Drag each tile to the correct location on the algebraic problem. Not all tiles will be used,

Tema [17]

Answer/Step-by-step explanation:

4x - 7 = -2x + 12 (Given)

Add 2x to both sides

4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)

6x - 7 = 12 (Simplication)

Add 7 to both sides

6x - 7 + 7 = 12 + 7 (Addition property of equality)

6x = 19 (Simplification)

Divide both sides by 6

$\frac{6x}{6} = \frac{19}{6}$ (Division property of equality)

$x = \frac{19}{6}$

FrozenT [24]

Answer:

1. Quantitative

2. Quantitative

3. Qualitative

4. Qualitative

5. Quantitative

Step-by-step explanation:

A variable is quantitative if it assumes numerical values, for example 1,2,3.

If it assumes "labels", for example good or bad, it is qualitative.

1. Rating of the quality of a movie on a 7-point scale

It assumes numerical values, for example, 1,2,3,...

So it is quantitative

2. Age

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

3. Country you were born in

Descriptive, such as Brazil, USA, Colombia, ...

So it is qualitative.

4. Favorite Color

Descriptive, such as black, brown, red, blue

So it is qualitative

5. Time to respond to a question

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

Solve x²+5x+6=0 by completing the square

Brums [2.3K]

Answer:

x = -2

x= -3

Step-by-step explanation:

x 2+5x+6=0

To solve the equation, factor x^2+5x+6 using formula x^2+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.

a+b=5

ab=6

Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 6.

1,6

2,3

Calculate the sum for each pair.

1+6=7

2+3=5

The solution is the pair that gives sum 5.

a=2

b=3

Rewrite factored expression (x+a)(x+b) using the obtained values.

(x+2)(x+3)

To find equation solutions, solve x+2=0 and x+3=0.

x=−2

x=−3
