A triangle is a three-sided polygon. The sum of angles in a triangle is 180 degrees.

Types of triangles

An equilateral triangle : the three sides are equal in length.
An isosceles triangle : two sides are equal in length
A right angled triangle : an angle measures 90 degrees

The perimeter of a triangle is (8t -7 + u) centimeters

The perimeter of a triangle is the sum of the three lengths of the triangle

2t +2 + 6t - 7 + u -2

Combine similar terms

(2t + 6t) + (2 - 7 - 2) + u

Add combined similar terms

8t -7 + u

What is the y-intercept of the quadratic function f(x) = (x – 8)(x + 3)? (8,0) (0,3) (0,–24) (–5,0)

DiKsa [7]

The correct answer is: [C]: " (0, 24) " .
___________________________________________________________

Explanation:
___________________________________________________________

Given the quadratic function:
___________________________________________________________

→ " y = (x − 8) (x + 3) " ; ← Note: Replace the "f(x)" with: "y" ;

→ Find the "y-intercept".
___________________________________________________________

→ Note: The "y-intercept" is the coordinate of the point(s) of the graph of the equation at which the graph crosses the "x-axis" when "x = 0" .

→ So; we set plug in "0" for "x" into our equation; and solve for "y" ;

 → " y = (x − 8) (x + 3) " ;

 → y = (0 − 8) (0 + 3) ;

 → y = (-8) * (3) ;

 → y = - 24 ;
___________________________________________________________

So, the "y -intercept" of the given quadratic function is:

the point at which: "x = 0 ; y = -24 " ;

→ that is; the point the coordinates: " (0, - 24) " ;
___________________________________________________________
→ which is: Answer choice: [C]: " (0, - 24) " .
___________________________________________________________
