Answer:
see explanation
Step-by-step explanation:
If 2 lines are perpendicular then the product of their slopes equals - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Consider the given equations
3x - 4y = 12 ( subtract 3x from both sides )
- 4y = - 3x + 12 ( divide terms by - 4 )
y = 
x - 3 ← in slope- intercept form
with slope m =
3y = 12 - 4x = - 4x + 12 ( divide terms by 3 )
y = - 
x + 4 ← in slope- intercept form
with slope m = -
Then
× - = - 1
Since the product of their slopes = - 1 then the lines are perpendicular
Answer:
Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n
The side opposite to 60 degree angle: 
The side opposite to 90 degree angle: 2n
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x =
Answer: $23.10
Step-by-step explanation:
18/3 = 6
3.85 x 6 = $23.10
Plug in 0 for x
0 - 6y = 30
y = -5
Y intercept: (0,-5)
Plug in 0 for y
5x = 30
X = 6
X intercept: (6,0)
Answer:
B. .002, .03, .6, .9
Step-by-step explanation:
.002 is .002
.03 is .030
.6 is .60
And, .9 is .90
So in conclusion, least to greatest would be .002 , .030 , .60 , then last but not least .90. The option that best matches this is B!
