Answer:

neither

Step-by-step explanation:

find the slopes of FG and HJ using the slope formula (y_2-y_1)/(x_2-x_1)

FG: (-1+3)/(-2-1)=2/-3=-2/3

HJ: (3-0)/(6-5)=3/1=3

perpendicular lines have slopes that are the negative reciprocal of each other. -2/3's negative reciprocal is 3/2 which isn't 3. the lines aren't parallel or perpendicular

Distance between 2,-5 and 3,-7

joja [24]

Answer:

√5

Step-by-step explanation:

$(2 ,-5) = (x_1,y_1)\\(3,-7)=(x_2,y_2)\\\\d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\ \\d = \sqrt{(3-2)^2 +(-7-(-5))^2}\\ \\d = \sqrt{(1)^2+(-7+5)^2}\\ \\d = \sqrt{(1)^2 + (-2)^2}\\ \\d = \sqrt{1 +4}\\ \\d = \sqrt{5}$

2x + 6y= 8 4x + 12y = 16

Korolek [52]

Answer:

x=0 , y=0

Step-by-step explanation:

2x +6y= 8 .....eqn 1

4x +12y= 16....eqn2

we multiply eqn 1 by 2.. because we want at least one variable to have the same coefficient so we can simply.

2x +6y =8... ×2

will give you 4x +12y = 16....eqn 3

so now we subtract eqn 2 from eqn 3

4x + 12y= 16

- 4x + 12y = 16

_____________

0 + 0 = 0

therefore x = 0 and y= 0

Find the missing terms in the arithmetic sequences a). -45, _ , _ , _, -39 b) -34,_,_,77

ANTONII [103]

Answer:

a) -45, -43.5, -42, -40.5, -39. f(n) = -45 + 1.5(n-1)

b) -34, 3, 40, 77. f(n) = -34 + 37(n-1)

Step-by-step explanation:

The explicit formula for an arithmetic formula can be defined as: f(n) = f(1) + d(n-1).

Where n is the number, and d is the common difference.
