Answer: In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. ... In inverse variation, it's exactly the opposite: as one number increases, the other decreases. This is also called inverse proportion.

Step-by-step explanation:

Step-by-step explanation: Direct variation is the relationship between two variables such that the variables have a constant ratio, k, were k ≠ 0.

If we call our variables a and b, we can use the

following formulas to represent direct variation.

[tex]\frac{a}{b} = k[/tex] or [tex]b = ka[/tex]

Inverse variation is also a relationship between two variables but the difference is that as one variable increases, the other variable decreases.

Suppose that our variables are g and h.

As g increases, h will decrease or as g decreases, y will increase.

Answer:

I believe the slope of the line passing through the points is x= -3

Answer:

It's Rational.

Step-by-step explanation:

A rational number is any integer, fraction, terminating decimal, or repeating decimal.

It is found that 0.27322370013414... is rational number.

Natural numbers are: 1, 2, 3, ....

Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )

Rational numbers are numbers which can be written in the form of a/b where a and b are integers.

Example: 1/2, 3.5 (which is writable as 7/5) etc.

Irrational numbers are those real numbers which are not rational numbers.

Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.

Since, rational number is any integer, fraction, terminating decimal, or repeating decimal.

Thus, 0.27322370013414... is rational number.

Answer:

She can make almost 1 phone call in an hour (particularly, 46 minutes of call per hour)

Step-by-step explanation:

This problem can be solved by using ratios and proportions.

Step 1: Identify the "knowns" from the "unknown."

It is known that Daisy can make 6 phone calls in 13 hours. Now, the problem is asking for the number of phone calls Daisy can make in 1 hour.

The "unknown" here is the number of phone calls Daisy can make in 1 hour.

Step 2: The values should be plug into the proportion.

             [tex]\frac{6 phone calls}{13 hours}[/tex] = [tex]\frac{x phone calls}{1 hour}[/tex]

Step 3: We can now solve the proportion.

[tex]\frac{6}{13}[/tex] = [tex]\frac{x}{1}[/tex] ⇒x = 0.46 calls per hour (almost 1 call per hour)

Step-by-step explanation:

Step-by-step explanation:

Hey there!

Given;

Slope (m) = -3/5

And passes through the point(4,-4).

Now; The equation of a line in slope intercept form is y= mx+b.

So, try to bring it in y= mx+b form.

Firstly let's use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

Now, keep all values.

[tex](y + 4) = \frac{ - 3}{5} (x - 4)[/tex]

Now, simplify to get answer.

[tex]5(y + 4) = - 3(x - 4)[/tex]

[tex]5y + 20 = - 3x + 12[/tex]

[tex]5y = - 3x + 12 - 20[/tex]

[tex]5y = - 3x - 8[/tex]

[tex]y = \frac{ - 3}{5} x - \frac{8}{5} [/tex]

Therefore the equation is y = -3/5x - 8/5.

Hope it helps...

Answer:

The value of x = 12

Step-by-step explanation:

Here, we are to find the value of x

If the two angles are supplementary, it means that they add up to be 90 degrees

Thus;

∠GHJ + ∠MHJ = 90

6x + 18 = 90

6x = 90-18

6x = 72

x = 72/6

x = 12

Answer:  x=-5  x=2

Step-by-step explanation:

x^2+5x-2x-10=0  factor out x from the expression

Xx(x+5)-2x-10=0   factor out x+5 from the expression

(x+5)x(x-2)=0 when the product of factors equals 0, at least one factor is 0

x+5=0   solve for the equation x

x-2=0

       x=-5

      x=2

Answer:

$46.50 = $15+ $5.25x

it will take her 6 weeks

Step-by-step explanation:

she has $15, so that stays the same and the amount she saves each week is multiplied by the number of weeks. then solve the equation to find the value of x or the number of weeks and get 6 weeks

Answer:

6 weeks

Step-by-step explanation:

5.25 times 6 equals 31.5 plus 15 equals 46.50

Answer:

Slope = -2/7; Y intercept = +2

Step-by-step explanation:

First, for this particular question - we want to convert the equation to slope intercept form! You may recognize it already, it looks like this:

y = mx + b

Here's how:

[tex]2x+7y=14\\2x+7y - 2x = -2x+14\\7y=-2x+14\\\frac{7y}{7} =\frac{-2x+14}{7} \\y = \frac{-2}{7}x+2[/tex]

The above shows this equation in slope intercept form: y = -2/7x + 2.

The slope of this line is -2/7 while the y intercept is 2!

*Note*: In the slope-intercept formula, m stands for the slope, and the b is the intercept!

Hope I was of assistance! Algebra can be a little difficult but you'll get it! Have a nice day and spread the love! <3
