Short Answer: (b - 7)(b + 1)

The answer will consist of 2 factors each of which is a binomial. Please don't take that comment personally. It is just on Brainly we are told to be accurate.

This factors by sight. You do not need the quadratic formula (but you could use it).

(b - 7)(b + 1) are the two factors that you need. When you remove the brackets, you get b^2 - 6b- 7 back.

b^2-6b-7=b^2+b-7b-7=b(b+1)-7(b+1)\\\\=\boxed{(b+1)(b-7)}

adelina 88 [10]
You're going to go to 50 on the y-axis and put a point there and then from 50 the slope needs to be a rise over run so go up 4 right 1:)

A company uses the function C(x)=20.50+2000, where C is the cost and x is the number of units it produces, to determine its dail
Kipish [7]
You left it out, but I'm thinking that there must be an 'x' next to the '20.50' in the function.  I'm so sure of it that I'll assume it, as I proceed to answer the question:

C(x) = 20.50x + 2,000

Subtract  2,000 from each side:      C - 2,000  =  20.50 x

Divide each side by  20.50 :        x  =  (C - 2,000) / 20.50

When C = $625,000 . . .

x = (625,000 - 2,000) / 20.50  =  623,000 / 20.50  =  30,390.2439

<em>30,390 complete units</em> are produced, and there are  5  bucks left over,
to split up among all the loyal employees who worked with such diligence and dedication to make it happen.  The company's senior management will graciously add each worker's share to his gross pay before taxes for the second month following the close of the current quarter, with a photocopied note inserted in the pay envelope, expressing management's sincere thanks to everyone, an admonition not to spend it all in one place, and a reminder that no matter how many festivals to their god they need to go out to the desert to celebrate, their tally of bricks for the next quarter shall not be diminished.

2/3 - 3/2y + 1/3y + 4 = 0​
Korvikt [17]

Answer:

y = 4

Step-by-step explanation:

(2/3 + 4) + (-3/2y + 1/3y) = 0

(-3/2y + 1/3y) = -4 2/3

-9/6y + 2/6y = -14/3

-7/6y = -14/3

cross-multiply:

-21y = -84

y = 4
