1.) 4, 2, 1, 1/2, 1/4,... 2.)2, 6, 18, 54, 162, ...
3.) -4, -16, -64, -256, ... are geometric sequences because common ratio is same. Example: 1.) ratio of 1st and 2nd term is 1/2. Similarly ratio of 3rd and 4th term is 1/2 and so on.

ANSWER:

4, 2, 1 , 1 / 2, 1 / 4 ... Common Ratio = 1 / 2

2, 6, 18, 54, 162 ... Common Ratio = 3

- 4, - 16, - 64, - 256 ... Common Ratio = 4

As these sequences have common ratios which remain the same across the whole sequence, they are geometric sequences.

Write the equation of the line that passes through (7,6) and (-1,2) in slope intercept form​
Olin [163]

The equation of line passing through (7,6) and (-1,2) in slope intercept form is:

y=\frac{1}{2}x+\frac{5}{2}

Step-by-step explanation:

Given

(x1,y1) = (7,6)

(x2,y2) = (-1,2)

The general form of slope-intercept form of equation is:

y=mx+b

We have to find the slope first

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-6}{-1-7}\\\\m=\frac{-4}{-8}\\\\m=\frac{1}{2}

Putting the value of slope in the equation

y=\frac{1}{2}x+b

To find the value of b, putting (-1,2) in the equation

2=\frac{1}{2}(-1)+b\\2=-\frac{1}{2}+b\\2+\frac{1}{2}=b\\b=\frac{4+1}{2}\\b=\frac{5}{2}

Putting the value of m and b in equation

y=\frac{1}{2}x+\frac{5}{2}

The equation of line passing through (7,6) and (-1,2) in slope intercept form is:

y=\frac{1}{2}x+\frac{5}{2}

There are 364 first-grade students in Park Elementary School. If there are 26 more girls than boys, how many girls are there?
wlad13 [49]

Answer:

195

Step-by-step explanation:

If there are x boys, then there are x+26 girls. Hence, we write the equation,

x+(x+26)=364

Solve for x:    

        2x+26=364

            2x-338

             x=169

So there are 169+26 =195 girls

Your car gets 15 miles to the gallon and your friend's car gets 25 miles to the gallon. you decide to go on a road trip to virgi
sergij07 [2.7K]

You would save $32 if you used your friends car.

I found this out by doing this:

300/15 will tell you how many gallons of gas it would take to get to Virginia Tech in your car(20 gallons). You would then multiply that by the price of gas($4), which would = $80.

300/25 will tell you how many gallons of gas it would take to get to Virginia Tech in your friends car(12 gallons). You would then multiply that by the price of gas($4), which would = $48.

So to come up with the difference you would do $80-$48, which is $32.

I hope this helped Tinytoonjr6552!
