 this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5

1)We solve the first equation: 
2x-1=5
2x=5+1
2x=6
x=6/2
x=2

2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2

The solutions of this equation /2x-1/=5 will be: x=3 and x=-2

Answer: x=3 and x=-2

In the solution, 3b + 9c = 3(b + 3). What should be done to make it CORRECT?
stiks02 [169]

Answer:

The second term of the binomial factor should be 3c instead of 3.

Step-by-step explanation:

Distributive property:

a*b + a*c = a*(b +c)

3b + 9c = 3*b + 3* 3 *c = 3*(b + 3c)

He cost, in millions of dollars, of building a three-story high school in new york state was estimated to be c(x) = 2.1 + 0.12x
ratelena [41]

Given cost function is

c(x) = 2.1 + 0.12x - 0.0001x^2 (20 ≤ x ≤ 400)

where x is the number of thousands of square feet

total revenue will be $0.2 million dollars per thousand square feet

Revenue is 0.2 millions per thousand square feet. we know x is the number of thousand of square feet

So R(x) = 0.2x

We know Profit = Revenue - Cost

P(x) = R(x) - C(x)

P(x) = 0.2x - (2.1 + 0.12x - 0.0001x^2)

P(x) = 0.2x - 2.1 - 0.12x + 0.0001x^2)

combine like terms

P(x) =-2.1 + 0.08x + 0.0001x^2

Profit function is

P(x) =0.0001x^2 + 0.08x - 2.1
