if y is directly proportional to x and y = 56 when x = 8 what is the value of y when x = 13

Answer:

x=-6

Step-by-step explanation:

use distributive property on the () and times x and 1 by three

then you subtract 6 from both sides

then subtract three from both sides

then divide both sides by 3

your work would look like this:

3(x+1)+6=-9

3x+3+6=-9

3x+3=-15

3x=-18

x=-6

Hope this helps!

Answer:

X=6

Step-by-step explanation:

3(x+1)+6=−9

Step 1: Simplify both sides of the equation.

3(x+1)+69(3)(x)+(3)(1)+6=−9

(Distribute)

3x+3+6=−9(3x)+(3+6)=−9

(Combine Like Terms)

3x+9=−93x+9=−9

Step 2: Subtract 9 from both sides.

3x+9−9=−9−93x=−18

Step 3: Divide both sides by 3.

3x3=−18/3

x=−6

Answer:

the answer is -1285

Step-by-step explanation:

unfortunately i do not have a number line but the equation -1310+25 can also be written as 25-1310.

think of it like doing 1310-25 which is positive 1285. because the negative sign is on the bigger number, the answer should be negative, making the sum -1285.

hope this helps!!

Answer:

The answer is Sometimes True.

Step-by-step explanation:

Radicals are number that have roots (√) .

Irrational are numbers that cannot be written in a form of fraction (a/b) .

I will show you some examples :

√2 × √2 = 2 (rational)

√2 × √5 = √10 (irrational)

Therefore, the products of 2 radicals will sometimes give rational or irrational numbers.

Answer:

6, 8 , 10

Step-by-step explanation:

smallest = x

medium = x+2

largest = x+4

The smallest integer and twice the second is 12 more than the third:

x + 2(x+2)  = 12+ (x+4)

x + 2x + 4  = x +16

3x  +  4 = x + 16

2x =  12

x = 6

Step-by-step explanation:

Answer:

7,065 meters.

Step-by-step explanation:

The problem is asking for "the difference" between two points. "The difference" means you're subtracting. The second point says it is below sea level, though. That makes it a negative number. Thus:

[tex]6960-(-105)=x[/tex]

When subtracting by a negative number, think of it as addition, since the negative cancels out the subtraction sign. This turns it into:

[tex]6960+105=7065[/tex]

There is a 7,065 meter difference between the two points.

Answer:

y=1/2x-7

Step-by-step explanation:

slope intercept form: y=mx+b

mx= slope

b= y-intercept

y=1/2x+b

Now plug in 6 for x and -4 for y bc 6 is in the x-value and -4 is in the y-value.

-4=1/2(6)+b

-4=3+b

Subtract 3 from both sides

b=-7

y=1/2x-7

The equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.

To find the equation of a line with a slope of 1/2 that passes through the point (6, -4), we can use the point-slope form of a linear equation, which is:

y - y₁ = m(x - x₁)

Plugging in the values, we have:

y - (-4) = 1/2(x - 6)

y + 4 = 1/2(x - 6)

Now, let's convert the equation to slope-intercept form, which is in the form of y = mx + b, where m represents the slope and b represents the y-intercept.

Expanding and rearranging the equation:

y + 4 = 1/2x - 3

y = 1/2x - 7

Therefore, the equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.

Step-by-step explanation:4/9

Answer:

43 Is a prime number

Answer:

$3

Step-by-step explanation:

To find the value of the tip, multiply 200 by 15%.

200 x 15% = 30

Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)

30 / 10 = 3

Each person should contribute $3 toward the tip.

Each person will contribute $23.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Bill= $200

Tip= 15%

So, the amount of bill be paid after tip

= 200+ 200 x 15%

= 200+ 200 x 15/100

= 230

Now, each of them have to pay

= 230/ 10

= $23

Hence, Each of them paid $23.
