Answer:

x^2   + 3x    + 4

Step-by-step explanation:

(3.x2 – 2x + 5) - (2x2 – 5x + 1)    Combine like terms:  x^2, x and constants:

3x^2 - 2x^2  -2x + 5x  + 5 - 1

This condenses to

     x^2   + 3x    + 4

Answer:

x = 6

x = 1

Step-by-step explanation:

(3x² - 2x + 5) - (2x² - 5x + 1)

= 3x² - 2x² - 2x - 5x + 5 + 1

= x² - 7x + 6

= (x - 6)(x - 1)

x - 6 = 0

x = 6

x - 1 = 0

x = 1

Answer:

• 25%

• Drama movie

Step-by-step explanation:

• Total number of children

= 16 +12 +18 +20 +14

= 80

Percentage of children that voted for action movie

=  \frac{no. \: of \: children \: that \: voted \: for \: action \: movie}{total \: number \: of \: children} \times 100\%

=  \frac{20}{80}  \times 100\%

=\textbf{25\%}

------------------------------------------------------------

• Total number of votes

= 30 +32 +36 +36 +26

= 160

20% of total votes

= 20% ×160

= 32 votes

Since Drama movie received 32 votes, it received 20% of the total votes.

Enter the correct answer in the box. Write your answer in the form y = mx + b, using the appropriate inequality symbol in place
Afina-wow [57]

Step-by-step explanation:

the delimiter line is going through the points (-4, 0) and (0, -4).

the line function

y = mx + b

m is the slope of the line, b is the y-intercept (the y value when x = 0).

the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to another.

so, for the 2 found points :

x changes by +4 (from -4 to 0)

y changes by -4 (from 0 to -4).

the slope m is then

-4/+4 = -1

and the y-intercept is -4 (as explained).

so, the line is

y = -x - 4

and the graphic says that all values greater than our equal to the line values are valid, so

y >= -x - 4
