Graph the compound inequality 6x+2y<12 or x-6y>6
The graph of the compound inequalities with intersection points
(2.21, -0.63) is given below.
Please see the graph attached.
What is compound inequality?A compound inequality has two inequality statements joined either by the "or" or “and.”
We have,
6x+2y<12 or x-6y>6
We can graph each inequality.
And we also need to see the intersection between the inequalities.
Let,
6x + 2y = 12____(1)
x - 6y = 6_______(2)
From (1)
x = (12 - 2y ) / 6 put in (2)
(12 - 2y) / 6 - 6y = 6
2 - 1/3y - 6y = 6
2 - 6 = (1/3)y + 6y
-4 = 19y / 3
y = -12 / 19
y = - 0.63 put in (1)
6x + 2 x (-0.63) = 12
6x = 12 + 1.26
x = 13.26 / 6
x = 2.21
The point of intersection on the graph is (2.21, -0.63).
Thus the graph of the compound inequalities with intersection points (2.21, -0.63) is given below.

Step-by-step explanation:
If x varies directly as y and when x = 5, y = 20. Find the relationship between x and y.
the relationship between x and y when x varies directly is 4 x = y.
We know that when x varies directly with y, then:
x = k y
Now, we have x = 5 and y = 20
Substituting the values in the expression, we get that:
5 = 20 k
k = 5 / 20
k = 1 / 4
So, we get the relation as:
x = 1 / 4 y
4 x = y
Therefore, the relationship between x and y when x varies directly is 4 x = y.

what is the perimeter of a regular, triangular yield sign with aside length of 15 in
45 inches s the perimeter of a regular, triangular yield sign with aside length of 15 in
What is perimeter?The perimeter of a shape is the sum of the lengths of all its edges. For example, a triangle has three edges, so its perimeter is equal to the sum of those three lengths.
The perimeter of a square can be easily calculated if one side and all other sides are given as being the same length; for example, a square with sides measuring 5 inches long has a perimeter of 20 inches because 5 x 4 = 20. By multiplying the sum of the length and width by two, one can determine a rectangle's perimeter.
We will use the simple perimeter formula as yield sign is equilateral triangle
So, 15 × 3 = 45 inches

Answer:
Area of two rooms is 357 square feet
Length of the baseboards = 89.5 ft
Step-by-step explanation:
Area and perimeter of rectangular room:Area of the room = length * width
Area of the two rooms = area of bigger room + area of smaller room
= 19 * 15 + 8 * 9
= 285 + 72
= 357 square feet
To find the length of the baseboard, we need to subtract the width of the opening (5 feet) and width of the entry (2 1/2 feet) from the perimeter of the bigger room and subtract the width of the opening (5 feet) from the perimeter of the smaller room.
Bigger room:
length = 19 ft
Width = 15 ft
Width of the entry = 2 1/2 ft = 2.5 ft
Width of the opening between two rooms = 5 ft
Perimeter of bigger room = 2l + 2w - 5 - 2.5
= 2*19 + 2*15 - 7.5
= 38 + 30 - 7.5
= 60.5 ft
Smaller room:
length = 8ft
Width = 9 ft
Width of the opening = 5 ft
Perimeter of the smaller room = 2*8 + 2*9 - 5
= 16 + 18 - 5
= 29 ft
Length of the base board = 60.5 + 29
= 89.5 ft

2(4x - 3) - 8 = 4 + 2x
Answer: x=3
Step-by-step explanation:
2(4x - 3) - 8 = 4 + 2x
8x - 6 - 8 = 4 + 2x
8x - (6 + 8) = 4 + 2x
8x - 14 = 4 + 2x
8x - 14 + 14 = 4 + 14 + 2x
8x = 18 + 2x
8x - 2x = 18 + 2x - 2x
6x = 18
6x/6=18/6
x=3
x = 3
first you want to distribute 2 to 4x and -3
8x-6 -8 = 4 +2x
then you subtract the numbers on the left side
8x-6-8
8x-14= 4 +2x
then we want to rearrange the 4 and 2x
8x - 14 = 2x+4
the add 14 to each side and move 2x to both sides
6x=18
then divide
x=3

