Answer:
Step-by-step explanation:
Given the equation
4x+12y=72
The equation of a line can written as
y=mx+c
Where m is the slope
And c is the intercept on y axis
Then, we need to write the equation given in the form of equation of a line (y=mx+c), by making y subject of the formula
4x+12y=72
12y=-4x+72
Divide through by 12
y=-4x/12 + 72/12
y=-⅓x+6
Then, comparing with equation of a line shows that
m=-⅓ and c=6
So we need to get another linen that is perpendicular to this line and passes through the point (-9,6)
The slope of the line perpendicular to another line is given as
m1=-1/m2
Then, m1=-1÷-⅓
Then, the slope of the perpendicular line is 3
Then, m=3
So apply this to equation of the line
y=mx+c
Then, y=3x+c
So to know c, we will insert the point given(-9,6), x=-9 and y=6
y=3x+c
6=3(-9)+c
6=-27+c
Then, c=6+27
c=33
Then, the equation of line becomes
y=3x+33
Answer:
meters per seconds squared
Step-by-step explanation:
seconds squared cancel out and you're leftvwith just meters when
meters/seconds squared is multiplied with the seconds squared in t^2
g means gravity and
gravity is 9.8 meters per second squared

Answer:
Original price of bicycle = $864
Step-by-step explanation:
Given:
Rate of tax = 20%
Price pay by Mathew = $1,080
Find:
Original price of bicycle
Computation:
Original price of bicycle = Price pay by Mathew[1 / (1-20%)]
Original price of bicycle = 1,080[1 / (1-20%)]
Original price of bicycle = 1,080[1 / (1-0.2)]
Original price of bicycle = 1,080[1 / (0.8)]
Original price of bicycle = 1,080[1.25]
Original price of bicycle = 1,080[1.25]
Original price of bicycle = $864
70% on books which is $35. So the answer is 35 .
