Carlos performed a transformation on trapezoid EFGH to create E′F′G′H′, as shown in the figure below: A four quadrant coordinate grid is drawn. Trapezoid EFGH with coordinates are drawn at E negative 6, negative 4. F is at negative 4, negative 4. G is at negative 2, negative 6. H is at negative 7, negative 7. Trapezoid E prime F prime G prime H prime with coordinates are drawn at E prime negative 4, 6. F prime is at negative 4, 4. G prime is at negative 6, 2. H prime is at negative 7, 7.

What transformation did Carlos perform to create E′F′G′H′?

Rotation of 270° clockwise about the origin
Reflection across the x-axis
Rotation of 90° clockwise about the origin
Reflection across the line of symmetry of the figure

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

the answer should be a. snail
