Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
The point (2,1) is rotated 90 degrees clockwise using center (0,0). What are the coodinates of the image?
Answer:
(1,-2)
Step-by-step explanation:
Rotation of Figures
When we rotate a figure 90 degrees clockwise across the origin, each point of the given figure has to be changed from (x, y) to (y, -x).
We are given the point (2,1) and it is rotated 90 degrees clockwise across the origin, thus the image has coordinates (1,-2).
The figure below shows the point and its image.

if y varies directly as the square if x. If y=27 when x=3, find x when y=81?
Answer:
x = 3[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Given y varies directly as x², then the equation relating them is
y = kx² ← k is the constant of variation
To find k use the condition y = 27 when x = 3 , then
27 = k × 3² = 9k ( divide both sides by 9 )
3 = k
y = 3x² ← equation of variation
When y = 81, then
81 = 3x² ( divide both sides by 3 )
27 = x² ( take the square root of both sides )
x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = 3[tex]\sqrt{3}[/tex]

I rly rly need this
Step-by-step explanation:
20x² = y - 24
y = 20x² + 24
For y to have the least possible value, x² have to be the least possible, which is 0.
Since -3 <= x <= 2 includes x = 0, this is allowed.
Hence least possible value of y
= 20(0)² + 24 = 24.
Answer:
24
Step-by-step explanation:
-3---> 20(-3)^2=y-24 ----> y=204
-2---> 20(-2)^2=y-24 ----> y=104
-1---> 20(-1)^2=y-24 ----> y=44
0---> 20(0)=y-24 ----> y=24
1---> 20(1)^2=y-24 ----> y=44

find the measure of BEK
Step-by-step explanation:
Angles BEC and KEC are labelled as congruent.
Therefore (6x + 24)° = 10x°, 4x = 24, x = 6.
Hence Angle BEK = (6x + 20)° + 10x°
= (16x + 24)° = 16(6) + 24 = 120°. (C)
The value of ∠BEK will be 120° so option (C) will be correct.
What is congruence?
If two figures are exactly the same in sense of their length side all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
In other meaning, if you can copy a figure then that copy and the original figure will be congruent.
Given figure has two triangles ΔCBE and ΔCKE.
The angle of (6x + 24)° is the same as (10x)° ( given congruency of angle by double line)
So,
6x + 24 = 10x
10x - 6x = 24
4x = 24
x = 6°
So,
Angle ∠BEK
∠BEK = (6x + 24) + (10x)
∠BEK = 6(6) + 24 + 10(6)
∠BEK = 120°.
Hence "The value of ∠BEK will be 120° ".

What is the approximate circumference of the circle shown below
Answer: A) 46.5 cm
Step-by-step explanation:
Circumference = 2 π r or Circumference = π d
In this case, they give us the diameter = 14.8 cm. Therefore the radius = 14.8/2 = 7.4 cm.
π ≈ 3.14.
We can use either equation above, but because the diameter was given, we will use c = πd for simplicity.
C = π d
= (3.14)(14.8)
= 46.47 cm, which rounds to 46.5 cm

Step-by-step explanation:
If a line is a perpendicular bisector of a line segment, then
The line intersects the line segment in 4 right anglesThe line intersects the line segment in the mid-point of the line segmentAny point on the line is equidistant from the endpoints of the line segmentLet us find the true statement
∵ Line AB is the perpendicular bisector of segment IK
→ By using the 1st note above
∴ AB ⊥ IK
∴ ∠IJA, ∠KJA, ∠IJB, ∠KJB are right angles
→ By using the 2nd note above
∴ J is the mid-point of IK

A mechanical pencil costs $0.50 and a ruler costs $1.00.
What is meant by cost?In calculus, a cost function is a mathematical formula used to determine how much it will cost to produce a certain number of units. The total cost formula is used to calculate the total cost by combining the variable and fixed costs of providing goods. Total cost = (average fixed cost x average variable cost) x number of units produced. A unit price is defined as a price expressed as a quantity of one, such as $25 per ticket or $0.89 per can. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio.The current answer as follows:
a. Fill in the blanks to calculate Mrs. Ortiz's purchase price. Let x denote the price of a pencil and y the price of a ruler.
$55 = 50x + 30y
b.Fill in the blanks with the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.
$45 = 30x + 30y
c. Circle the best method for solving the system:
Elimination
d. Solve the system using the method you chose.
55 = 50x + 30y - 1(45) = (30x + 30y) - 1 = -45 = -30x - 30y
55 = 50x + 30y + -45 = -30x - 30y
10 = 20x
(1/20)10 = 20x (1/20)
0.50 = x
3(55) = (50x + 30y )3 = 165 = 150x + 90y
-5 (45) = (30x + 30y) - 5 = -225 = -150x - 150y
165 = 150x + 90y + -225 = -150x - 150y
-60 = -60y
(1/-60) -60 = -60y (1/-60)
1 = y
A mechanical pencil costs $0.50 and a ruler costs $1.00.

I got three answers for alot points ok this is the first question what is : 1/2 + 3/6 =
next question: 1/3 - 1/4 =
last question: 5 2/3 - 2 1/2
Answer:
1. 1
2. 1/12
3. 3 1/6
Step-by-step explanation:
Solution for #1. First, you have to get a common denominator. Here, that would be 6. In order to give 1/2 a denominator of 6, you will need to multiply the numerator and the denominator by 3. That will give you 3/6. Add that to the other 3/6 (3/6+3/6) which equals 6/6 which can be simplified to 1.
Solution for #2. This is just like #1. First, you have to get a common denominator. Here, that would be 12. In order to give 1/3 a denominator of 12, you will need to multiply the numerator and the denominator by 4. That will give you 4/12. Then, to give 1/4 a denominator of 12, you will need to multiply the numerator and the denominator by 3. That will give you 3/12. Then, subtract (4/12-3/12). You will get an answer of 1/12.
Solution for #3. This is slightly different from the others, I has two more steps. First, you need to changed the mixed fractions into improper fractions. You will get 17/3 and 5/2. Then, you have to get a common denominator. Here, that would be 6. In order to give 17/3 a denominator of 6, you will need to multiply the numerator and the denominator by 2. That will give you 34/6. Then, to give 5/2 a denominator of 6, you will need to multiply the numerator and the denominator by 3. That will give you 15/6. After that, subtract (34/6-15/6). You should get 19/6. Finally, divide 19/6 and you should get 3R1. So, the mixed fraction version of 19/6 is 3 1/6 (I did this by using the 3 from 3R1 as the whole number and I just put the remainder of 1 over 6 as the fractional part). You can multiply to check your answer.
