Answer:

y=10/x

Step-by-step explanation:

Y=k/x

Y=2 & x=5 implies k=10

Hence, y=10/x is the desired equation of the hyperbola

...................................................................................................................................................

Answer:

The equation is  and  y = 2 , x = 5 the value of k is 10 .

Step-by-step explanation:

As given

y varies inversely with x.

Where k is the constant of proportionality .

Thus the equation for the  inverse variation .

As given

y = 2 when x = 5

Put all the values in the equation  .

k = 2 × 5

k = 10

Thus the constant of variation is 10 .

Therefore the equation is  and when y = 2 , x = 5 value of k is 10 .

Answer link

...............................................................................................................................................

Y varies inversely with x means, y=k\x where x is the constant of variation saying that 2=k\5 and gives k=10 y=10\x would be the equation for  any x

Find the values of x and y using the given​ chord, secant, and tangent lengths.
inn [45]

Answer:

x = 15.65

y = 3.5

Step-by-step explanation:

Step 1

Find the equation for x and y

Equation for x is given as

x² = 7( 7+28) ..........Equation 1

14(14 + y) = x²........ Equation 2

Solving for Equation 1

x² = 7( 7+28)

x² = 7(35)

x² = 245

x = √245

x = 15.65

From Equation 1 , x² has been determined to be 245

Therefore we substitute 245 for y in Equation 2

14(14 + y) = x²........ Equation 2

14(14 + y) = 245

196 + 14y = 245

14y = 245 - 196

14y = 49

y = 49 ÷ 14

y = 3.5

Help pleaseee!!! He didnt go over how to do it in class....
storchak [24]

Answer:

They are both linear

Step-by-step explanation:

1.

Use rise/run to find the slope of the line.

rise=21.8

run=1

therefore, the slope is 1/28. You can use that to graph the line. If the line meets the points on your table, it is linear. It does. The equation of the line would be y=21.8x.

2.

We can use the same process as before.

rise=7

run=2

Therefore, slope is 7/2. When this line is graphed it meets all the points, so it is linear.

Alteratively, you could graph the points first and then see if you get the same slope.
