Answer:
x = 1/2; y = 1/3
Step-by-step explanation:
2x + 3y = 2 Eq. 1
-6x + 12y = 1 Eq. 2
Eq. 1
2x + 3y = 2
2x = -3y + 2
x = -3/2 y + 1
Eq. 2
-6x + 12y = 1
De Eq. 1 sabemos que x = -3/2 y + 1
-6x + 12y = 1
-6(-3/2 y + 1) + 12y = 1
9y - 6 + 12y = 1
21y - 6 = 1
21y = 7
y = 7/21
y = 1/3
Eq. 1
2x + 3y = 2
2x + 3(1/3) = 2
2x + 1 = 2
2x = 1
x = 1/2
Respuesta: x = 1/2; y = 1/3
Width=w
length=(40-2w)/2=20-w
A=w(40-w)
A=40w-w²
A'=40-2w=0
2w=40
w=20
20x20 is the size of the pen having the greatest area. this tells us the largest rectangle for a given perimeter is a square
1 1/2 miles in feet is 7920
Answer:
Hey!
Your answer is 1 (the y-intercept is 1)
Step-by-step explanation:
x-intercept = (
−
1/
6 ,
0
)
y-intercept = (
0
,
1
)
Explanation:
Slope formula is
= r
i
s
e/
r
u
n
Since 6 is obviously 6/
1 then...
we know that the slope goes up 6 units
and right 1 unit on a graph.
Next we have to find the y-intercept of the line
of y=6x+1, you substitute x as x=0.
y
=
6
x
+
1
y
=
6
(
0
)
+
1
so then y
=
1
