line j is perpendicular to lines m and n. if the products of the slope of all three lines is -8, what is the slope of line j?
jeka94

Answer:

the slope of line j is -1/8, the slope of lines m and n are both 8.

Explanation step by step:

Suppose j is the slope of line j, m the slope of line m and n the slope of line n. Since:

1. line j is perpendicular of line m, so j*m= -1

2. J is perpendicular of line n, so  j*n=-1

3. m and n and parallel so m=n

As we want to know the slope of j we clear the equations presented to us in order to find it.

(1) m* n* j = -8, since n=m we have  n^{2}* j = -8.

we clear j; n^{2} * j = -8 \\ j =\frac{-8}{n^{2} }

replacing in the equation n*j = -1 we get

n*(-8/n^2) = -1. Thus n = 8. Since j = -1/n = -1/8.

Solve this system by substitution. y = 6x - 6 y = -4x - 6 *Remember to write your answer as a coordinate point (x, y).​
Lisa [10]
Answer: (0, -6)

Explanation:
6x - 6 = -4x - 6
10x = 0
x = 0
y = 6(0) - 6
y = 0 - 6
y = -6

A supplementary angle is split into 2 angles. One angle is 2x + 20°. The other angle is 40°. Solve for x and find the measuremen
IrinaVladis [17]

Answer:

x=60 and the missing angle is 140

Step-by-step explanation:

40 × 2x + 20= 180

60 + 2x =180

2x=120

x=60

2(60)+20=140
