5 0

Answer:

\frac{12}{5}

Step-by-step explanation:

4/5x=3/10(x+4)  / · 10

8x=3(x+4)

8x=3x+12

8x-3x=12

5x=12  /:5

x=12/5

. This relation is an inverse variation.
IrinaK [193]

Answer:

The equation that represents the relation is;

d. y = -16/x

Step-by-step explanation:

The

An inverse variation of an ordered pairs is the set of ordered pairs that is given by the relationship that as one variable in an ordered pair increases, the other decreases and vice versa

Mathematically, an inverse relation can be expressed as follows;

y ∝ 1/x

From which we have;

y = k/x, where, "k", represents the constant of proportionality

Therefore, we have;

k = y × x

The given ordered pair are;

{(-1, 16), (2, -8), (4, -4)}

Therefore, k = y × x = 16 × (-1) = -8 × 2 = -4 × 4 = -16

The given function is y = k/x = -16/x

Therefore, y = -16/x.

3x+17&lt;47<br> -6x+9&lt;25<br> Solve the inequalities and make a number line
k0ka [10]

Answer: Read below.

Step-by-step explanation:

3x+17

Let's take the first one.

3x+17

Subtract 17

3x

Divide by 3

x

---------------------------------------------------------------------------------------------

Now the second one.

-6x+9

Here's the trick. You need to divide by -6; however, there's a rule. When you multiply or divide by negative numbers, the inequality sign flips.

x>\frac{16}{-6}

x>-\frac{8}{3}

---------------------------------------------------------------------------------------------

x has to be less than 10

x has to be greater than -\frac{8}{3} or -2.66 approximately.

in the number line, make a hollow circle on -\frac{8}{3} and draw an arrow up to 10 where, again, you have to make a hollow circle. The circles have to be hollow because neither -\frac{8}{3} nor 10 are part of the answers.

Find the center-radius form of the equation of the circle described.
Kitty [74]

Answer:

Correct answer:  (x-√2)² + (y-√5)² = 3

Step-by-step explanation:

Given data: Center (x,y) = (√2,√5) and r = √3

The canonical or cartesian form of the equation of the circle is:

( x-p )² + ( y-q )² = r²  

Where p is the x coordinate of the center, q is the y coordinate of the center and r is the radius of the circle.
