On Average, Mercury is about 57,000,000 Km from the sun, whereas Neptune is about 4.5 x 10^9 km from the sun. What is the difference between Mercury’s and Neptune’s distances from the sun?

Answer:

y = mx + b slope(m) = 1/2 (-2,1)...x = -2 and y = 1 now we sub and solve for b, the y int 1 = 1/2(-2) + b 1 = -1 + b 1 + 1 = b 2 = b so ur equation is : y = 1/2x + 2 <== here is one answer y - y1 = m(x - x1) (slope(m) = 1/2 (-2,1)...x1 = -2 and y1 = 1 now we sub y - 1 = 1/2(x - (-2) = y - 1 = 1/2(x + 2) <== here is another answer

Answer:

-30.78!

Step-by-step explanation:

Answer:

B) n=-2

Step-by-step explanation:

First, distribute.

7(1+4n)-5=-38+8n

7+28n-5=-38+8n

Combine like terms.

2+28n=-38+8n

To make solving the equation easier, subtract 8n first, so there isn't a negative variable.

2+28n=-38+8n

  -8n           -8n

2+20n=-38

Subtract 2 on both sides.

2+20n=-38

-2          -2

20n=-40

Divide by 20 on both sides.

20n=-40

/20   /20

n=-2

Hope this helps!! Have a wonderful day :3

Step-by-step explanation:

-6a - 4(a - 3) = -6a + 15

=> -6a - 4a + 12 + 6a - 15 = 0

=> -4a - 3 = 0

=> -4a = 3

=> a = -3/4

Answer:

-2=2

Step-by-step explanation:

Answer:

w = 3

Step-by-step explanation:

-5w + 3 = 4w - 6

were going to get the variable and the numbers on different sides

-5w + 3 - 3 = -5w

4w - 6 - 4w = -6

-5w + 4w = -1w or -w

-6 + 3 = -3

-w = -3

and since there're both negatives you can just take that away and you get

w = 3

x-intercept(s): (3,0)

y-intercept(s): (0,−9)

Answer:

The x is -3 and the y is -9 so the answer is (-3,-9)

Step-by-step explanation:

6x-2y=18

-6x       -6x

-2y=-6x+18

-2y/-2=-6x/-2+18/-2

y= -3x -9

To graph you just mark it at -9 and go down 3 up 1; or you could go up 3 down 1

Hope this helps :) Have a wonderful day and  wish you luck on your test :)

Answer:

2

Step-by-step explanation:

2 is the highest number that can divide betwwen 6 and 4.

Answer:

2x-4= 7x-34

30=5x

6=x

Step-by-step explanation:

bring the variables to one side and numbers to the other by either subrtracting or adding depending on the values.

now divide 5 on both sides

now you have the answer

I hope this helps!

Answer:

7.7 is the answer

Step-by-step explanation:

(credit to manics.info)

Step 1:

Calculate the square root of 60 to be:

√60 = 7.74596669241483

Step 2:

Reduce the tail of the answer above to two numbers after the decimal point:

7.74

Step 3:

Round 7.74 so you only have one digit after the decimal point to get the answer:

7.7

To check that the answer is correct, use your calculator to confirm that 7.72 is about 60.

Hope this help and have a great day!

Answer:

24*10^5

Step-by-step explanation:

I would say Jessica

Step-by-step explanation:

Because Mia's grade dropped by 4% and Jessica's grade increased by 5%

1% difference in the grades

Answer:

(x - 5)² = 17

Step-by-step explanation:

Given

0 = - x² + 10x - 8 ( multiply through by - 1 to clear the leading negative )

x² - 10x + 8 = 0 ( subtract 8 from both sides )

x² - 10x = - 8

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 5)x + 25 = - 8 + 25

(x - 5)² = 17

Answer:

x=-1, x=3

Step-by-step explanation:

to solve by factoring:

1. swap the sides:  

0=(x-1)^2-4

2. expand the expression:  

(x-1)^2-4=0

3. rewrite and calculate:

x^2-2x+1-4=0

4. factor

x^2+x-3x-3=0

5. Factor... again

x(x+1)-3(x+1)=0

6. separate

(x+1) (x-3)=0

7. solve

x+1=0, x-3=0

8. and you end up with 2 solutions

x=-1, x=3

Answer:

x=-3

Step-by-step explanation:

I did it with the parenthesis to make it easier so..

Answer:

4

Step-by-step explanation:

hi! let's divide -24 and -6 to simplify this. this is the same answer as 24/6 since two negatives that are divided by each other equal a positive number, and 24 divided by 6 is 4, so the answer is 4.

Answer:

Step-by-step explanation:
