Anni [7]3 years ago

Answer:

Option A) (-x^2 - 2x + 4)-(x^2 + 2x +1)= -2x^2-4x +3 is modeled by the algebra tiles

Step-by-step explanation:

Given (-x^2 - 2x + 4)-(x^2 + 2x +1)= -2x^2-4x + 3

To verify that the given sum or difference is modeled by the algebra tiles

Now applying the algebraic sum operations we get

(-x^2 - 2x + 4)-(x^2 + 2x +1)=-x^2 - 2x + 4 - x^2 - 2x -1

= -2x^2-4x + 3   ( using algebraic sum operations )

Therefore (-x^2 - 2x + 4)-(x^2 + 2x +1)=-2x^2-4x + 3

Option A)  (-x^2 - 2x + 4)-(x^2 + 2x +1)=-2x^2-4x + 3 is modeled by the algebra tiles

Which linear inequality is represented by the graph?
aalyn [17]

Answer:

y ≤ 1/3 x - 1.3.

Step-by-step explanation:

First find the equation of the line:

The slope = (-0.3 - (-1.3) / (3 - 0).

= 1/3 so the equation is y = 1/3x + b where b is a constant.

b is the y-intercept which is the value of y when x  = 0 . We see that it is -1.3 ( from the point 0, -1.3).

Since the line is continuous and the shading is below this line the inequality sign is 'less than or equal to',  ≤.

For which equations does the fraction 2/3 make the equation true? Choose all that apply A. 35x__=20 B. 26x__=18 1/3 C. 48x__32 D
Rama09 [41]

Answer:

C. 48x = 32

Step-by-step explanation:

For which equations does the fraction 2/3 make the equation true? Choose all that apply

Solving

A. 35x =20

x = 20/35

x = 4/7

B. 26x=18

x = 18/26

x = 9/13

C. 48x = 32

x = 32/48

x = 2/3

D. 22x =14

x = 14/22

x = 7/11

The correct Option is Option C
