HELP!! Identify the transformation from ABC to A'B'C'.
1. Reflection over the y-axis
2. 90 degree rotation
3. 270 degree rotation
4. Reflection over the x-axis

Answers

Answer:

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

Choice 1.

Step-by-step explanation:

Reflection over the x-axis

Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).

The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)

Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.

work out the value of x :)

Answers

Answer:

x=67.5

Step-by-step explanation:

A full circle is 360°, and the right angle is 90°. The rest of the angle is 270°, or 4x (from 3x+x).

4x = 270

x=67.5

Find angle E and F please

Answers

Answer:D 120 degrees, F 60 degrees

Step-by-step explanation:

it is a parallelogram which means the 2 angles add up to 180 degrees. 5x+2x+12=180. Then solve, 7x=168, x=24. Then Substitute back into the angles. E is 5*24 which is 120. F is same as D which is 2x+12=60. Hope this helped

Answer:

Angle F = 60

Angle E = 120

Step-by-step explanation:

Angle E = Angle G whereas Angle D = Angle F

Angle D + Angle G = 180, Angle E + Angle F = 180

Angle D + Angle E + Angle F + Angle G = 360

In this case, it's Angle E and F. Keep in mind that Angle D is the same as Angle F so you can just do 5x + 2x+12 = 180.

Subtract 12 on both sides to get 168, so the equation is  5x + 2x = 168.

Add 5x and 2x to get 7x. Your final equation is 7x = 168

Divide 7 on both sides to get 24.

So x = 24

Now plug in x in for both angle equations so Angle F = 2(24) + 12 and you get 60.

For Angle E you plug in 5(24) and you get 120.

MODELING REAL LIFE The table shows the profit y for recycling x pounds of aluminum. Find the profit for recycling 75 pounds of aluminum. Aluminum (lb), x 10 20 30 40 Profit, y $4.50 $9.00 $13.50 $18.00​

Answers

Answer: 33.75

Step-by-step explanation:

It’s right

There is a profit of $33.75 for recycling 75 pounds of aluminum.

What is Function?

A function is a relation from a set to another set such that element in the first set only maps to one element in the other set.

A function f from a set A to a set B can be represented as f : A → B

We have,

Profit for recycling 10 lb Aluminum = 10/10 × 4.5 = 4.50

Profit for recycling 20 lb Aluminum = 20/10 × 4.5 = 9.00

and so on

Therefore, we can write this as a function.

f(x) = [tex]\frac{x}{10}[/tex] × 4.5

We have to find the profit for recycling 75 pounds of aluminum.

f(75) =  [tex]\frac{75}{10}[/tex] × 4.5

       = 7.5 × 4.5

       = 33.75

Hence the profit for recycling 75 pounds of aluminum is $33.75.
