Answer:

The answer is Add -3 and 4 should be done first

Answers:

D'' = (1, -3)

E'' = (1, -1)

F'' = (3, -1)

G'' = (3, -4)

A diagram is shown below.

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

Explanation:

The center of dilation is point E, which means this point does not move when the dilation is applied. Every other point will move.

As your diagram indicates, segment DE is 4 units long. If we apply the scale factor 1/2, then D'E' will be half as long meaning D'E' = 2. So point D' is 2 units above point E at (1,3)

Point F is 4 units away from point E. The scale factor 1/2 will bring F closer to E leading to segment F'E' = 2. So we'll start at E and move 2 units to the right to land on F ' (3, 1)

From F to G is 6 units, which cuts in half to 3. So from F' to G' is 3 units telling us we start at F ' (3, 1) and go up three units to get go G ' (3, 4)

So far we have

D ' = (1, 3)

E ' = (1, 1) ... fixed point doesn't move

F ' = (3, 1)

G ' = (3, 4)

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

From here we'll apply the reflection over the x axis rule which says

[tex](x,y) \to (x, -y)[/tex]

the x coordinate stays the same, and the y coordinate flips from positive to negative (or vice versa).

Based on what was mentioned for D', E', F' and G', we get the following

D'' = (1, -3)

E'' = (1, -1) .... this point does move now

F'' = (3, -1)

G'' = (3, -4)

Points E' and E'' are in different locations because all fixed points in this reflection are along the mirror line y = 0 (aka the x axis). In other words, if E was on the x axis, then it would not move if we applied this reflection.

Check out the diagram below see a visual summary of what happened. Note how the red points moved in closer to point E (since the distances from the center E have been cut in half) compared to the blue counterparts.

Answer:$9.5

Step-by-step explanation:

Answer:

P = (8T) / V

Step-by-step explanation:

P*V=8*T*P/P multiply both sides by P

P*V=8*T because P/P=1

P = 8T/V divide both sides by V

Answer:

$9

Step-by-step explanation:

If you do 3.5*4 then you get 14. You then use the $5 gift card so you subtract 5 from 14 and get 9

using the equation, that would be f(x) = (3.5*4)-5. Using PEMDAS, you would do the parenthesis first so it would be f(x) = 14-5 which equals 9

Answer:

[tex]x=3,-7[/tex]

Step-by-step explanation:

We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]

By applying this on the quadratic equation, we get:

[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]

Which simplifies to:

[tex]x=\frac{-4\pm10}{2}[/tex]

[tex]\therefore x=3,-7[/tex]

Answer:

when a system of equation has no solution it means that both X's are 0

If it is on a graph then two lines would be parallel to each other

Step-by-step explanation:

for example

-6x +7y= -6x+12y

automatically you would add six to the negative six and you would not have any X's. so it has no solution

-6x +7y= -6x+12y

+6           +6

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

7y=12y

Hopefully you understand what no solution is

have a great day

A system of equations having no solution implies that the equations in the system cannot be solved

A system of equation is a collection of at least two equations i.e. two or more equations

A system of equation can have any of the following number of solutions

Answer:

30 Percent

Step-by-step explanation:

Use the percent change formula.

Answer:

88.493%

Step-by-step explanation:

We solve this question using z score formula.

Z score = x - μ/σ

where

x is the raw score = 120lb

μ is the population mean = 138lb

σ is the population standard deviation = 15lb

Hence,

z = 120 - 138/15

= -1.2

Probability value from Z-Table:

P(x<120) = 0.11507

P(x>120) = 1 - P(x<120)

1 - 0.11507

= 0.88493

Converting to percentage

= 0.88493 × 100

= 88.493%

The percentage of women in that country weigh more than 120 lb is 88.493%

Answer:4

Step-by-step explanation: please just trust me!

Work Shown:

x = number of hours she babysits

1 hour = 7 dollars

x hours = 7x dollars (multiply both sides by x)

She earns 7x dollars after babysitting x hours if we ignore the $10 base fee. Add on the $10 base fee to get 7x+10 dollars total.

Therefore y = 7x+10 is the equation we want.

Answer:

I thought it would be y=10x+7 because the base fee which is the starting fee is 10 and your adding 7 every hour so that would be +7.

eqn of line

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{3}{4}[/tex] and given (0, 4) ⇒ c = 4 , then

y = [tex]\frac{3}{4}[/tex] x + 4 ← equation of line

Answer:

a) The Margin of Error = 0.26

b) The 99% Confidence Interval = ( 2.84, 3.36)

Step-by-step explanation:

a) Margin of Error

The formula for Margin of Error =

z × Standard deviation/√n

From the above question

The z score for 99% confidence interval = 2.576

Standard deviation = 0.72

n = Random number of samples = 50

Margin of Error =

2.576 × 0.72/√50

= 1.85472 /√(50)

= 0.2622970178

Approximately to 2 decimal places = 0.26

b) 99% Confidence Interval

= Mean ± Margin of Error

Mean = 3.1mm

Confidence Interval = 3.1 ± 0.26

3.1 ± 0.26

= 2.84

3.1 + 0.26

= 3.36

The 99% Confidence Interval = ( 2.84, 3.36)

y=1

Answer: y =-1

Step-by-step explanation:y =-1

Last option is correct.

Step-by-step explanation:

The given equation is

In order to solve for y, we need to isolate y.

In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.

The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation
