8. Let f(x) = 3x + 2 and g(x) = x - 3. Find f(x) - g(x) and state its domain.

1 answer:

7 0

F(x) - g(x)
becomes
(3x + 2) - (x - 3)

which is
3x + 2 - x + 3

then add like terms
2x + 5

so f(x) - g(x) = 2x + 5
and it's domain should be all real numbers

A plot of land is in the shape of a triangle. If one side is x meters, a second side (5x−3) meters, and a third side is ( 7x −

liubo4ka [24]

Given, the plot is in the shape of triangle.

First side = x meter

Second side = ( 5x-3 )meters

Third side = ( 7x-6 ) meters

Perimeter of triangle is equal to the sum of all the three sides.

Perimeter = $x + (5x-3) + (7x-6)$

Combine like terms by adding all the x terms together and all the constant terms together.

Perimeter = $(x+5x+7x) + ( -3 -6 )$

Perimeter = $13x - 9$ feet ... Answer

15c² - 5c. Factorise completely

KATRIN_1 [288]

Looking at the problem, what we must do to complete this question is to completely factor the expression that was provided. The expression that was provided is $15c^2 - 5c$ .

The first step that we must do is to take a look at the expression and see what the two pieces of the expression have in common. We can see that both $15c^2$ and $-5c$ have the number 5 and the variable c associated with them so we can factor out those two.
