Give the slope-intercept form of the equation of the line that is perpendicular to –7x + 5y = 12 and contains P(–7, 4).
kherson [118]

y = - \frac{5}{7} x - 1

the equation of a line in slope-intercept form is

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

rearrange - 7x + 5y = 12 into this form

add 7x to both sides

5y = 7x + 12 ( divide all terms by 5 )

y = \frac{7}{5} x + \frac{12}{5} ← in slope- intercept form

with slope m = \frac{7}{5}

given a line with slope m then the slope of a line perpendicular to it is

perpendicular slope = - \frac{1}{m} = - \frac{5}{7}

The partial equation of the perpendicular line is

y = - \frac{5}{7} x + c

to find c substitute (- 7, 4 ) into the partial equation

4 = 5 + c ⇒ c = 4 - 5 = - 1

y = - \frac{5}{7} x - 1 ← in slope- intercept form

Which relation is a function? PLEASE HELP
Georgia [21]

Answer:

A

Step-by-step explanation:

for the relation to be a function then each value of x in the domain must map to exactly one unique value of y in the range

this is the case for A

in B : 3 → 2 and 3 → 8 ← not a function

in C : - 2 → 5 and - 2 → 7 ← not a function

in D : 2 → 2 and 2 → 3 and 3 → 3 and 3 → 2 ← not a function

A state vector X X for a four-state Markov chain is such that the system is four times as likely to be in state 2 as in 4, is no
Vesna [10]
All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.

That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If x_i is the component for state i, then you have

x_1+x_2+x_3+x_4=1\iff 0.2+4x_4+0+x_4=1\implies5x_4=0.8\implies x_4=0.16

which means x_2=4x_4=0.64. So the state vector is \mathbf x=(0.2,0.64,0,0.16).

Para hacer una ración de puré de papa se necesita 1/5 de kg. ¿Cuántas raciones se pueden hacer con 7/4 de kg?
Talja [164]

Answer:

Cantidad de raciones=  8.75 raciones

Step-by-step explanation:

Dada la siguiente información:

Para hacer una ración de puré de papa se necesita 1/5 de kg.

<u>Vamos a pasar las cantidades a décimales:</u>

Ración puré= 0.2kg

Kg de papa= 7/4= 1.75 kg

<u>Ahora, dividimos la cantidad total por la cantidad unitaria:</u>

Cantidad de raciones= 1.75/0.2

Cantidad de raciones=  8.75 raciones
