We are given equations as
Firstly, we will write in slope intercept form of line
y=mx+b
Subtract both sides by 4x
now, we can divide both sides by a
we can find slope
so, we get
we are given second equation as
Firstly, we will write in slope intercept form of line
y=mx+b
divide both sides by a
we can find slope
we are given both lines are perpendicular
so, the multiplication of their slopes must be -1
we can plug values
now, we can solve for a
Multiply both sides by a
now, we can solve for a
we get
...............Answer
Answer:Put this in y= mx +b form
we have the slope(4) as well as a set of points for x and y so we have everything we need to solve for b
1= 4(2) + b
1 =8+b B=-7
so equation is y = 4x -7

Answer:
Step-by-step explanation:
Total amount of water = 500 ml
Mary drank = 400 ml
<u>Left:</u>
= 500 ml - 400 ml
= 100 ml
This was divided equally among 4 friends.
So,
<u>Each friend got:</u>
= 100 ml/4
= 25 ml
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Answer:
(-20 - 10) / (-12 - (-10))
-30 / -2
30/2
now the midpoint would be half the two points
30/2 ÷ 2/2 = 15/1
So add 15 to -20 (or subtract 15 from 10) for the y, and add 1 to -12 (or subtract 1 from -10) for the x.
1 times fee doesn't change
150 doesn't change
thtat is the 1 times fe
service fee per month
55 times x=other part
x=number of months
55x=monthly fee part
y=total cost
