x

$0 = x^{2} - 5x -6 \\0 = (x-6)(x+1)\\x = 6\\x = -1$

Answer:

Value of a in term of x = 8/x

Step-by-step explanation:

Given:

14 = ax + 6

Find:

Value of a in term of x

Computation:

⇒ 14 = ax + 6

Step 1; Subtract 6 from both side

⇒ 14 - 6 = ax + 6 - 6

We get step 2

⇒ 8 = ax

Divide x from both side and we get step 3

⇒ 8 / x = ax / x

Step 4

⇒ 8/x = a

Step 5

⇒ a = 8/x

Value of a in term of x = 8/x
