Give the coordinates of a point on the line whose equation in point-slope form is.
pantera1 [17]

Answer:

  (4, -2)

Step-by-step explanation:

The point-slope form of the equation for a line is ...

  y -k = m(x -h)

for a line with slope m through point (h, k).

Comparing this to the equation you're given, you can see that the point that was used is (h, k) = (4, -2).

_____

You can find other points on the line, but this one is the easiest to find, since it can be read directly from the equation.

A lot is in the shape of a triangle. One side is 100 ft longer than the shortest side, while the third side is 700 ft longer tha
vaieri [72.5K]

We have the next information

x= the shortest side measure

y= the second side measure

y=x+100

z= the third side measures

z=x+700

We know also that the perimeter is 2900 ft

Therefore the equation for the perimeter of the triangle will be

P=x+y+z2900=x+x+100+x+700

we sum like terms

2900=3x+800

then we isolate the x

3x=2900-8003x=2100x=\frac{2100}{3}=700

therefore

x=700ft

y=700+100=800ft

z=700+700=1400ft

The lengths of the sides of the lote are 700 ,800, and 1400 ft,

Somebody help me!
tiny-mole [99]

Answer:

josh vendió 17 libros recaudando 306 dolares .

jessica vendió  255 libros recaudando 4590 dolares.

Step-by-step explanation:

Sustituimos por variables :

libros que vendió Jessica = x

libros que vendió Josh = y

entonces:

x + y = 272

Jessica vendió 15 veces mas libros que josh:

x = 15y

Reemplazamos en la anteriior ecuacion:

15y +y = 272

16y = 272

y = 17

Reemplazamos en la primela ecuacion :

x + 17 = 272

x = 255
