In the given graph :
y - intercept of the line (c) is :
- 2
let's find slope (m) :
now, let's equate it with general equation to find the equation of line,
- y = mx + c
m = -2
c = 2
therefore, the equation of line will be :
- y = -2x + 2

The equation that can be used to represent the area of the triangle is A(x) = 0.5(f ∙ g)(x) ⇒ 2nd answer
Step-by-step explanation:
The formula of the area of a triangle is A = b h, where
- b is the length of the base of the triangle
- h is the length of the height of the triangle
∵ The area of the triangle when x = 2 is 14
∴ The base and the height of the triangle are functions of x
Assume that the length of the base of the triangle is represented by f(x) and the length of the height of the triangle is represented by g(x)
∵ A = = b h
∵ b = f(x)
∵ h = g(x)
- Substitute b by f(x) and h by g(x) in the rule and replace A by
A(x) because the area of the triangle is a function of x
∴ A(x) = f(x) . g(x)
∵ f(x) . g(x) can be written as (f . g)(x)
∴ A = (f . g)(x)
∵ = 0.5
∴ A = 0.5(f . g)(x)
The equation that can be used to represent the area of the triangle is A(x) = 0.5(f ∙ g)(x)

Answer:
Jenny to do it alone in 18.96 hours
and Lea take it 11 hours
and both can do in 6.96 hours
Step-by-step explanation:
given data
both work complete in = 6.96 hours
to find out
how long it would have taken Lea 11 hours and how long it would take Jenny to do it alone would take Jessica to do it alone
solution
we know both can do complete work in 6.96 hours
so in 1 hour they work part
and if Lea do it in 11 hours
so Lea do in 1 hours = part
we consider jenny do work in x hours
so in 1 hour it complete = part
so total work in 1 hour will be
+
=
solve we get x
x = 18.95
so Jenny to do it alone in 18.96 hours
and Lea take it 11 hours
and both can do in 6.96 hours
