One dimension of a rectangle is 3 more than twice the other dimension. Let x be the
shortest dimension. Write an equation for the area of the rectangle.
A= x + 2x + 3
A = x(2x + 3)
A= 3x +2
A= 2x +3
The area of the rectangle with one dimension sizes three more than twice the other dimension is A= x(2x+3)
We assume that there is rectangle ABCD with lines AB and CD are parallel with each other. Meanwhile lines BC and DA are parallel with each other. We could ssume that lines BC and DA are the shortest lines.
Please take a look at the picture below.
Based on the formula of rectangle, the area of rectangle could be calculated using the multiple between the longest line and the shortest line.
It could be written based on the rectangle we have into such formula:
A = AB × BC
A = CD × DA
A = AB × DA
A = CD × BC
If we input the rules from the question, then we could find the relationship between the shortest and the longest lines. Hence:
AB = CD = 2(BC) + 3
AB = CD = 2(DA) +3
if we assume that the shortest line is x, then we will get the formula:
BC = DA = x ...(1)
AB = CD = 2x+3 ...(2)
If we input equation (1) and (2) into the rectangle area formula, we will get the result:
A = AB × BC
A = (2x+3)

Which of the following is an example of a data set with 5 values for which the standard deviation is zero. a) -2.-1.0.1.2 b) 4.4.4.4.4 c) -5,-3.0.3.5 d) 1,2,3,4,5
The standard deviation for the dataset (4, 4, 4, 4, 4) is zero (0)
To find a data set with 5 values for which the standard deviation is zero,
⇒ (4, 4, 4, 4, 4)

due to the fact that a student ID is a primary key in a table and that (StudentID, SSN) can also combine to form a composite key that can be used to identify a record in a table in a unique way. The augmented functional dependency between the StudentID and SSN enables you to locate additional data in the table. However, using only StudentID will also assist you in finding data in the table.

which graph represents y=-2x
A graph which represents the linear function y = -2x is: graph B.
What is a graph?In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.
Generally speaking, the graph of any proportional relationship is characterized by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis (x-coordinate) either increases or decreases, the values on the y-axis (y-coordinate) increases or decreases simultaneously.
In this context, we can reasonably infer and logically deduce that the relationship between x-values and y-values in the graph of y = -2x is proportional as it passes through the origin (0, 0).

Answer:
b) [-11, 3]
Step-by-step explanation:
Given equation,
→ 3 + |t + 4| = 10
Now the value of t will be,
→ 3 + |t + 4| = 10
→ 3 + t + 4 = 10 || → 3 -(t + 4) = 10
→ t + 7 = 10 || → -t - 1 = 10
→ t = 10 - 7 || → -t = 10 + 1
→ [ t = 3 ] || → [ t = -11 ]
Hence, value of t is 3 (or) -11.
a) How many times does the line y = -6 intersect with the circle x² + y² = 36 ?
b) Hence, use a single word to describe what the line is to the circle.
Answer:
a) Once,b) Tangent.Step-by-step explanation:
Part AGeneral equation of circle:
(x - h)² + (y - k)² = r², where (h, k) is center and r- radiusComparing with the general equation we see that the circle x² + y² = 36 has:
Center at the origin,Radius of 6 units.The circle radius of 6 units, so y = - 6 has only one common point.
Part BSince there is only one common point of the circle and line, the line is tangent to the circle.

packages of each that need to be purchased so every
hot dog you buy for a picnic will have a bun?
Answer:
4 Hot dogs packages and 5 hot dog buns packages.
Step-by-step explanation:
This question seems to be regarding the LCM or the least common multiple. Least common multiple is found by figuring out the first time when both numbers, in this case 10 and 8 have the multiple. You can do this by setting up a table with the multiples of each number.
8 | 16 | 24 | 32 | 40

A wholesale food supplier charges x dollars for each bag of flour and y dollars for each bag of sugar. Bakery A purchases seven bags of flour and five bags of sugar for a total cost of $260.45. Bakery B purchases five bags of flour and three bags of sugar for a total cost of $171.35. What is the cost of each bag of flour? Each bag of sugar?
The cost of each bag of flour is $ 18.85 and the cost of each bag of $ 25.7 which a wholesale food supplier charges for each bag of flour and for each bag of sugar.
Given that:
The cost of each bag of flour = x dollars
The cost of each bag of sugar = y dollars
Bakery A purchases seven bags of flour and five bags of sugar for a total cost of $260.45.
Bakery B purchases five bags of flour and three bags of sugar for a total cost of $171.35.
Making equation from both the above statements. We get,
7x + 5y = 260.45 ...... (1)
5x + 3 y = 171.35 ....... (2)
Multiplying equation (1) by 5 and equation (2) by 7. We get the value,
35x + 25y = 1302.25 ....... (3)
35x + 21y = 1199.45 ........ (4)
Subtracting equation (4) from (3). We get,
4y = 102.80
=> y = $ 25.70
Putting the value of y in equation (1). We get,
7x + 25.70 x 5 = 260.45
7x = 260.45 - 128.5
7x = 131.95/7
=> x = $ 18.85
Hence, we can say that a wholesale food supplier charges 18.85 dollars for each bag of flour and 25.7 dollars for each bag of sugar.

Answer:
The correct answer is B
Step-by-step explanation:
I went a weird way to get this. I wrot the line in the slope intercept form and then converted it to the standare form.
For the slope intercept form I need a slope and a y interctp. I used the two points given to find the slope. The slope is the change in y over the change in x. From the points the y values are 3 and -1. The x values are 1.2 and -4
[tex]\frac{3 - -1}{\frac{1}{2}- - 4 }[/tex] = [tex]\frac{3+1}{\frac{1}{4}+4 }[/tex] = [tex]\frac{4}{\frac{9}{2} }[/tex]
4 ÷[tex]\frac{9}{2}[/tex] = [tex]\frac{4}{1}[/tex] x [tex]\frac{2}{9}[/tex] = [tex]\frac{8}{9}[/tex]
[tex]\frac{8}{9}[/tex] is the slope
Now to find the y intercept
I will use
slope [tex]\frac{8}{9}[/tex] (m)
y = -1 from the point (-4,-1) given
x = -4 from the point (-4,-1) given
y=mx + b
-1 = [tex]\frac{8}{9}[/tex](-4) + b
-1 = [tex]\frac{-32}{9}[/tex]x + b Add [tex]\frac{32}{9}[/tex] to both sides
[tex]\frac{23}{9}[/tex] = b
y = [tex]\frac{8}{9}[/tex]x + [tex]\frac{23}{9}[/tex] Multiply all the way thorugh by 9
9y = 8x + 23 Subtract 9y from both sides
0 = 8x -9y + 23 Subtract 23 from both sides
-23 = 8x -9y
or
8x -9y = -23
