Answer:

  as written: x = 1/3

  as maybe intended: x =  -5

Step-by-step explanation:

As written

  (1/x) +2 = (2/x) -1

  3 = 1/x . . . . . . . . . add 1-(1/x)

  x = 1/3

__

As maybe intended

  1/(x +2) = 2/(x -1)

  x -1 = 2(x +2) . . . . . . . multiply by (x+2)(x-1)

  x -1 = 2x +4 . . . . . . . . eliminate parentheses

  -5 = x . . . . . . . . . . . . . subtract (x+4)

Answer:

The number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

Step-by-step explanation:

We need to find the number of turns the graph of [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] have?

Turns of graph:

The graphs turns when it changes from increasing to decreasing (rise to fall) or decreasing from increasing (fall to rise)

Turns of graph for a polynomial

A polynomial having degree n will have maximum n-1 turns.

So, for the given polynomial

[tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex]

We need to find degree

The highest exponent of the polynomial is the degree of polynomial

So, Degree n = 5

Number of turns = n - 1 = 5-1 =4

So, the number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

Answer:

Step-by-step explanation:

given: 6 yds / sec

find the time to ride 12 miles,  so how many yards is 12 miles?

12 miles *   1760 yards / 1 mile = 21120 yds

d =r*t    d=distance , r= rate , t = time

we know the distance and the rate .. so we can find the time

d/r = t

21120/6 = t  ( in seconds)

3520 = t sec.

3520 sec *   1 min / 60 seconds   ( to convert to minutes )

3520/60=t ( in minutes)

58 & 2/3  minutes

Answer:

The missing number in the green box is 4

Step-by-step explanation:

The product of the slopes of the perpendicular lines is -1, which means

The slope-intercept form of the linear equation is y = m x + b, where

Let us solve the question

∵ The equation of the first line is y = 4x + 2

→ Compare it with the form of the linear equation above

∴ m = 4

∵ m is the slope

∴ The slope of the line is 4

∵ The slope of the perpendicular line should be the negative reciprocal of it

∵ The negative reciprocal of 4 is [tex]-\frac{1}{4}[/tex]

∴ The slope of the perpendicular line is [tex]-\frac{1}{4}[/tex]

→ Substitute it in the equation

∴ y = [tex]-\frac{1}{4}[/tex] x + 2

∴ The missing number in the green box is 4

Answer:

y = 70°

Step-by-step explanation:

Complementary angles sum to 90°, then

x + y = 90°, that is

20° + y = 90° ( subtract 20° from both sides )

y = 70°

Answer:

[tex]15000 \times {0.92}^{x} = y[/tex]

x is the number of years and y is the value at x years

The exponential decay model to represent the real-life problem should be considered as the [tex]15000 \times 0.92^{x} = y[/tex].

Since the purchase value of the truck is $15,000

The depreciation rate is 8%

So here exponential decay model should be like

[tex]15000 \times 0.92^{x} = y[/tex]

Hence, The exponential decay model to represent the real-life problem should be considered as the [tex]15000 \times 0.92^{x} = y[/tex].

Answer:

What ????????????????

Given:

The expression is

[tex]x^3(2x-6)+x^2(2x-6)[/tex]

To find:

The factors of the given expression.

Solution:

We have,

[tex]x^3(2x-6)+x^2(2x-6)[/tex]

First taking [tex](2x-6)[/tex] common, the given expression can be written as

[tex]=(2x-6)(x^3+x^2)[/tex]

Taking [tex]x^2[/tex] common from [tex](x^3+x^2)[/tex], we get

[tex]=x^2(2x-6)(x+1)[/tex]

Therefore, the factors of the given expression are [tex]x^2(2x-6)(x+1)[/tex].

Answer:

6 F

Step-by-step explanation:

We want to find the temperature difference

Given that the initial temperature read minus 17 F

And the new temperature is increased by 23 F

The new temperature is

=-17+23= 6 F

Therefore the new temperature is 6F

Answer:

19.5 in.

Step-by-step explanation:

Let the width = x.

The length is 3 more than the width, so the length is x + 3.

perimeter = 2 * length + 2 * width

perimeter = 2(x + 3) + 2x

perimeter = 72

2(x + 3) + 2x = 72

2x + 6 + 2x = 72

4x + 6 = 72

4x = 66

x = 16.5

x + 3 = 16.5 + 3 = 19.5

Answer: 19.5 in.

Arithmetic sequence

Step-by-step explanation:

Arithmetic sequences have a common difference d=n2-n1 whilst Geometric sequences have a common ratio r=r2/r1

Clearly, 27-18=9,6-27=9,54-45=9

since there's a common difference,it's an arithmetic sequence

Here, we want to express the given polynomial in the given form while giving the values of a and b

We can rewrite the polynomial as follows;

x^2 + 6x + 9 + 4

We can factorize the first part;

x^2 + 3x + 3x + 9 + 4

x(x + 3)+ 3(x + 3) + 4

= (x + 3)(x + 3) + 4

= (x + 3)^2 + 4

Answer: 18 loaves of bread.

Step-by-step explanation:

Do 12 divided by 2/3 which is the same thing as multiplying 12 by the reciprocal (just flip the fraction) of 2/3 which is 3/2. 12x3/2 is 36/2 which is equal to 18.
