Hey the very top one and there’s choice answers

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

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.

Hope it helps...

Answer:

[tex] - \frac{1}{6} [/tex]

Step-by-step explanation:

Multiplying a positive and a negative equals a negative: ( + ) × ( - ) = ( - )

[tex] - \frac{4}{9} \times \frac{3}{8} [/tex]

Reduce the number with the greatest common factor 4:

[tex] - \frac{1}{9} \times \frac{3}{2} [/tex]

Reduce the number with the greatest common factor 3:

[tex] - \frac{1}{3} \times \frac{1}{2} [/tex]

Multiplying the fractions:

[tex]1 \times 1 = 1 \\ 3 \times 2 = 6[/tex]

Therefore, the answer will be - 1/6.

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]

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.
