108=-12 - 4 (-5n+7)I need help
Andrei [34K]

108 = -12 + -4(-5n + 7)

108 = -12 + (7 * -4 + -5n * -4)

108 = -12 + (-28 + 20n)

108 = -40 + 20n

-20n = -40 + -108

-20n = -148

n = 7.4

PLEASE HELP ME WITH ALL ITS DUE TODAY!!
Vadim26 [7]

Answer:

Line 1 Slope: - 4/3

Line 2 Slope: 3/4

Line 3 Slope: 3/4

---------------------------------------------------------------------------------------------------------------

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

Step-by-step explanation:

Line 1: Passes through (6, -4) and (0, 4).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(4 - (-4)) / (0 - 6)    

(4 + 4) / (-6)  

8 / -6

-4 / 3  

Slope = - 4/3

___________________________________________________________

Line 2: Passes through (-4, -2) and (8, 7).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(7 - (-2)) / (8 - (-4))    

(7 + 2) / (12)  

9 / 12

3 / 4  

Slope = 3/4

___________________________________________________________

Line 3: Passes through (-4, -5) and (4, 1).

We first find the slope by using this equation (y2 - y1) / (x2 - x1) -    

(1 - (-5)) / (4 - (-4))    

(1 + 5) / (4 + 4)  

6 / 8

3 / 4  

Slope = 3/4

___________________________________________________________

Line 1 and Line 2: Perpendicular

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Parallel

HELP FAST In triangle A B C, the right angle is at vertex C, a = 525 cm , b = 700 cm and c = 875 cm. What is the value of sine A
Tresset [83]

Answer:

0.6.

Step-by-step explanation:

If the right angle is < C the hypotenuse is c. The opposite side to angle A is a.

So sin A =  a / c

= 525 / 875

= 0.6.
