Find y when x=9 if y varies directly as x, and y=245 when x=7
Aleonysh [2.5K]
Since y varies directly as x, you know that y=245 and x=7 can be used as a proportion, 245/7.  When you multiply this proportion to 9, you get 315.  This is the value of y when x=9.  

y=315

Z=yr solve for y how is this solved
Andreyy89
To solve for y, you do not get a value as there are no values in the equation. You can however still solve, as long as you make the equation "y =". To do this, you need to get y by itself, and we can see that it is being multiplied by r. To move the r onto the other side, we therefore have to divide by r on both sides. This leaves us with y = Z/r, which is your answer.

I hope this helps!

Examine the diagram, where BD¯¯¯¯¯¯¯¯
Sidana [21]

The value of x based on the tangent-secant theorem is: <u> 19.</u>

<em><u>Recall</u></em>:

  • The secant-tangent theorem states that when a tangent and a secant meet outside a circle, the product of the secant length and it's segment outside the circle is equal to the square of the tangent segment length.

  • Applying the tangent-secant theorem or rule, we will have this equation:

AB \times EB= DB^{2}

AB = (x-7)+4 = x -3

EB = 4

  • Substitute:

(x - 3)(4) = 8^{2} \\\\4x - 12 = 64\\\\

  • Add 12 to both sides

4x = 64 +12\\\\4x = 76

  • Divide both sides by 4

x = 19

Therefore the <u>value of x is 19.</u>
