Determine the slope of the lines parallel and perpendicular to -4x+3y=11
2 answers:
Answer:
parallel = 4/3
perpendicular =-3/4
Step-by-step explanation:
Solve for y
-4x+3y=11
Add 4x to each side
3y = 4x+11
Divide by 3
y = 4/3 x +11/3
This is in the form y = mx+b where m is the slope
m =4/3
The parallel line has the same slope
parallel slope is 4/3
The perpendicular line has a negative reciprocal slope
m = -(1 /4/3) = - 3/4
Answer:
and - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
- 4x + 3y = 11 ( add 4x to both sides )
3y = 4x + 11 ( divide all terms by 3 )
y =
x +
← in slope- intercept form
with slope m = 
Parallel lines have equal slopes, thus
slope of parallel line = 
Give a line with slope m then the slope of a line perpendicular to it is
= -

Answer:
Radius
Step-by-step explanation:
CB = AB/2
Since AB is the diameter, CB is a radius
A) corresponding angle theorem
Answer:
150.31
Step-by-step explanation:
First, use Order of Operation to multiply.
16.55(8) + 5.97(3)
= 132.4 + 17.91
= 150.31
The answer would be y=(x+4)^2-37
