Answer:

direct

Step-by-step explanation:

The standard form of an equation representing direct variation is

y = kx ← k is the constant of variation

The standard form of an equation representing inverse variation is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]

Answer:

April 12th

Step-by-step explanation:

Answer:

Step-by-step explanation:

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

Answer:

14 girls

Step-by-step explanation:

I hope this helps!

Answer:

14 girls in the class

Step-by-step explanation:

use percentage equation, p = nw or part of the question = the percentage times the total amount.

So in this case our p, or girls in the class (which is part of the total), is unknown. We have the percentage and we have the total. So all we need to do is multipy them. However how do you multiply percentage . . . well 40 percent also equalts to 0.40. So all you have to do is multiply .40 by 35 and you have your answer.

Answer:

the mean of which the team won is 8.75

The mean of which the team lost is 11.5

Step-by-step explanation:

add all the numbers of which the team won by then divide the sum by the number of numbers there are

example:

7+8+11+9=35/4=8.75

Answer:

For 20 hours it would be $1,500.

Answer:

p = -4

Step-by-step explanation:

I'm not going to explain each step, just try to follow along.

31 = -(1+6p)+4(p+6)

31 = -1-6p+4p+24

7 = -1-2p

8 = -2p

p = -4

Answer:

Thats what i got too :)

Step-by-step explanation:

You have the correct answer. It is 80.3 square yards.

Work Shown:

Area of parallelogram = length*width = 21.5*33.6 = 722.4 sq ft

1 yard = 3 ft

1 sq yd = 9 sq ft ... square both sides

To convert from square feet to square yards, we'll divide by 9

This is the same as multiplying by 1/9

722.4 sq ft = (722.4 sq ft)*(1 sq yd/9 sq ft)

722.4 sq ft = (722.4)*(1/9) sq yards

722.4 sq ft = 80.2667 sq yards

722.4 sq ft = 80.3 sq yards

Answer:

-3x

Step-by-step explanation:

Answer:

Step-by-step explanation:

If we multiply any negative number in this case -3 times a POSITIVE we will always get a negative. So the positive we can put as x and multiply -3 times x = -3x.

Hope this helps :D

Answer:

26x47

Step-by-step explanation:

To calculate the length of the rectangle we would do 2(2x - 5) + 2(x) = 146

We simplify and get 6x - 10 = 146,

then divide both side by 6 and plus 10 both sides,

we will get

x = 26

Now we've found one of the length,

to find the other side we do 26 * 2 = 52, and subtract 52 from 146,

which would get 94, then we divide it by 2

94/2 = 47

The dimensions is 26x47

Add them in and try to solve for 7 and 6, for 8. I usually put all number on one side and all x on other side.

Answer:

The number 11 is not a solution for the given equation.

Step-by-step explanation:

We are given an equation with one variable. We can use simplifying processes to solve the equation.

[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]

We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.

[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]

Therefore, 11 is not a solution for the given equation.

Answer:

[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]

[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]

[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]

[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]

Answer:X=3

y= -4

Step-by-step explanation:

If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.

so solving for x, 4x=12--> x=3, since y=0 in this scenario.

Solving for y, x=0, so -3y=12--> y=(-4)

9514 1404 393

Answer:

  see below for a table

Step-by-step explanation:

You can easily identify intercept points by solving for one variable when the other is zero.

x-intercept (y=0)

  4x = 12

  x = 12/4 = 3

y-intercept (x=0)

  -3y = 12

  y = 12/-3 = -4

So, the coordinate pairs of these points are ...

  (3, 0) and (0, -4)

__

If you solve for y, you get ...

  -3y = 12 -4x

  y = (4/3)x -4 . . . . . divide by -3

This suggests that x being a multiple of 3 will be useful for finding integer values of y.

We already have points for x=0 and x=3. We can add points for x=6 and x=-3.

  y = 4/3(6) -4 = 4

  y = 4/3(-3) -4 = -8

So, the additional points are ...

  (6, 4) and (-3, -8)

Answer:

she made $68 last week.

Answer:

$68

Step-by-step explanation:

you need to divide 8 by 2 which is 4

then multiply 4 by 17 which equals 68.

The solution is where the two lines cross each other:

(-1,3) and (2,6)

The answer is B.

Answer:

6x+8y = 3

Step-by-step explanation:

we have 3x + 4y = 7

4y = -3x + 7

y = -3/4 x + 7/4

so slope is -3/4

2 parallel lines always have same slope

so the slope of our new line is -3/4

so y = -3/4 x + C

for c,

we have (x,y) = (-2/3,7/8)

7/8 = -3/4 * -2/3 + C

C = 3/8

so equation is

y = -3/4 x + 3/8

simplyfyig,

8y = -6x + 3

or, 6x+8y = 3
