9 + 15 using the distributive property to factor out the greatest common factor

Answers

Answer:

    24

Step-by-step explanation:

9 can be broken down to 3 because 3 x 3 = 9

15 can be broken down to 3 also because 3 x 5 = 15

> 9 + 15

= 3 ( 3 ) + 3 ( 5 )

= 3 ( 3 + 5 )

= 3 ( 8 )

= 24

Which answer describes the sequence {1,3,7,15,…} as a mathematical statement?

Answers

Answer:

so just successive powers of 2

Step-by-step explanation:

1, 3, 7, 15, 31, 63, _? Add successive powers of 2 to the number: 1+2=3; 3+4=7; 7+8=15; 15+16=31; 31+32=63; 63+64=127.

The given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

Given that,

To justify the given sequences 1,3,7,15.


What is arithmetic progression?

Arithmetic progression is the series of numbers that have common differences between adjacent values

What is geometric progression?

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Here,
Given a sequence, 1,3,7,15
where first term      A0 = 1
         second term  A1 = 1 + 2 = 3
          third term      A2 = 3 + 4 = 7
From above sequence we can conclude the general term for the sequence as, S = A(n-1) + (A(n-1) + 1)

Thus, the given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

Manny begins the summer with $200 in his savings account. Each week he adds $85 to his account. Susan begins the summer with $95 in a savings account and adds $100 each week. When will Manny and Susan have the same amount of money in their accounts? ​

Answers

Answer:

7 weeks

Step-by-step explanation:

200 + 85w = 95 + 100w

-95     -85w  -95    -85w

105 = 15w     (divide both sides by 15)

7 = w

What is the equation of the line perpendicular to Y= 1/2x +6 that passes through the point (4,1)

Answers

Answer:

Step-by-step explanation:

y= mx+b is the general equation where m is the slope

y= 1/2 x +6 has the slope 1/2

perpendicular lines have the slope negative reciprocal

so the slope of the ⊥ line is -2

y = -x +b , yet for point (4, 1) the x=4 and y =1

1= -4 +b so b= 5

the equation of the ⊥ line is y= -2x+5

Find the solution to the system: y=4x and 3x+2y=55

Answers

Answer:

x = 5, y = 20

Step-by-step explanation:

if y = 4x and 3x+2y = 55 then we can subtitude y as x.

We know that y = 4x so we can write 4x wherever we see y.

3x + 2y = 3x + 2(4x) = 55

3x + 8x = 55

11x = 55

x = 5.

And if y = 4x = 4(5)

y = 20
