Y= 1/3x-9
notka56 [123]

Answer:

y=3x+28

Step-by-step explanation:

so a line perpendicular to one with a slope of 1/3 would have a slope of 3/1 which is just 3

so your line would be y=3x+b

to find b you just plug in the coordinates of the point that you want it to pass through into x and y. Remember that points are written as (x,y)

10=3x-6+b

10=-18+b

28= b

the equation is y=3x+28

what is the equation of the line in slope oterceptform that passes through the point(2,-1) and is parallell to the line represen
Allisa [31]

y = 2x - 5

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x - y = 6 into this form ( subtract 2x from both sides )

- y = - 2x + 6 ( multiply through by - 1 )

y = 2x - 6 ← in slope -intercept form with slope m = 2

Parallel lines have equal slopes

the partial equation is y = 2x + c

to find c substitute (2, - 1 ) into the partial equation

- 1 = 4 + c ⇒ c = - 1 - 4 = - 5

y = 2x - 5 ← equation of parallel line

A cylindrical water towers has a diameter of 15 meters and a height of 5 meters. About how many gallons of water can the gallon
Artemon [7]

Answer:

233445.54 gallons

Step-by-step explanation:

Given data

Diameter= 15m

Radius= 7.5m

Height= 5m

Let us first find the volume

the volume of a cylinder is given as

V= πr^2h

substitute

V= 3.142*7.5^2*5

V= 3.142*56.25*5

V=883.6875 m^3

Hence the volume in gallons is

233445.54 gallons  (from conversion tables)
