Answer:
Y=6X+4
Step-by-step explanation:
Para este ejercicio solo disponemos de dos datos conocidos que son la pendiente que es 6 y un punto de la recta (0,4)
Para hallar la ecuación de la recta usaremos la conocida ecuacion punto pendiente:
Y-Yo=m(X-Xo)
Donde Xo y Yo son respectivamente las coordenadas del punto dado (0,4)
Xo=0
Yo=4
m=6----> m es la pendiente
Entonces remplazamos
Y-4=6(X-0)------>Remplazamos los valores dados
Y-4=6X-0-------->Destruimos los parentesisi aplicando distributiva
Y=6X+4 ----------->Finalmente despejamos el 4 que acompaña a la Y
Answer:
<h3>25m</h3>
Step-by-step explanation:
Perimeter of the rectangular pasture P = 2(L+W)
Area A = LW
L is the length
W is the width
Given
Perimeter = 110m
Area = 750m
If the length of the pasture is 40m longer than the width, then L = W+40
110 = 2L+2w
55 = L+W .....1
750 = LW.....2
Solving simultaneously
from 1; L = 55-W
substitute into 2;
750 = (55-W)W
750 = 55W-W²
-W²+55W -750 = 0
W²-55W+750 = 0
(W²-25W)-(30W+750) = 0
W(W-25)-30(W-25) = 0
(W-25)(W-30) = 0
W-25 = 0 and W-30 = 0
w = 25m and 30m
Since L = 55-W
L = 55-25 = 30m and;
L = 55-30 = 25m
Since we are told that length id longer than the width then, the width we are going to use is 25m
