Answer:

[tex]\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7[/tex]

Step-by-step explanation:

Given

[tex]\frac{3x^6}{6x^{-1}}[/tex]

Required

Solve

In laws of indices, we have:

[tex]\frac{x^m}{x^n} = x^{m-n}[/tex]

So, the expression becomes:

[tex]\frac{3x^{6 - (-1)}}{6}[/tex]

[tex]\frac{3x^{6 +1}}{6}[/tex]

[tex]\frac{3x^7}{6}[/tex]

Divide 3 and 6 by 3

[tex]\frac{1x^7}{2}[/tex]

[tex]\frac{x^7}{2}[/tex]

This can be rewritten as:

[tex]\frac{1}{2}x^7[/tex]

Hence:

[tex]\frac{3x^6}{6x^{-1}}= \frac{1}{2}x^7[/tex]

The sum of the series is 5, the correct option is D.

A sequence of numbers such that the consecutive term is increasing or decreasing by a fixed ratio is called a geometric series.

The summation of the series is obtained by the expression k²-1

For [tex]\sum_{1\to 3} k = k^2 -3[/tex]

By adding the terms of the series

The terms of the series from 1 to 3 is -2, 1, 6

On adding the terms

=>  -2 + 1 +6

= 5

The correct matrix addition is (m -1) + (( -12) + 0) = 12 .

Option B is correct.

To add two or more matrices, the basic process is matrix addition. Matrix addition is only possible if the matrices are in the same order. By order, we mean that the matrices have the same number of rows and columns. As a result, we can add the matrices' appropriate elements. Matrix addition is not possible if the order is changed.

We will add the rows:

Addition of First row

n + (4 -7) = 18

Addition of Second row

(m -1) + (( -12) + 0) = 12

Addition of Third row

(s+ 18) + (-18 - 11)= -28

Step-by-step explanation:

Answer:

The vehicle can travel 12 miles per gallon of gas.

Step-by-step explanation:

i.e.

[tex]1\frac{1}{8}=\frac{9}{8}[/tex] gallons

i.e.

[tex]13\frac{1}{2}=\frac{27}{2}[/tex] miles

Thus,

Total Gallons =9/8 gallons

Total Distance in miles = 27/2 miles

Hence:

Unit Rate = [27/2 miles] / [9/8 gallons]

                = 12 miles per gallons  ∵ [tex]\frac{27}{2}\div \frac{9}{8}=12[/tex]

Therefore, the vehicle can travel 12 miles per gallon of gas.

Step-by-step explanation:

Hey there!

Given equation is; 6x + y= 6.

6x + y -6=0........……(i)

Slope (m1) = (-coefficient of X)/(coefficient. of y)

Slope (m1) = (-6)/(1)

Therefore, slope of the equation is -6.

As per the condition of parallel lines, slope of 1st equation is equal to 2nd equation.

Therefore, m1=m2= -6

The another straight line passes through the point (2,-5). So to find the equation, use one-point formula.

(i.e (y-y1) = m2(x-x1)).

So, the equation is;

(y+5) = m2(x-2)

Now, we know that m1=m2= -6. Let's keep its value on it.

y+5 = -6(x-2)

Or, y+5 = -6x +12

Or, 6x+ y -7 = 0

Therefore, the equation which is parallel to 6x + y= 6 equation and passes through the point (2,-5) is 6x+y-7=0.
