Option C:

$\frac{3 a^{2} b^{11}}{2 }$ is equivalent to the given expression.

Solution:

Given expression:

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}$

To find which expression is equivalent to the given expression.

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}$

Using exponent rule: $\frac{1}{a^m}=a^{-m}, \ \ \frac{1}{a^{-m}}=a^{m}$

$$=\frac{-18 a^{-2} b^{5}a^{4} b^{6}}{-12 }$

$$=\frac{-18 a^{-2} a^{4} b^{5} b^{6}}{-12 }$

Using exponent rule: ${a^m}\cdot{a^n}=a^{m+n}$

$$=\frac{-18 a^{(-2+4)} b^{(5+6)}}{-12 }$

$$=\frac{-18 a^{2} b^{11}}{-12 }$

Divide both numerator and denominator by the common factor –6.

$$=\frac{3 a^{2} b^{11}}{2 }$

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}=\frac{3 a^{2} b^{11}}{2 }$

Therefore, $\frac{3 a^{2} b^{11}}{2 }$ is equivalent to the given expression.

Hence Option C is the correct answer.

The histogram below shows the number of properties in a town that sold within certain time periods.

Tomtit [17]

Answer:

Option c) The scale on the y-axis misrepresents the difference in the heights of the bars.

Step-by-step explanation:

Given is a histogram that shows the number of properties in a town that are sold within certain periods.

On x axis is given number of days to sell and on y axis the number of properties

X axis is given in interval form with interval width 30 and on y axis scales are marked as 0,1,2....12,13 etc

The mistake is on y axis after 0, 10 is marked with unit distance from 0 but from 10 to 11 also distance is shown as 1 unit.

Hence correct option is

Option c) The scale on the y-axis misrepresents the difference in the heights of the bars.

Answer:

$x-6y=-9$

Correct answer: Option b

Step-by-step explanation:

Equation Of A Line

The standard equation of a line is given by

$y=mx+b$

Where m is the slope of the line and can be computed as

$\displaystyle m=\frac{d-b}{c-a}$

Where (a,b), (c,d) are two known points of the line. Let's use the points (-3, 1), (3, 2)

$\displaystyle m=\frac{2-1}{3+3}$

$\displaystyle m=\frac{1}{6}$

The value of b can be obtained by using any point and the value of m. Let's use (3,2)

$\displaystyle 2=\frac{1}{6}(3)+b$

$b=2-\frac{1}{2}=\frac{3}{2}$

The equation of the line is

$y=\frac{1}{6}x+\frac{3}{2}$

Multiplying by 6

$6y=x+9$

Rearranging

$x-6y=-9$

Correct answer: Option b
