solve for y
6x + 4y = 8
subtract 6x from each side
4y = -6x+8
divide by 4 on all sides
y = -6/4 x +8/4
y = -3/2 x +2
the slope is -3/2
Answer: -3/2
The volume of a cone is computed as follows:
where r is the radius and h is the height of the cone.
The volume of a cylinder is computed as follows:
where r is the radius and h is the height of the cylinder.
Substituting with r = 1 and h = 1, the volumes are:
And the ratio of volumes is:
Substituting with r = 2 and h = 4, the volumes are:
And the ratio of volumes is:
Answer:
A.: x=-4
B.: x=4
C.: y=4
D.: y=-2
E.: y=-3/4x + 1

The ideal radius Alan must control is cm.
<h3>Define perimeter of circle.</h3>
The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The area of a circle determines the space it takes up. A circle's diameter is equal to the length of a straight line traced through its center. Usually, it is stated in terms of units like cm or m.
Given data -
Perimeter of circular plate = 10 cm
We know that perimeter of a circle is 2r
Therefore 10 = 2r
r = 5 cm
The given error Alan can make is +-1 cm.
Minimum radius is given by
2r = 10 - 1
r =
r = 5 -
Maximum radius is given by
2r = 10 + 1
r =
r = 5 +
The ideal radius Alan must control is cm.

Answer:
Step-by-step explanation:
In order to isolate the variable in this linear inequality, we need to get rid of the coefficient that multiplies it.
This can be accomplished if both sides are divided by 3.
3x /3 = 0x
12 /3 = 4
So the asnwer is x = 4 (don't forget the less than sign)
ANSWER = x < 4
