The scale factor used to create the dilated Triangle M'S'V is 2/3.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the increase or decrease in the size of a figure by a factor k. If k > 1, it is an increment whereas if k < 1, it is a decrease.

Triangle MSV has vertex at M(-3, 3) while that of M'S'V' has vertex at M'(-2, 2). Hence the scale factor is 2/3

The scale factor used to create the dilated Triangle M'S'V is 2/3.

Answer:

Correct answer is C

Step-by-step explanation:

The blue graph is translated down 3 which would give you the minus 3 and translated left 4 giving you the plus 4..

The equation of the blue graph is G ( x ) = ( x + 4 )² - 3

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the equation of the graph be represented as A

Now , the value of A is

Since the graph is that of a parabolic curve ,

It is a quadratic equation of the form y = ( x + a )² - b

And , the graph is shifted right to 4 units and down by 3 units

So , the equation of graph is G ( x ) = ( x + 4 )² - 3

Hence , the equation of graph is G ( x ) = ( x + 4 )² - 3 and plotted

Answer:

200

Step-by-step explanation:

11^2+10^2=x^2

121+100=x^2

221=x

nearest 100th would be 200

The perimeter of an object is the sum of all sides.

a book is a rectangle which has 4 sides. 2 sides would be the length and 2 sides would be the width.

Set up the equation:
70 = 20 + 20 + x + x

Simplify

70 = 40 + 2x

Subtract 40 from both sides

30 = 2x

Divide both sides by 2

X = 15

Apply BPT theorem or Thales theorem

So

And

Option A

Charlene’s new net income will be $113.70.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the monthly salary of Charlene is $3,410. While her net income is 7% of her monthly income. Therefore, the net income of the Charlene is

[tex]7\%\ of\ \$3410 = \text{Charlene Net income}\\\\\dfrac{7}{100} \times 3410 = \text{Charlene Net income}\\\\ \text{Charlene Net income} = \$238.7[/tex]

Thus, Charlene's net income is $238.7.

Now since Charlene is going to reduce her net income by $125 each month, therefore,

Charlene New Net Income = Charlene Net Income - $125

                                              = $238.7 - $125

                                              = $113.70

Hence, Charlene’s new net income will be $113.70.

Answer:

Since rational numbers can be written as a ratio, such as a/b, then irrational numbers can not be written that way.

Step-by-step explanation:

Square roots of non-perfect squares are irrational numbers because they are non-terminating and non repeating decimals

When solving a quadratic equation by completing the square, the b value should be even so as not to have fractions.

A polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Polynomial are classified based on degree as linear, cubic, quadratic etc.

Answer: Choice B

Explanation:

Convert each percentage mentioned to decimal form. Example: 3% = 0.03

Then multiply each time value with the decimal form of the interest rate.

Choice B yields the smallest result, so it will lead to the lowest amount of interest to pay on top of the principal. Therefore, option B is the best route to have the lowest total repayment.

Answer:

(3, 0)

Step-by-step explanation:

So with the 2 equations you can either choose which to start with but you need to make the X or Y the opposite from the other equation.

1.

3x + y = 9 (keep as is)
x + 2y = 3 --> -3( x + 2y = 3) In this case I chose to make the X the opposite of each other

--

3x - 3x = 0 (forced to get rid of)

y - 6y = -5y (Get the -6 by -3 x 2)

9 - 9 (Get the -9 by -3 x 3)

Left with:

-5y = 0 (Divide both sides by -5 to get X alone)

y = 0

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

(Choose any ORIGINAL equation)

x + 2y = 3

x + 2(0) = 3 (substitute)

Left with:

x = 3  (x + 0 = 3)

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

Optional:

Chose the other equation (the opposite from above)

Substitute X and Y in 3x + y = 9

3(3) + (0) = 9

Left with: 9 = 9 (check)

So:

5x*7x= 35x^2

5x*-6= -30x

7x*2= 14x
2*-6= -12

So just add it all up, combine like terms and you have your answer.

35x^2 -16x -12

Answer:

12x - 4

Step-by-step explanation:

Add like terms.

5x + 7x = 12x

2 + (-6) = -4

Therefore, (5x + 2) + (7x - 6) = 12x - 4.

Step-by-step explanation:

The first (80%) mortgage has an interest rate of 4.75%, and the second (20%) mortgage has an interest rate of 7.525%. Both are 30-year fixed-rate mortgages.

======================================================

Explanation:

The formula we'll be using is

P = (L*i)/( 1-(1+i)^(-n) )

where,

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

For the first mortgage (80%), we need to find out the L value

L = 80% of 175,000 = 0.80*175,000 = 140,000

The monthly interest rate is the annual rate over 12

i = r/12 = 0.0475/12 which I'll keep as a fraction

Lastly, this mortgage goes for 30 years aka 30*12 = 360 months. So n = 360.

To summarize the input values we'll use, we have,

Let's compute the monthly payment

P = (L*i)/( 1-(1+i)^(-n) )

P = (140,000*0.0475/12)/( 1-(1+0.0475/12)^(-360) )

P = 730.30627110436 approximately

P = 730.31

The first mortgage has a monthly payment of $730.31

We'll use this later.

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

Now onto the second mortgage (20%)

L = 20% of 175,000 = 0.20*175,000 = 35,000

i = r/12 = 0.07525/12 which I'll keep in fraction form

n = 360 months (same as before)

In short,

So,

P = (L*i)/( 1-(1+i)^(-n) )

P = (35,000*0.07525/12)/( 1-(1+0.07525/12)^(-360) )

P = 245.32451498724 approximately

P = 245.32

The second mortgage has a monthly payment of $245.32

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

The last step is to add the two monthly payments (found at the conclusion of each previous section)

730.31 + 245.32 = 975.63

Answer:

2,340,208.5 or 2,340,209

Step-by-step explanation:

You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times.  But that would take a while.

we got 1.05 because the formula says that y = a( 1 + r ) power t

for a we will give it 1

so y = 1 ( 1 + 0.05) power t

it will give us 1.05

to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.

So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209

Answer:

no we cannot because when we solve x-2=5 it gives x=7 and x+3=5 gives x=2 if we place the x value as 7 then it does not justify (x-2)(x+3)=5, if we put x= 2 then again it does not justifies (x-2)(x+3)=5

Step-by-step explanation:

x-2=5

x=5+2

x=7

x+3=5

x=5-3=2

putting x=7 in given equation

(7-2)(7+3) is not equal to 5

putting x=2 in given equation

(2-2)(2+3) is not equal to 5

that's why we can't solve
