Step-by-step explanation:

Step-by-step explanation:

[tex]v = {x}^{3} \\ {v}^{2} + 3v - 5 = 0 \\ [/tex]

Solving this equation using the quadratic formula, we get two real solutions :

1.1926 or -4.1926

Now we know the values of v , we can calculate x since x is ∛ v

[tex] {x}^{6} + 3 {x}^{3} - 5 = 0[/tex]

[tex]x = \sqrt[3]{1.1926} = 1.0605 \\ x = \sqrt[3]{ - 4.1926} = - 1.6125[/tex]

Answer:

Step-by-step explanation:

1). Let the equation of the line is,

  y = mx + b

  Here, m = slope of the line

  b = y-intercept

  Slope of a line passing through two points,

  m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

  We take two points from the table given (-3, -19) and (0, -1)

  m = [tex]\frac{-19+1}{-3-0}[/tex]

  m = 6

  y - intercept 'b' = -1 [For x = 0]

  Therefore, equation of the line will be,

  y = 6x - 1

2). Equation of a line passing through a point (x', y') is,

   y - y' = m(x - x')

   Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

   m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

   We take two points from the given table as (2, 12) and (3, 18).

   Slope of the line passing through these points will be

   m = [tex]\frac{18-12}{3-2}[/tex] = 6

   Equation of the line passing through (2, 12) will be,

   y - 12 = 6(x - 2)

   y = 6x - 12 + 12

   y = 6x

By using a graphing tool we can graph these lines representing the tables.    

Answer:

68.000 acres x 0.6% = 408 acres

Step-by-step explanation:

Answer:

50º & 40º

Step-by-step explanation:

complementary anlges add up to 90º. so, we can make an equation:

x+x-10=90

2x=100

x=50

so the angles are 50º and 40º.

Answer:

Step-by-step explanation:

.. 3 + 2[4(2) – (4 + 3(2))]. 3 + 2[8 – (4 + 6)]. 3 + 2[8 – (10)]. 3 + 2[–2]. 3 – 4. –1 ... 2x + 6 = 4 – 2 + 1x. 2x + 6 = 2 + x. 2x – x + 6 = 2 + x – x. x + 6 = 2. x + 6 – 6 = 2 – 6. x = –4.

Step-by-step explanation:

Let the volume of 25% ethanol be x, then volume of 85% ethanol will be (20 - x)

The ethanol content is:

11.67 gallons of 25% ethanol and

20 - 11.67 = 8.33 gallons of 85% ethanol

Answer:

$275

Step-by-step explanation:

30% + 15%=45%

45% of 500 is 225, because 500 x 0.45=225. Then subtract the discount from the total, 500 - 225, and you get 275

Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112

Answer: 19 people

Step-by-step explanation:

If every 4th customer received a free gingerbread man cookie and 29 cookies were given away then the number of customers that came were:

= 4 * 29

= 116 customers

Because 116 customers came, they were able to give 29 cookies by giving one to every 4th customer.

If there were 116 customers, the number of customers who got the free candy canes would be:

= 116/6

= 19.3

= 19 people

Answer:

2x(5x + 14) + 15

Step-by-step explanation:

Given: (2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 2[tex]x^{2}[/tex](4x + 5) + 3(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

                              = (8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15) - 8[tex]x^{3}[/tex] + 16x

                              = 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15 - 8[tex]x^{3}[/tex] + 16x

collecting like terms to have,

8[tex]x^{3}[/tex]- 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 16x + 15

10[tex]x^{2}[/tex] + 28x + 15

Thus,

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 10[tex]x^{2}[/tex] + 28x + 15

                                           = 2x(5x + 14) + 15

Answer:

4 miles per hour

Step-by-step explanation:

Total miles = 1/2

Time taken = 1/8

Miles per hour = 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4 miles per hour

Bryan’s mile per hour = 4

4 miles per hour

Answer:

y=-2x+17

Step-by-step explanation:

So the problem is 2x+y=17, we know that slope intercept form is y=mx+b where m is the slope and b is the y-int.

All you have to do is isolate the y.

2x+y=17

-2x on both sides so you can leave the y alone.

y=-2x+17 should be the answer. Hope this helps!
