Answer:
lines are perpendicular
Step-by-step explanation:
• Parallel lines have equal slopes
• The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange the given equations into this form and extract the slope
3x - 2y = - 6 ( subtract 3x from both sides )
- 2y = - 3x - 6 ( divide through by - 2 )
y = x + 3 ← in slope- intercept form
with slope m =
----------------------------------
4x + 6y = 2 ( subtract 4x from both sides )
6y = - 4x + 2 ( divide through by 6 )
y = - x + , that is
y = - x + ← in slope- intercept form
with slope m = -
--------------------------------------
≠ - , then lines are not parallel
× - = - 1
Thus the lines are perpendicular to each other
Answer:
A) p=12
B)p=1
C)
Step-by-step explanation:
a)
2/3(90)=5p
60=5p
5p=60
p=60/5
p=12
b)
14p-17=-3
14p=-3+17
14p=14
p=1
c)
2p+4=3/2b
2(2)+4=3/2b
4+4=3/2b
8=3/2b
3/2b=8
3b=8×2
3b=16
b=16/3
(not sure but I tried haha)
Answer:
Answer:
Step-by-step explanation:
We have to write the following expression as a power of a binomial.
The expression is .
Now, we have to rearrange the given expression.
=
= (Answer)
Since we know the identity as (a - b)³ = a³ - 3a²b + 3ab² - b³
Step-by-step explanation:
Answer:
42°
Step-by-step explanation:
Complementary angles are two angles that add up to 90°
1) 90-48 = 42
Hope this helps! :)
