y = -
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 =
x +
← in slope- intercept form
with slope m = 
given a line with slope m then the slope of a line perpendicular to it is
perpendicular slope = -
= - 
The partial equation of the perpendicular line is
y = -
x + c
to find c substitute (- 7, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = -
x - 1 ← in slope- intercept form
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
R(t)=10t+20. This shows the first 20 pesos, and the additional 10 pesos for every hour. Hope this helps.
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

is the component for state

, then you have

which means

. So the state vector is

.
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
