Find the next term of the series. question. 21,31,22,74?​

Mathematics
1 answer:
navik [9.2K]3 years ago
3 0

Answer:

1st rule:

21,31,22,74 => 12, 13, 22, 47

12 + 1^2 = 13

13 + 3^2 = 22

22 + 5^2 = 47

47 + 7^2 = 96

96 => 69

=> next number after 74 is 69

2nd rule:

21, 31, 22, 74

21 + 31 + 22 = 74

31 + 22 + 74 = 127

=> next number after 74 might also be 127

Which is a solution to the equation |10-5y|=20<br><br>y=2<br><br>y=4<br><br>y=6<br><br>y=10
Pavlova-9 [17]

Answer:

y=6

Step-by-step explanation:

|10-5y|=20

Since the absolute value is isolated, we can then separate the equations

For absolute values, there is a positive and negative when we remove the absolute values.

10-5y = 20          10-5y= -20

Subtract 10 from each side

10-10-5y = 20-10          10-10-5y= -20-10

-5y = 10                             -5y = -30

Divide by -5

-5y/-5 =10/-5                    -5y = -30/-5

y =-2                                      y =6

Through:(-1, -2), slope = 5
kherson [118]

Answer:

y=5x+3

Step-by-step explanation:

Hi there!

We're given the point (-1, -2) and a slope of 5. We need to find the equation of the line in slope intercept form.

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

Since we're already given the slope, we can substitute that immediately into the equation

here it is so far:

y=5x+b

now we need to solve for b

Since the line will pass through the point (-1,-2), we can use it to solve for b

substitute -1 as x and -2 as y into the equation

-2=5(-1)+b

multiply

-2=-5+b

add 5 to both sides

3=b

substitute that into the equation

therefore, the equation of the line is <u>y=5x+3</u>

Hope this helps! :)
