Y= -1/2x-11 , 16x-8y=-8 Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
1 answer:
Answer:
perpendicular
Step-by-step explanation:
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the intercept
For the line Y= -1/2x-11
Compare
mx = -1/2x
m = -1/2
slope = -1/2
For the equation
16x-8y=-8
Divide through by 8
2x - y = -1
- y = -2x-2
y = 2x+2
Compare
mx = 2x
M = 2
Take the product of the slopes
Mm = -1/2 * 2
Mm = -1
Since the product of their slope is -1, hence the two lines are perpendicular

Answer:
s =2
Step-by-step explanation:
you need to multiply to find the answer
6 x 2=12
Then you need to replace the s with 2 and see if it fits correctly in this case it does
6x2 -4 =8
12-4=8
Answer is b because the veritable is just 1 but the 4 stays the same

Step-by-step explanation:
3x+8y=27
3x=27-8y
x=27-8y/3
4(27-8y/3) + 3y=13
36-32/3y +3y =13
36-23/3y=13
36-13=23/3y
y=3
x=1
