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:

the slope is 5.

using Y = mx+b. you know that m will be your slope and b will be the y - intercept.

Answer:

Step-by-step explanation:

30 + .40(30) =  30(1 + .40)  = 30(1.4)  = $42

Answer:

7:4

Step-by-step explanation:

7:4 because if 13 is the total amount of games, that minus the amount of games won and tied equals the amount of games loss which is 4. Since it says wins to losses, the wins will come first in the ratio. Therefore the correct answer would be 7:4.

Answer:

7:4

Step-by-step explanation:

Answer:

y = 25x + 40

Step-by-step explanation:

Using the formula, y = mx + b we can find out what this equation would be.

m = the rate of change/slope

b = the y- intercept

25 per month is telling us that this is the rate of change.

Since the $40 is only paid once, you can tell that this is the y intercept.

The equation will look like:

y = 25x + 40

On a graph it would look like:

Let the total cost of a gym membership be y, with the number of months as x.

The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).

y = 40 + 25x

Answer:$9.5

Step-by-step explanation:

Answer/Step-by-step explanation:

✅m<1 = 90° (right angle)

✅m<2 = 90° (<1 and <2 are supplementary, and also linear pair)

✅m<3 = 90° (<1 and <3 are supplementary, and also linear pair)

✅m<4 = 115° (vertical angles theorem)

✅m<5 + m<4 = 180° (linear pair)

m<5 + 115° = 180° (substitution)

Subtract 115 from each side

m<5 = 180 - 115

m<5 = 65°

✅m<6 = m<5 (vertical angles are congruent)

m<6 = 65° (substitution)

✅m<7 = m<1 + m<6 (exterior angle theorem)

m<7 = 90° + 65° (substitution)

m<7 = 155°

✅m<8 = 180 - m<7 (linear pair theorem)

m<8 = 180 - 155 (substitution)

m<8 = 25°

✅m<9 = m<7 (vertical angles are congruent)

m<9 = 155° (substitution)

Answer:

Step-by-step explanation:

50 an hour for 2 hours. 50(2) is 100

plus the 99 consultation fee.

Assuming there's no taxes because you're one of the lucky ones that doesn't have to pay, the total charge would be $199 dollars

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.

Step-by-step explanation:

You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y

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
