Answer:

The slope of the line is 2. It means Jan runs 2 laps every minute.

Step-by-step explanation:

From the given graph it is noticed that the line passing through the points (2,4) and (5,10).

The slope of lines is

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope of given line is

$m=\frac{10-4}{5-2}$

$m=\frac{6}{3}$

$m=2$

The slope of the line is 2.

In the given graph x axis represents the time in min and y-axis represents the laps run. The slope defines the number of laps in each minute.

The slope is 2, it means Jan runs 2 laps every minute.

Solve the system by elimination find the ordered pair that is the solution

Amanda [17]

Answer:

x = 1

y = -24

Step-by-step explanation:

8x + y = -16

-3x + y = -5

Subtract equation one from equation two

8x - -3x + y - y = -16 - - 5

8x + 3x = -16 + 5

11x = 11

Divide both sides by 11

11x/11 = 11/11

x = 1

Now substitute 1 for x in either of the equations to get y.

Using equation one, we have

8x + y = -16

8 x 1 + y = -16

8 + y = -16

Subtract 8 from both sides

8 - 8 + y = -16 - 8

y = -24

x = 1

y = -24

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.
