Step-by-step explanation:

63+81

gcf = 9

63÷9=7, 81÷9=9

so, 63+81 = (9×7)+(9×9)

= 9×(7+9)

63+81 = 144

9x(7+9) = 9×16 = 144

Graph y=x, y=2x, and y=3x on the same coordinate plane. How are the graphs alike? How are they different? Compare the slopes.
Ne4ueva [31]

Answer:

all the three graphs passes through the origin (0,0)

the slope of the lines are different.

for y=x equation , slope =1

for y=2x equation slope = 2

for y=3x equation slope = 3

Step-by-step explanation:

LEts graph all the three equations

y=x , y=2x, y= 3x

Make a table for each equation and find two points

x           y=x                            x        y= 2x                          x       y=3x

0           0                               0         0                                0        0

1            1                                 1            2                               1          3

Graph is attached below

From the graph we can see that , all the three graphs passes through the origin (0,0)

From the graph we can see that the steepness of the line changes for each line. steepness of the line is noting but the slope . So the slope of the lines are different.

Given equation is in the form of y=mx+b

m is the slope

for y=x equation , slope =1

for y=2x equation slope = 2

for y=3x equation slope = 3

Is the time is takes you to run a 100-meter race function of the speed you run?
valina [46]

Answer:

Step-by-step explanation:

The simple answer is "yes".

The reason is that Distance = Speed (Velocity) * time taken.

d = v*t

Given that the distance is fixed, the velocity and time become inversely related such that an increase in velocity will mean that the distance is covered in a shorter time while an increase in time will mean that the distance is covered at a slower velocity.

Which of these is a formula that can be used to determine the nth term of the sequence 15, 27, 39, 51,...?
polet [3.4K]

Answer:

<em>an= 3+12n </em>

Step-by-step explanation: <em>the sequence is 15,27,39,51 The first term is : a 1= 15 The common difference of this sequence : d= 27 - 15 </em>

<em>The nth term of an arithmetic sequence is given by formula an= a + (n - 1 ) d . so a n for the sequence will be : </em>

<em>an =15+ (n-1) 12 </em>

<em>an = (15)+12n - 12</em>

<em>an = 3 + 12n</em>
