If the value of the scale factor is 2.5 then the coordinates of point C of the image of the triangle after dilation is (12.5, 5).

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

△ABC has vertices A(2, 2), B(3, 4), and C(5, 2).

Then the coordinates of point C of the image of the triangle after a dilation centered at the origin with a scale factor of 2.5.

Then the dilated point C' will be given as

C' = Scale factor × C

C' = (2.5 × 5, 2.5 × 2)

C' = (12.5, 5)

Step-by-step explanation:

Algebra (from Arabic: الجبر‎, romanized: al-jabr, lit. 'reunion of broken parts,[1] bonesetting[2]') is one of the broad areas of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols;[3] it is a unifying thread of almost all of mathematics.[4] It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics. Abstract algebra is a major area in advanced mathematics, studied primarily by professional mathematicians.

Elementary algebra differs from arithmetic in the use of abstractions, such as using letters to stand for numbers that are either unknown or allowed to take on many values.[5] For example, in {\displaystyle x+2=5}x+2=5 the letter {\displaystyle x}x is an unknown, but applying additive inverses can reveal its value: {\displaystyle x=3}x=3. Algebra gives methods for writing formulas and solving equations that are much clearer and easier than the older method of writing everything out in words.

The word algebra is also used in certain specialized ways. A special kind of mathematical object in abstract algebra is called an "algebra", and the word is used, for example, in the phrases linear algebra and algebraic topology.

A mathematician who does research in algebra is called an algebraist.

Numeric expressions apply operations to numbers. For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression.

Answer:

<3.

Step-by-step explanation:

Algebra In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols. it is a unifying thread of almost all of mathematics. And algebraic expression includes, a variable is an x, but they could be different signs like maybe a y, q and etc. coefficient is the main number, an operation which is the sign (+, x, - or division sign). and then the constant, which are the last number and the final number.

I don't know how to explain it but as soon as you start to do it, you'll learn what algebra is! it's not that hard it's like doing a regular problem just with a variable.

Oh yeah, sorry if this out of order but sometimes in algebra you have to figure out what the x is in some problem. Khan academy could help you learn!

Answer:

The three skirts each cost $24.99

The two skirts priced $3 below the others cost $21.99

Step-by-step explanation:

Let [tex]a[/tex] represent the amount of money the "three skirts at one price" costs.

Let [tex]b[/tex] represent the amount of money the "2 skirts priced $3 below the others" costs.

From there, we can form the system of equations and solve:

[tex]3a+2b=118.95\\a-3=b\\\\3a+2(a-3)=118.95\\3a+2a-6=118.95\\5a-6=118.95\\5a=124.95\\a=24.99\\\\a-3=b\\24.99-3=b\\21.99=b\\b=21.99[/tex]

Answer:

[tex]c=85[/tex]

Step-by-step explanation:

[tex]c=180-a-b[/tex] where [tex]a=62[/tex] and [tex]b=33[/tex]

Step 1.  Substitute a for 62 and b for 33

[tex]c=180-(62)-(33)[/tex]

Step 2. Subtract [tex](180 - 62)[/tex]

[tex]c=118-33[/tex]

Step 3. Subtract (again)

[tex]c=85[/tex]

so c = 85

Answer: 170.25

Step-by-step explanation:

Quick version

Step 1: Convert 15 percent to decimal

[tex]15\%\:=\frac{15}{100}\\\\= 15 \%[/tex]

Step 2: Multiply 0.15 to 1135

[tex]0.15\cdot \:1135\\\\=170.25[/tex]

170.25 is 15 percent of 1135.

Answer:

170.25 is the solution.

Step-by-step explanation:

Let's find 15% of 1135.

Value of the percentage is,

→ 15 ÷ 100

→ 0.15

Let's find the solution,

→ 1135 × 0.15

→ 170.25

Thus, the answer is 170.25.

Answer:

12.53 = 6j + 2.51

Step-by-step explanation:

Since there are 6 bottles, we would muitply j by 6 to end up with 6j

The price of the bag of chips, $2.51, is already added on to make up the total cost of $12.53

12.53 = 6j + 2.51

Answer:

False

Step-by-step explanation:

3(5 - 2x) = 3(2x) - 3(5)

~Simplify

15 - 6x = 6x - 15

~Reorder

15 - 6x = -15 + 6x

As you can see, they are not the same so false.

Best of Luck!

Answer:

y= [tex]-\frac{4x}{9}[/tex] + [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

6=4x+9y

First swap sides so that all variables are on the left side.

4x+9y=6

Subtract 4x from both sides.

9y=6-4x

Divide both sides by 9, this undoes the multiplication.

y=[tex]\frac{6-4x}{9}[/tex]

Divide 6-4x by 9.

y= [tex]-\frac{4x}{9}[/tex] + [tex]\frac{2}{3}[/tex]

Answer: -30

Step-by-step explanation:

BODMAS

let's first solve the bracket:

[tex] = {( - 2)}^{2} - 30 \div 5 \times 6 + 2 \\ = 4 - 30 \div 5 \times 6 + 2[/tex]

then let's divide:

[tex] = 4 - (30 \div 5) \times 6 + 2 \\ = 4 - 6 \times 6 + 2[/tex]

then let's multiply:

[tex] = 4 - (6 \times 6) + 2 \\ = 4 - 36 + 2[/tex]

simplify:

[tex] = - 30[/tex]
