Which equation represents a line parallel to the line shown on the graph? On a coordinate plane, a line goes through (negative 6

ELEN [110]

Answer:

$\boxed{ \mathrm{y = \ negative \ 3 x + 3}}$

Step-by-step explanation:

The coordinates are (-6,0) and (-8,6)

<u><em>Finding slope of the line</em></u>

Slope = $\frac{rise}{run} = \frac{y2-y1}{x2-x1}$

Slope = $\frac{6-0}{-8+6}$

Slope = $\frac{6}{-2}$

Slope = -3

Parallel lines have equal slopes.

So, the line which is parallel to this line is y = negative 3 x + 3

the slipperiness of a floor (demoted by S) can be defined as a function of the number or banana peels (denoted by P) and the are

QveST [7]

We have been given that the slipperiness of a floor (demoted by S) can be defined as $S=\frac{P}{A}$

Here P= number or banana peels

A=area of the floor

Number of bananas peels can be measured (units ) in peels

Area can be measured in $m^2$

Since, slipperiness of a floor is the ratio of these two hence, we have

$\text{slipperiness of a floor}=\frac{\text{Peels}}{m^2}$

A is the correct option.

<h2>The required 'option C) 144' is correct.</h2>

Step-by-step explanation:

We have,

$(x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12$

To find, the possible value of x = ?

∴ $(x^{\dfrac{1}{8}})(x^{\dfrac{3}{8}})=12$

⇒ $x^{\dfrac{1}{8}+\dfrac{3}{8}}=12$

Using the exponential identity,

$a^{m} a^{n} =a^{m+n}$

⇒ $x^{\dfrac{1+3}{8}}=12$

⇒ $x^{\dfrac{4}{8}}=12$

⇒ $x^{\dfrac{1}{2}}=12$

Squaring both sides, we get

$(x^{\dfrac{1}{2}})^2=(12)^2$

⇒ $x^{{\dfrac{1}{2}}\times2}=144$

⇒ x = 144

∴ The possible value of x = 144

Thus, the required 'option C) 144' is correct.
