Answer:

5x⁴ + 7x or x(5x³ + 7 )

Step-by-step explanation:

Given expression:

        5x⁴ - 7(-x )

To simplify this expression, we have to follow the order of operation PEMDAS;

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction

  5x⁴ - 7(-x ) = 5x⁴ + 7x

               Since x is common to both terms;

                = x(5x³ + 7 )

So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )

Answer:

The first one: if 2/3 is 12 then 1/3 is 6. 3/3 is 18. SO Jane had 18 stuffed animals  before the donation.

The second one: 25 students then 13 are men so 25-13 is 12. 12/25 as a percentage is 48%

Hope this helps!

Answer:

[tex]Section \: A. \\before \: the \: donation \ : jane \: had \: \boxed{18 \: (stuffed \: animals)} \\

Section B.\\

\boxed{the\: percentage\: of\: female\: student\: is\: \boxed{48 \%}}

[/tex]

Step-by-step explanation:

[tex]Section A.\\let \: the \: total \: animals \: be \to \: t_{a} \\ let \: the \: donated\: animals \: be \to \: d_{a} \\ then \to \\ if \: d_{a} = \frac{2}{3} (t_{a} ) : we \: can \: find \: t_{a} \: by \to \\ 12 = \frac{2}{3} (t_{a} ) \\ 2(t_{a} )= 12 \times 3 \\ t_{a} = \frac{36}{2} \\ \boxed{ t_{a} = 18.}

\\ \\

Section B.\\

let \: the \: total \: number\: of \: students\: be \: be \to \: t_{s} \\ let \: the \: number\: of \: male\: student\: be \: be \to \: m_{s} \\ then \to \\ if \: t_{s} = m_{s} +1 3 \: then \\

m_{s} = t_{s} -13\\

m_{s} = 25-13 \\

m_{s} =12 \\

hence \: percentage \: of \: girls \: is = \frac{12}{25} \times 100 \\

the \: percentage\: is \to \boxed{m_{s} = 48\%}

Answer: he is 11 years old

Step-by-step explanation: 44 divided by 4 = 11

Answer 44 divided by 4 (11)

Answer:

9) -25/21

11) 14

Step-by-step explanation:

In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.

9)

y-coordinates: -10 - 15 = -25

x-coordinates = 6 - (-15) = 21

slope = (difference in y)/(difference in x) = -25/21

11)

y-coordinates: -20 - 8 = -28

x-coordinates = 3 - 5 = -2

slope = (difference in y)/(difference in x) = -28/(-2) = 14

Answer: 3,250

Step-by-step explanation:

Given:

Amount saved in sale = $25

Sale price was 35% off the regular price.

To find:

The regular price of the tennis shoes.

Solution:

Let the regular price of the tennis shoes be x.

Sale price was 35% off the regular price.

[tex]Discount=\dfrac{35}{100}x[/tex]

Amount saved in sale = $25

[tex]0.35x=25[/tex]

Divide both sides by 0.35.

[tex]x=\dfrac{25}{0.35}[/tex]

[tex]x=71.42857[/tex]

[tex]x\approx 71.43[/tex]

Therefore, the regular price of the tennis shoes is $71.43.

Step-by-step explanation:

one minute is 60 seconds

17500 divided by 60

y-intercept = (0, 4)

x-intercept = (3/4, 0)

1 - Find the slope

[tex]slope = m = \frac{rise}{run} = \frac{y_2~-~y_1}{x_2~-~x_1} = \frac {-11-10}{5-(-2)} = \frac {-21}{7} = -3[/tex]

2 - Plug the slope into y = mx + b and substitute a point into x and y to find the y-intercept, b, by isolating it.

y = mx + b

y = -3x + b

10 = (-3)(-2) + b

10 = 6 + b

-6   -6

4 = b

y-intercept = (0, 4)

3 - Rewrite the completed formula

y = -3x + 4

4 - Substitute 0 in for y to find the x-intercept

0 = -3x + 4

-4          - 4

-4 = -3x

-4/-3 = -3x/-3

 4/3 = x

x-intercept = (4/3, 0)
