Which algebraic rule describes the translation of ADEF to AD'E'F?

Mathematics
1 answer:
Marrrta [24]2 years ago
4 0

Answer:

B: (x, y) --> (x + 4, y - 3)

Step-by-step explanation:

the shape DEF went to the right along the x axis wich <em>increased</em> x and then went down the y axis or <em>decreased </em>y to make D'E'F'

some good way to remember these translations and orders are...
 - x is first when plotting points, then y (x, y)
 - x increases going right, and decreases going left, as well as y increasing going up, then decreasing going down

BONUS FACT:
the symbol ( ' ) is called a prime when refering to transformations and geometry ((as in D' is pronounced D prime))

Joanne was hired by a florist to make large boes for holidays wreaths each roll of ribbon has 20 yards joanne used 3 1/2 rolls o
alukav5142 [94]

Answer: Each bow needs 4.67 yards of ribbon.

Step-by-step explanation:

We know that each roll has 20 yd.

She used 3 + 1/2 rolls, then the total length used will be (3 + 1/2) times the length of each roll, this is:

(3 + 1/2)*20 yd = (6/2 + 1/2)*20yd = (7/2)*20yd = 70 yd.

With tose 70 yards of ribbon, she made 15 bows, then the length of ribbon used in each bow will be equal to the quotient between the total length used and the number of ribbons made with it, this is:

70yd/15 = 4.67 yards

Each bow needs 4.67 yards of ribbon.

Given the linear equation 2x+y=6, perform the necessary operations to put the equation into the proper general form. Include the
forsale [732]

The general form of the given equation is 2x+y-6 = 0.

<u>Step-by-step explanation</u>:

  • The given linear equation is 2x+y=6.
  • The general form of the equation is AX+BY+C=0.

where,

  • A is the co-efficient of x.
  • B is the co-efficient of y.
  • C is the constant term.

<u>From the given equation 2x+y=6, it can be determined that</u> :

The co-efficient of x is 2. It is in the form AX = 2x. Thus, no change is needed.

The co-efficient of y is 2. It is in the form BY = 1y. Thus, no change is needed.

The constant term 6 should be replaced to the left side of the equation, since the right side of the equation must be 0 always.

While moving the constant term form one side of the equation to other side, the sign changes from +ve to -ve.

Therefore, the general form is given as 2x+y-6 = 0.
