Answer:

y = -4x -16

Step-by-step explanation:

Line perpendicular have the slope = -1/m

Substitute the values,

8 = (-4)(-6) + c

8 = 24 + c

c = -16

Thus, the equation of the perpendicular line is y = -4x-16

Step-by-step explanation:

Given 2 intersecting chords, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

18x = 9 × 3 = 27 ( divide both sides by 18 )

x = $\frac{27}{18}$ = $\frac{3}{2}$

If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8?

Eddi Din [679]

Answer:

2/3

Step-by-step explanation:

Y varies directly as x

Y =kx

Y=6 when x = 72

First find the relationship between y and x.

i.e find the value of k

Substitute the value of x and y

6 = k *72

Make k the subject of the formula

K = 6/72

K= 1/12

:. The rlationship between x and y is

Y = 1/12x

When x is 8

Y = 1/12 * 8

Y = 8/12

Y = 2/3 and that is the answer
