Answer:

y-4=(-1/2)(x-4)

Step-by-step explanation:

Slope=(8-4)/(-4-4)=-4/8=-1/2

The equation of the line is y-4=(-1/2)(x-4)

Answer: 18

Step-by-step explanation: -8,2 is 18 away from 10,2 because -8 is 18 away from 10

Answer:

74

Step-by-step explanation:

3 3/7 , 4 2/7, 5 1/7, .... 66

=> could be changed into :

24/7, 30/7, 36/7, ...... 462/7

let the numbers = n

462 = 24 + (n-1)(6)

462 = 24 + 6n -6

462 = 6n +18

6n=462-18

6n = 444

n = 444/6 = 74

Answer: 2 : 1

Step-by-step explanation:

24 and 12 both are divisible by 12 so

Divide 24 / 12 and 12 / 12

= 2 : 1

Answer:

It is an irrational number, [tex]\sqrt{3}[/tex] as a decimal rounded to the tenth place is 1.7

Step-by-step explanation:

All square roots are irrational numbers

Step-by-step explanation:

y = ax +b

2 = 0a+ b => b = 2

4 = -2a + b

4 = -2a +2

2a = 2-4

2a = -2

a = -1

so, y = -x + 2

Answer: p=2

Step-by-step explanation:

4.05p+14.40=4.50p+13.50

4.50p-4.50p=13.50-14.40

-0.45p=-0.90

p=-90/-0.45

p=2

Answer:

Step-by-step explanation:

Given polynomial:

Convert this into standard form, order in descending powers:

The leading term, -2x⁹ is the one with the greatest power. Its coefficient, -2 is the leading coefficient.

[tex]\\ \rm\longmapsto 3x^6-2x^9+5x-12[/tex]

Write in standard form

[tex]\\ \rm\longmapsto -2x^9+3x^6+5x-12[/tex]

-2x has greatest degree hence leading coefficient is -2.

Answer: Therefore,

1 + (-5/8)

Solve it,

= 1-(5/8)

= (8-5)/8

= 3/8

Answer:

-6+3 because you can distribute the negative sign into the parenthesis and make it a positive.

Answer:

So the answer would be -6+3

Step-by-step explanation:

Here's why:

So think of this strategy when working with these problems

Draw the line connect the sign

This means to convert the -(- into a plus sign, which makes these problems way easier

So that's why the answer is -6+3

Answer = -3

Answer:

3x10^-3

Step-by-step explanation:

Answer:

485 × [tex]10^{-10}[/tex]

Step-by-step explanation:

first we need to convert the number to fraction

0.0000000485

[tex]\frac{0.0000000485}{10000000000}[/tex]

it will be

[tex]\frac{485}{10000000000}[/tex]

or can be written as

[tex]\frac{485}{10^{10} }[/tex]

now we need to convert it to scientific notation

485 × [tex]10^{-10}[/tex]

Answer:

81

Step-by-step explanation:

it can be expressed as a product of two smaller numbers 9×9

Answer:

1. rounds down to 600 = 601 - 649

2. The digit in the ones place is the third odd number that you count beginning with 1. = 605

3. The sum of the digits is 13

Answer:

625

Step-by-step explanation:

Firstly, I found the ones place because I just needed to know the third odd number starting from 1. The first odd number is 1 then 3 and then 5, so I know that the digit in the ones place is 5.

Ones place: 3rd odd number: 1, 3, 5

Then, I looked at the hundreds place, because I know that it is rounded to down to 600 in the nearest hundred, I know it has to be 649 or smaller and bigger than 600. In the range of 600-649, the hundreds place remains the same, and therefore I know that the digit in the hundreds place is 6

Finally, to determine the tens place, I can do 13-(6+5) I can do this because I know that the sum of the digits is 13. Because 13-11=2, I know that the digit in the tens place is 2

Final number: 625

Answer:

a. x=35

b. x=4

c. x=30

Step-by-step explanation:

6a) 7/9=x/45

7/9×45=x

7×45/9=x

315/9=x

35=x

x=35

————————

b. 10/8=5/x

5/4=5/x

5/4x=5(the x is in the middle of the division sign here)

5x/4=5(the x is NOT in the middle of the division sign)

5x=5×4

5x=20

x=20/5

x=4

———————

c. x/34=15/17

x=15/17×34

x=15×34/17

x=510/17

x=30

accoding to the web "He started out 25 meters below the edge of the volcano. It takes him 6.25 seconds to reach the edge."

Answer:

25 meters below the edge; 6.25 seconds  

Step-by-step explanation:

We can represent this with a linear function in slope-intercept form.  

We know the rate of change is 4 since he climbs up at 4 meters per second.  We do not know the value of b, the y-intercept.  

This gives us  

y = 4x + b  

We know that he is 13 meters below the edge after 3 seconds.  Using -13 for y and 3 for x,  

-13 = 4(3) + b  

-13 = 12 + b  

Subtract 12 from each side:  

-13-12 = 12+b-12  

-25 = b  

This gives us the equation  

y = 4x - 25  

He started out 25 meters below the edge of the volcano.  

To find how long it took him to reach the edge, substitute 0 in for y:  

0 = 4x - 25  

Add 25 to each side:  

0+25 = 4x-25+25  

25 = 4x  

Divide both sides by 4:  

25/4 = 4x/4  

6.25 = x  

It takes him 6.25 seconds to reach the edge.

The correct equation that Jordan can use to solve the division problem 42 divided by 7 is:

? x 7 = 42

So, the correct equation is option 3) ? x 7 = 42.

Given that, Jordan has to solve this division problem: 42 divided by 7 = ?

In this case, Jordan needs to find the value of the missing factor, which represents how many times 7 can be multiplied to get 42.

Therefore, he can use the equation:

? x 7 = 42

This equation represents the inverse operation of division, which is multiplication.

When we know one factor (7) and the product (42), we can use multiplication to find the missing factor (the quotient).

By solving for the missing factor, he will find the correct answer to the division problem:

The missing factor = 42 / 7 = 6

So, the correct equation is option 3) ? x 7 = 42.

Steps:

6 1/4 - 4 3/15 can also be written as 25/4 - 23/5

The LCD of 4 and 5 is 20.

That gives us 125/20 - 92/20.

Now, just subtract the numerators (leave the denominators the same).

That brings us to 33/20, which can be simplified to 1 13/20

Answer:

1 [tex]\frac{13}{20}[/tex]

Step-by-step explanation:

1. Convert both [tex]\frac{1}{4}[/tex] and [tex]\frac{3}{5}[/tex] into a common denominator. 4 multiplied by 5 is 20. 20 works for both 4 and five. So convert the denominator into 20. Multiply [tex]\frac{1}{4}[/tex] by [tex]\frac{5}{5}[/tex] and multiply [tex]\frac{3}{5}[/tex] by [tex]\frac{4}{4}[/tex]

2. You should've gotten, [tex]\frac{5}{20}[/tex] and [tex]\frac{12}{20}[/tex]

3. 6 - 4 = 2, so 2 [tex]\frac{5}{20}[/tex] - [tex]\frac{12}{20}[/tex]

4. You have to convert 1 into [tex]\frac{20}{20}[/tex] and add that to [tex]\frac{5}{20}[/tex]. You should've got [tex]\frac{25}{20}[/tex]

5. Subtract.

The Answer is 1 [tex]\frac{13}{20}[/tex]
