Alecsey [184]3 years ago
3 0

Answer: To figure out if an ordered pair is a solution to an equation, you could perform a test or experiment . Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the value you get is the same as the value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Which expressions represent the difference of exactly two expressions? Choose 3 answers: Choose 3 answers: (Choice
Ket [755]

Solution

To find out which expressions represent the difference of exactly

two expressions

a) 6(x+7) - 2

This can be simplified as

6x + 42 - 2

6x + 40

Clearly this does not represent difference of the two

expressions .


b) -2j

Clearly this represents a single expression , this does not represent

a difference of 2 expression .


c) 4f - 2g

Here we have 2 different expressions 4f and 2g

Difference of these 2 expressions are 4f - 2g

Hence , this option represent difference of exactly two

expression


d) 3xyz - 10

3xtz - 10 represnts a single expression

Here we have a single expression

Therefore it does not represent difference of exactly 2

expression .

A quadrilateral has vertices a(-4 -8) b (-2, 34) c(6,12 and d (10, -30). It undergoes the transformation (x,y) to (x/2,y/2).
worty [1.4K]

Answer:

Step-by-step explanation:

scale factor:

1/2

the coordinates of the new vertices are

A (-4/2, -8/2)

A:(-2, -4)

B (-2/2, 34/2)

B: (-1, 17)

C (6/2, 12/2)

C:(3, 6)

D (10/2, -30/2)

D:(5, -15)

I guess the dilation is 2 times bigger?
