Describe the location of the point having the following coordinates. abscissa and ordinate have the same sign

Answers

Abscissa and ordinate have the same sign. Therefore the point will have coordinates: ( x, y ) or ( - x, - y ), Quadrant I or Quadrant III. In Quadrant II coordinates are ( - x, y ) and in Quadrant IV coordinates are ( x, - y ).
Answer:
B ) Quadrant I andQuadrant III.

Using the coordinates of two points (84, 80) and (74, 65), determine the slope of the line of best fit.a. The slope of the line is 1.5.
b. The slope of the line is 15.
c. The slope of the line is -10.
d. The slope of the line is -15

Answers

Answer:

a.the slope of the line is 1.5

Step-by-step explanation:

Hello

if two points of a line are known(P1 and P2), it is possible to find the slope of the line, the slope of a line is given by:

$slope=(y_(2)-y_(1))/(x_(2)-x_(1)) \nm=(y_(2)-y_(1))/(x_(2)-x_(1))\n$

$P1=(x_(1) ,y_(1)) \nP2=(x_(2) ,y_(2))$

Step 1

define

$P1=(84,80) , x_(1)=84 ,y_(1)=80\nP2=(74,65) , x_(2)=74 ,y_(2)=65$

Step 2

put the values into the equation

$m=(y_(2)-y_(1))/(x_(2)-x_(1))\nm=(65-80 )/(74-84)\nm=(-15)/(-10)\n m=(15)/(10)=(3)/(2)=1.5$

the slope=1.5

I hope it helps, have a great day

the slope of the line is 1.5

Julián invito a sus amigos a comer una pizza. Él comió 2/8 del total. Juan comió el doble que Julián y mica comió la mitad de lo que comió juan. a- ¿Cuántas porciones tenía la pizza? b- ¿Cuántas comió Julián? c- ¿Cuántas comió juan? d- ¿y Mica? e- ¿Cuántas porciones sobraron? f- Demuestra con un gráfico tus respuestas.

Answers

Answer:

a) La pizza tenía 8 porciones.

b) Julián comió 2 porciones.

c) Juan comió 4 porciones.

d) Mica comió 2 porciones.

e) No sobraron porciones.

f) Véase la imagen adjunta para mayor detalle.

Step-by-step explanation:

Sean $x$ , $y$ , $z$ las razones de consumo de Julián, Mica y Juan, de acuerdo con una lectura cuidadosa del enunciado tenemos que:

$x+y+z=1$ (1)

(i)Julián comió 2/8 del total:

$x = (2)/(8)$ (2)

(ii)Juan comió el doble que Julián:

$z = 2\cdot x$ (3)

(iii)Mica comió la mitad de lo que comió Juan:

$y = (1)/(2)\cdot z$ (4)

Al aplicar (2) en (3), tenemos que Juan comió:

$z = (4)/(8)$

Y ahora se aplica el resultado anterior a (4):

$y = (1)/(2)\cdot (4)/(8)$

$y = (2)/(8)$

a) El total de porciones queda representado en el denominador de las fracciones calculadas. Por tanto, la pizza tenía 8 porciones.

b) El número de porciones consumido por cada persona está representada por el numerador de las fracciones calculadas. Por tanto, Julián comió 2 porciones.

c) Juan comió 4 porciones.

d) Mica comió 2 porciones.

e) No sobraron porciones en tanto que la suma de porciones consumidas de las tres personas es igual al valor del denominador.

f) A continuación, anexamos el gráfico correspondiente que sustenta todos los cálculos matemáticos hechos en puntos anteriores.

Solve the differential equation by separation of variables
x(dy/dx)=4y

Answers

get all your x one on side and y on the opposing sideso we have
xdy=4ydx
dy/y=4dx/x
integrate both sides
lny=4lnx+C
y=e^(4lnx+C)
The answer is y=cx^4