Whitney buys two submarine sandwiches for an after-school party. One sandwich is 45 inches long and the other sandwich is 20 inches long. Whitney wants to cut servings of the same length from both sandwiches, without having any sandwich left over. What is the greatest length serving that Whitney can cut?
Answer:
5 inches
Step-by-step explanation:
Whitney wants the greatest length that is an even divisor of both 45 inches and 20 inches.
Greatest common factorThe length Whitney is looking for is called the "greatest common divisor" (GCD) or "greatest common factor" (GCF) of the two numbers 45 and 20. There are a couple of different ways this can be found.
FactoringThe prime factors of the two numbers are ...
45 = 3×3×5
20 = 2×2×5
The only factor common to the two products is 5. It is the greatest common factor.
Whitney can cut lengths of 5 inches.
Euclid's algorithmAnother way to find the GCD is to use Euclid's algorithm. That has you ...
Divide the larger number by the smaller and keep the remainder.If the remainder is not zero, replace the larger number with it and repeat.If the remainder is zero, the smaller number is the GCD.Using this algorithm, we have ...
45/20 = 2 r 5
20/5 = 4 r 0 . . . . . The GCD is 5
Whitney can cut lengths of 5 inches.

What are parallelograms?A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are of equal length, and its opposite angles are of equal measure. The congruence of opposite sides and angles is a direct result of the Euclidean parallel postulate, and neither condition can be proven without resorting to the Euclidean parallel postulate or one of its equivalent formulations.The net is made up of six parallelograms, each representing one of the box's faces.
Four rectangular faces with dimensions of 6 ft × 4 ftThe other two faces are square in shape, with side lengths of 4 feet.The area represented by the net can be used to estimate how much cardboard Jayden will need to make the box.
The calculations are as follows:
Rectangular faces: length × height = 6 ft × 4 ft = 24 ft²Square faces: side length² = (4 ft)² = 16 ft²So, our rectangles and two squares:
4 × 24 ft² + 2 × 16 ft² = 96 ft² + 32 ft² = 128 ft².Therefore, Jayden needs (C) 128 ft² cardboard to make a box.

Can someone help me with this?
Answer:
Choice A: 11
Step-by-step explanation:
We have x² - y² = 19
x² - y² = (x + y)(x-y)
So (x + y)(x-y) = 19
Since x and y are integers as per the first statement (x, y ∈ Z), we also have x + y = integer and x-y = integer
Take (x + y)(x - y) = 19
Since 19 is prime its only factors are 1 and 19
So we have two situations which can satisfy the above
Either x + y = 1 and x -y 19 or x + y = 19 and x -y = 1
1. Let's try x + y = 1 and x - y = 19
Adding both equations together gives us 2x = 20 (y-terms cancel)
==> x = 10 ==> 10 + y = 1 or y = -9
So 2x - 9 => 2(10) - (-9) = 20 + 9 = 29
This is not one of the choices so we can go on to the next case
2 Let's take x + y = 19 and x - y = 1
Adding these two equations gives us
2x = 20, x = 10 as before
Use 10 in the equation x + y = 19
==> 10 + y = 19
==> y = 19 - 10 = 9
2x - y ==> 2(10) - 9 ==> 20 - 9 = 11
So answer is choice A: 11
Find three consecutive even integers such that the square of the third is 52 more than the square of the second.
The Three consecutive numbers will be 24.5, 25.5, 26.5
We have to take three consecutive numbers. Let the first number be 'x' and the consecutive two numbers be (x + 1), and (x + 2).
It is given that the square of the third number is greater than the square of the second number by 52. We need to create an equation that represents this situation. So, we get :
=> (x + 2)² = (x + 1)² + 52
=> x² + 4x + 4 = x² + 2x + 1 + 52
=> x = 49/2 => x = 24.5
We get value of x = 24.5. Putting this value of x in consecutive numbers we get the first, second, and third numbers as 24.5, 25.5, and 26.5 respectively.
Hence, we get the three consecutive numbers: 24.5, 25.5, and 26.5

The solution of y are 1.82 and -0.22
The general expression for quadratic equation is given as :
ax² + bx + c = 0
The quadratic formula of the above equation is given as
x = -b ± √b²-4ac / 2a
According to the question we have been the expression as
5y² - 8y = 2
Converting it into general expression we get
5y² - 8y - 2 = 0
Putting the required value in above quadratic formula we get
y = -(-8) ± √(8)² - 4*5*(-2) / 2*5
y = 8 ± √64 + 40 / 10
y = 8 ± √104 / 10
y = (8 ± 10.2)/10
y = 8 + 10.2 / 10 and y = 8-10.2 / 10

Answer:
720
Step-by-step explanation:
We are looking for the difference between 2/3 and 1/2, which we know to be 120. To subtract fractions of different denominators, we need to find the common denominator (this can be found by finding the LCM of both denominators)
120 = 2/3 - 1/2 = 4/6 - 3/6
1/6 = 120
