Una recta atraviesa el punto (4,-6) Y tiene una pendiente igual a 5/4

yulyashka [42]

Answer:

y=5/4x-11

Step-by-step explanation:

tenemos un punto (4,-6) y una pendiente equal a 5/4.

usa la ecuación y=mx+b (m es la pendiente, b es el y interceptar)

porque sabemos la pendiente es 5/4, ahora mismo la ecuación es:

y=5/4x+b

en el punto, x=4, y=-6

podemos sustituir los números en la fómula para resolver b

-6=4(5/4)+b

-6=5+b

-11=b

entonces,

la ecuación de la recta es y=5/4x-11

(¡lo siento mi español no es perfecto!)

Solve for w <br>5w+9z=2z+3w

grin007 [14]

5w + 9z = 2z + 3w

2w + 9z = 2z

2w = -7z

w= -7/2z or w= -3.5z

Find the slope of the line that passes through (-66, -21) and (-67, 20)

Sphinxa [80]

The straight line is given by the equation
y=kx+b
We substitute coordinates of points
-21=-66k+b (1)
2=-67k+b (2)
We give a system of equations
Solution of this system:
(1) b=66k-21
(2) 20=-67k+66k-21
20=-k-21
k=-21-20
k=-41
b=-41*66-21=-2727
y=-41x-2727

Becky drew a scale drawing of a sign before creating it. Her scale drawing had a width of 6 inches, and the actual sign has a wi

stealth61 [152]

Answer:

$4ft *\frac{12in}{1 ft}= 48 in$

Now since we have the same units for the scale model and the real one we can find the scale factor like this:

$Scale = \frac{48 in}{6in}= 8$

And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model

Step-by-step explanation:

For this problem we know that the scale model had a widthof 6 inches. And the actual model has a width of 4ft. First we need to convert the 4ft to inches and we got:

$4ft *\frac{12in}{1 ft}= 48 in$

Now since we have the same units for the scale model and the real one we can find the scale factor like this:

$Scale = \frac{48 in}{6in}= 8$

And we can conclude that the scale factor is 1:8 and that represent that the real object is 8 times larger than the scale model
