Y - 6 = 10(x - 2) hope this helps :)
Answer:
14 square units
Step-by-step explanation:
If you graph the points your triangle's height will be 4, and base would be 7.
<em>A = 1/2bh 4</em> x 7 = 28, 28 x 1/2 = 14.
Hope this helps :D

Answer:
+ 2 is a value for "C"
if the general form is ax^2 + bx +c and you want the A to be a positive integer...
then the c value would be -8
3x^2 - 8 = 0

Answer:
6seconds
Step-by-step explanation:
Given the height of an object modeled by the expression
h(x)=-5x^2+20x+60
The height of the object on the ground is zero i.e h(x) = 0
On substituting
h(x)=-5x^2+20x+60
0 =-5x^2+20x+60
Multiply through by -1
5x^2-20x- 60 = 0
Divide through by 5
x^2 - 4x - 12 = 0
x^2 - 6x + 2x - 12 = 0
x(x-6)+2(x-6) = 0
(x-6)(x+2) = 0
x - 6 = 0 and x+2 = 0
x = 6 and -2
Since time cannot be negative, hence it takes 6seconds after launch for the object land to on the ground
