write the equation In point slope form of the line with slope 2/5 and passing through the point (-8,1)

Dominik [7]

Point-slope:

y-y1= m(x-x1)

Plug in what you know.

y1= 1 and x1= -8

y-1= 2/5(x-(-8)
y-1= 2/5(x+8)

Distribute.

y-1=.4x+ 3.2 <- that is the final answer

I hope this helps!

The profit function p(x) of a tour operator is modeled by p(x) = −2x^2 + 700x − 10000, where x is the average number of tours he

pav-90 [236]

Answer:

Range of the average number of tours is between 150 and 200 including 150 and 200.

Step-by-step explanation:

Given:

The profit function is modeled as:

$p(x)=-2x^2+700x-10000$

The profit is at least $50,000.

So, as per question:

$p(x)\geq50000\\-2x^2 + 700x-10000\geq 50000\\-2x^2+700x-10000-50000\geq 0\\-2x^2+700x-60000\geq 0\\\\\textrm{Dividing by 2 on both sides, we get}\\\\-x^2+350x-30000\geq 0$

Now, rewriting the above inequality in terms of its factors, we get:

$-1(x-150)(x-200)\geq 0\\(x-150)(x-200)\leq 0$

Now,

$x0\\x>200,(x-150)(x-200)>0\\For\ 150\leq x\leq200,(x-150)(x-200)\leq 0\\\therefore x=[150,200]$

Therefore, the range of the average number of tours he must arrange per day to earn a monthly profit of at least $50,000 is between 150 and 200 including 150 and 200.
