. What is the y intercept of the line represented by the equation 3x+2y = 6?

Mathematics
1 answer:
Alla [95]3 years ago
5 0

Answer:

3

Step-by-step explanation:

To identify the y-intercept represented by the given equation, we need to get the equation into slope-intercept from:

y=mx+b

m=slope

b=y-intercept

Start with:

3x+2y=6

Subtract 3x from both sides of the equation:

2y=-3x+6

Divide both sides of the equation by the coefficient of y, which is 2:

y=-1.5x+3

Identify the y-intercept:

b=3

mihalych1998 [28]
<span>Let x be the second number.
Let 2x+7 be the first number.

x+2x+7=25
3x+7=25

3x=25-7
3x=18
x=18/3
x=6
2x+7=19

Iteru [2.4K]

Answer:pretty sure its 20

Step-by-step explanation: so i took 7 and multiplied it by 2 because that is how much is sold every day and got 14. then added six to that and got 20. then i wrote this on my paper:

20  18  16  14  12  10  8  

S    M   T   W   T   F   S  

so by Saturday you should have 8 and that would leave you 6 on sunday after you sell 2. does that make sense?

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so
mamaluj [8]

Answer:

1) Is the pattern an arithmetic sequence?​

Yes it is

2)Identify a and d.​

a = First term = 2

d = Common difference = 2

3) Write the 50th term of the sequence.​

50th term = 100

4) Find the total number of logs in the first 10 rows.​

= 1010 logs

Step-by-step explanation:

Is the pattern an arithmetic sequence?​

Yes it is

2) Identify a and d.​

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,

The formula for arithmetic sequence =

an = a+ (n - 1)d

a = First term

d = Common difference

For the above question:

a = 2

d = Second term - First term

= 4 - 2

d = 2

3) Write the 50th term of the sequence.​

Using the formula for arithmetic sequence

an = a+ (n - 1)d

a = 2

n = 50

d = 2

a50 = 2 + (50 - 1)2

= 2 + (49)2

= 2 + 98

= 100

The 50th term = 100

4)Find the total number of logs in the first 10 rows.​

Sum of first n terms = n/2(a + l)

n = 10

a = first term = 2

We are told that there are 200 logs in the bottom row, hence:

l = last term = 200 logs

Hence,

Sn = 10/2×[ (2 + 200

= 5(202)

= 1010 logs

Which one is the positive slope A.) (2,-3,) and (1,-2), B.) (0,0) and (3,-3), C.) (-1,-1) and (5,4) , D.) (-3,0), (9,0)
bagirrra123 [75]

Answer:

C.

Step-by-step explanation:

Use slope = (y2-y1)/(x2-x1).

slope = (4 - -1)/(5 - -1)

slope = 5/6, positive

Hope this helps!
