Answer:

(9x, 9y) dilation

Step-by-step explanation:

(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

Answer:

Step-by-step explanation:

The steps are more or less the same, except for one new addition:

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat.

16x0.2=3.2

16+3.2=19.2

So the price is $19.20

Answer:

no real solutions

Step-by-step explanation:

- Rewrite equations:

y=3x−11;−3x+y=−13

Step: Solvey=3x−11 for y:

y=3x−11

Step: Substitute 3x−11 for y in−3x+y=−13:

−3x+y=−13

−3x+3x−11=−13

−11=−13(Simplify both sides of the equation)

−11+11=−13+11(Add 11 to both sides)

0=−2

Answer:

No solutions.

Answer:

x = 11

Step-by-step explanation:

The given angles are corresponding angles and are congruent, then

12x - 9 = 10x + 13 ( subtract 10x from both sides )

2x - 9 = 13 ( add 9 to both sides )

2x = 22 ( divide both sides by 2 )

x = 11

We would expect that 4 of the next 9 children to enroll will be elementary school students.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If 8 out of the last 18 children to enroll at the daycare center were elementary school students,

We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:

= 8/18

= 4/9

This means that 4 out of every 9 children enrolled were elementary school students.

If we want to predict how many of the next 9 children to enroll will be elementary school students,

We can use this ratio:

4/9 of 9 children

= (4/9) x 9

= 4

Therefore,

We would expect that 4 of the next 9 children to enroll will be elementary school students.

Answer:

138

Step-by-step explanation:

First, we can simply replace the variables with their numerical values.

Whenever you see a number with a letter (variable) in front of it, this means to multiply.

c=5 and d=4

6 × 5^2 - 5 × 4 + 8

Since there are multiple operations in this expression, we must use PEMDAS.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Now, we can apply the operations.

There are no parenthesis.

In this expression, exponents are present.

6 × 5^2 - 5 × 4 + 8

6 × 25 - 5 × 4 + 8

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There is multiplication.

6 × 25 - 5 × 4 + 8

150 - 5 × 4 + 8

150 - 20 + 8

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There is subtraction.

150 - 20 + 8

130 + 8

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

There is addition.

130 + 8

158

Therefore, 6 × 5^2 - 5 × 4 + 8 = 138.

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.

Addition and subtraction of two matrices can be done if they have the same dimensions.  This is done by simply adding or subtracting the corresponding entries in matrices.

Given:

A right triangle with legs 5 units and 6 units.

To find:

The measure of angle opposite of side whose length is 5 units.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

Let [tex]\theta [/tex] be the missing angle. Then, for the given triangle,

[tex]\tan \theta=\dfrac{5}{6}[/tex]

[tex]\theta=\tan^{-1}\dfrac{5}{6}[/tex]

[tex]\theta=39.805571^\circ[/tex]

Round the value to the nearest degree.

[tex]\theta\approx 40^\circ[/tex]

Therefore, the measure of the required angle is 40 degrees.

Answer:

The scale factor is 1/3

Step-by-step explanation:

Here, we want to get the scale factor used in dilating the original segment

As we can see;

(9,3) turned to (3,1)

looking at this , we can see that both coordinate values were divided by 3

So what this mean is that the particular scale factor used is reduction by 1/3

This is the case with the other point as (-6,-9) turned to (-2,-3)

Answer:

1. 60 is his y-intercept

2. $82.11 in his account after 8 years

Answer:

The y-intercept of Jacob's graph is $60, which represents the initial amount of money he deposited into the account.

If Jacob doesn't deposit any additional money into the account, the amount of money he will have in eight years can be found by plugging in x=8 into the equation y = 60(1 + 0.04)^x and evaluating:

y = 60(1 + 0.04)^8

y ≈ $82.08

So the answer to the second question is that Jacob will have approximately $82.08 in the account after eight years, assuming he doesn't deposit any additional money into the account.

If the width of the rectangular painting is one unit then the height of the painting will be 3/8 yards. Then the correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A painting is going to be reprinted as a poster.

The dimensions of the painting are 3/4 of a yard and 1/2 of a yard wide.
