Question 4 of 32 Jacob is a construction worker who earns a yearly income given by the expression 2000x + 3000, where x is the n
ELEN [110]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the expression :

Jacob's yearly income :

2000x + 3000 ; x = number of hours worked per week.

Carlos income :

3800x - 40000

Managers prediction = 35

Jacob.: 2000(35) + 3000 = 73000

Carlos : 3800(35) - 40000 = 93000

Carlos will earn more than Jacob given the manager's prediction.

Number of hours required so they can earn the same amount :

2000x + 3000 = 3800x - 40000

3000 + 40000 = 3800x - 2000x

43000 = 1800x

x = 43000/1800

x = 23.88

x = 24 hours

When 27 times x squared times z all over negative 3 times x squared times z to the sixth power is completely simplified, the exp
marysya [2.9K]

Answer:

  -5 or 5 depending on how you write the simplified form

Step-by-step explanation:

\dfrac{27x^2z}{3x^2z^6}=9x^{2-2}z^{1-6}\\\\\boxed{=9z^{-5}=\dfrac{9}{z^5}}

__

The applicable rules of exponents are ...

  (a^b)(a^c) = a^(b+c)

  1/a^b = a^-b

__

Some folks like their simplified form to contain only positive exponents. Other folks avoid unnecessary fractions. Choose the form that satisfies your grader.

Which of the following functions has the function rule y=x+4? (-2, 2), (-1,-5), (3.7)} {(-3, 1), (0.4), (2. 6)) (12.6). (-3.-7),
PSYCHO15rus [73]

Answer:

{(-3, 1), (0, 4), (2, 6)}

Step-by-step explanation:

I wasn't exactly sure how the points were divided up, but assuming there are 4 groups of 3, this is the correct answer. Each point follows the form (x, x+4), so they all fit the equation y = x + 4.
