An equation parallel and perpendicular to 4x+5y=19

UNO [17]

Answer:

Parallel line:

$y=-\frac{4}{5}x+\frac{9}{5}$

Perpendicular line:

$y=\frac{5}{4}x-\frac{1}{2}$

Step-by-step explanation:

we are given equation 4x+5y=19

Firstly, we will solve for y

$4x+5y=19$

we can change it into y=mx+b form

$5y=-4x+19$

$y=-\frac{4}{5}x+\frac{19}{5}$

so,

$m=-\frac{4}{5}$

Parallel line:

we know that slope of two parallel lines are always same

so,

$m'=-\frac{4}{5}$

Let's assume parallel line passes through (1,1)

now, we can find equation of line

$y-y_1=m'(x-x_1)$

we can plug values

$y-1=-\frac{4}{5}(x-1)$

now, we can solve for y

$y=-\frac{4}{5}x+\frac{9}{5}$

Perpendicular line:

we know that slope of perpendicular line is -1/m

so, we get slope as

$m'=\frac{5}{4}$

Let's assume perpendicular line passes through (2,2)

now, we can find equation of line

$y-y_1=m'(x-x_1)$

we can plug values

$y-2=\frac{5}{4}(x-2)$

now, we can solve for y

$y=\frac{5}{4}x-\frac{1}{2}$

Fins the missing fraction <br> 5/2-??=1/3

oksian1 [2.3K]

Answer:

13/6 is the missing fraction

Step-by-step explanation:

well consider the missing integer as x

then 5/2 -x=1/3

so, -x=1/3 -5/2

-x = -13/6

x= 13/6

A colony of amoebas is being studied. The mass of the colony triples every day. On Day x of the study, the colony has a mass of

Gwar [14]

Answer:

mass on day 1: 3

mass on day 2: 9

mass on day 3: 27

Step-by-step explanation:

using this equation, y = 3^x, you can plug in 1, 2, and 3 for 'x' to get the value of 'y' (which represents the mass on specific days)

3^1 = 3

3^2 = 9

3^3 = 27

Answer:

55, 65, 60

Step-by-step explanation:

180-125= 55

180-115=65

65+55= 120

180-120= 60
