Suppose y varies directly with x and y=20 when x = 10. What is the value of y<br> when x = 30?
S_A_V [24]

Answer:

y = 60

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 20 when x = 10, then

20 = 10k ( divide both sides by 10 )

2 = k

y = 2x ← equation of variation

When x = 30, then

y = 2 × 30 = 60

Select the two binomials that are factors of this trinomial.<br> x2 - x - 12
Slav-nsk [51]

Answer:

x² - x - 12 = (x - 4)(x - 3)

Step-by-step explanation:

We have the trinomial x² - x - 12.

We have to show two binomials to be factors of this above trinomial.

For this first we have to factorize the trinomial.

Now, x² - x - 12

= x² - 4x + 3x - 12

= x(x - 4) + 3(x - 4)

= (x - 4)(x - 3)

So the binomials are (x - 4) and (x - 3) that are factors of the trinomial x² - x - 12. (Answer)

aksik [14]
Check the picture below.

notice the midpoint of the diameter segment, is just 1,9.

also, recall the radius is half the diameter, notice how long the radius is, just 4 units.

\bf \textit{equation of a circle}\\\\ &#10;(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2&#10;\qquad &#10;\begin{array}{lllll}&#10;center\ (&{{ h}},&{{ k}})\qquad &#10;radius=&{{ r}}\\&#10;&1&9&4&#10;\end{array}
