Hello from MrBillDoesMath!
Answer:
(x-2)/(x-5)
Discussion:
Factor the numerator and denominator:
x^2 + x - 6 = (x+3)(x-2)
x^2-2x-15 = (x+3)(x-5)
So
(
x^2 + x - 6) / x^2-2x-15 = ( (x+3)(x-2) ) / ( (x+3)(x-5) )
Cancelling the (x+3) term in numerator and denominator gives
(x-2)/(x-5)

Answer:
what if he just doesnt say it at all. lol that would save some hard thinking.
Step-by-step explanation:
Given:
The cost to install x number of central air conditioning units for a company is given by the function
To find:
The cost to install 45 air conditioners.
Solution:
We have,
Putting x=45, we get
Therefore, the cost to install 45 air conditioners is $60433.33.
Answer:
depends on how much the sale is on for and the original price.
Step-by-step explanation:
Answer:
The equation of line having slope m and y-intercept b is
y = m x + b
The other two equations of line in the same family having intercepts p and q are,keeping the slope same i.e m , described in the question are
→ y= m x + p
→ y = m x + q
As both the equation have same slope i.e m , so lines will be parallel, but their Y - intercept are different i.e distance from the origin where it cuts the y-axis are different i.e at a distance of p and q from origin.
