The intercept can be found when all other variables are equated to zero.
x-intercept when y = 0 and z = 0: 8x + 6*0 + 3*0 = 24 gives x = 3
y-intercept when x = 0 and z = 0: 8*0 + 6y + 3*0 = 24 gives y = 4
z-intercept when x = 0 and y = 0: 8*0 + 6*0 + 3z = 24 gives z = 8

The intercepts are (3, 0, 0), (0, 4, 0), and (0, 0, 8).

Write the coordinates of the vertices after a reflection over the y-axis.
MaRussiya [10]

Answer:

J' : (8, 1)

K' : (5, 1)

L' : (3, 6)

M' : (0, 6)

Step-by-step explanation:

the rule for reflection over the y-axis is (x, y) → (-x, y)

therefore:

J' : (8, 1)

K' : (5, 1)

L' : (3, 6)

M' : (0, 6)

A new Outdoor recreation Center is being built in Erie. The perimeter of the rectangular playing field is 456 yards. The length
MAVERICK [17]

Answer:

P= 456 = 2X +2Y    (1)

And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :

X = 4Y -7

And replacing into equation (1) we got:

456= 2(4Y-7) +2Y

456 = 8Y -14 +2Y

456 = 10Y-14

Adding 14 in both sides we got:

456+14 = 10Y

And dividing 10 on both sides we got:

Y=\frac{470}{10}= 47

And then we can solve for X and we got:

X= 4*47 -7=181

Step-by-step explanation:

For this case we can set up the following notation:

X represent the lenght

Y represent the width

And since we have a rectangular playing filed the perimeter is given by:

P= 456 = 2X +2Y    (1)

And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :

X = 4Y -7

And replacing into equation (1) we got:

456= 2(4Y-7) +2Y

456 = 8Y -14 +2Y

456 = 10Y-14

Adding 14 in both sides we got:

456+14 = 10Y

And dividing 10 on both sides we got:

Y=\frac{470}{10}= 47

And then we can solve for X and we got:

X= 4*47 -7=181

m = (y2 - y1)/(x2 - x1)
m = (1 - 5)/(3 - 6)
m = (-4)/(-3)
m = 4/3

The answer is c.
