Answer:

x < [tex]\frac{33}{4}[/tex]

Step-by-step explanation:

Given

- 4x + 35 > 2 ( subtract 35 from both sides )

- 4x > - 33

Divide both sides by - 4, reversing the symbol as a result of dividing by a negative quantity.

x < [tex]\frac{33}{4}[/tex]

Answer:

9 days

Step-by-step explanation:

First, write the equation for Daniel's situation:

D = 17t + 49

Then, write the equation for Audrey's situation:

A = 20t + 22

Then, set these equations equal to each other and solve for t to find when they will be on the same page:

17t + 49 = 20t + 22

Solve for t:

17t + 49 = 20t + 22

49 = 3t + 22

27 = 3t

9 = t

So, they will be on the same page 9 days into the month.

Answer:

Question 4

Simplifying the expression [tex]\frac{x^2-10x-24}{x^2-3x-108}[/tex] we get [tex]\frac{x-2}{x-9}[/tex] and x≠9 or x≠2

Option D is correct option.

Question 5

Simplifying the expression: [tex]\frac{8x-16}{x^2-13x+22}[/tex] we get [tex]\frac{8}{x-11}, x\neq 11[/tex]

Option C is correct.

Step-by-step explanation:

Question 4

Simplify completely [tex]\frac{x^2-10x-24}{x^2-3x-108}[/tex]

For simplifying the above expression we have to find find factors of numerators and denominators

First finding factors of numerator [tex]x^2-10x-24[/tex]

[tex]x^2-10x-24\\ = x^2-12x+2x-24 \\= x(x-12)+2(x-12) \\=(x-12)(x-2)[/tex]

So, the factors of [tex]x^2-10x-24[/tex] are [tex](x-12)(x-2)[/tex]

Now finding factors of denominator [tex]x^2-3x-108[/tex]

[tex]x^2-3x-108\\=x^2-12x+9x-108\\=x(x-12)+9(x-12)\\=(x+9)(x-12)[/tex]

So, factors of [tex]x^2-3x-108 are (x-12)(x+9)[/tex]

Now, replacing numerators and denominators with their factors

[tex]\frac{x^2-10x-24}{x^2-3x-108}\\=\frac{(x-12)(x-2)}{(x+9)(x-12)}\\Cancelling\:(x-12) \: from\:numerator\:and\:denominator\\=\frac{x-2}{x-9}[/tex]

so, simplifying the expression [tex]\frac{x^2-10x-24}{x^2-3x-108}[/tex] we get [tex]\frac{x-2}{x-9}[/tex] and x≠9 or x≠2

Option D is correct option.

Question No 5

Simplify the expression: [tex]\frac{8x-16}{x^2-13x+22}[/tex]

For simplifying the above expression we have to find find factors of numerators and denominators

First finding factors of numerator [tex]8x-16[/tex]

Taking 8 common:

[tex]8x-16\\=8(x-2)[/tex]

So, factors of [tex]8x-16[/tex] are [tex]8(x-2)[/tex]

Now finding factors of denominator : [tex]x^2-13x+22[/tex]

[tex]x^2-13x+22\\=x^2-11x-2x+22\\=x(x-11)-2(x-11)\\=(x-2)(x-11)[/tex]

Now, replacing numerators and denominators with their factors

[tex]\frac{8x-16}{x^2-13x+22}\\=\frac{8(x-2)}{(x-11)(x-2)}\\Cancelling\:(x-2)\\=\frac{8}{x-11}, x\neq 11[/tex]

So, simplifying the expression: [tex]\frac{8x-16}{x^2-13x+22}[/tex] we get [tex]\frac{8}{x-11}, x\neq 11[/tex]

Option C is correct.

Answer:

Slope of the tangent line at x=-1

[tex](\frac{dy}{dx})_{x=-1} = e^{-5}[/tex]

Step-by-step explanation:

Explanation:-

Given function

                            y = f(x) = e ˣ⁻⁴  ...(i)

       Differentiating equation (i) with respective to 'x' , we get

                         [tex]\frac{dy}{dx} = e^{x-4} \frac{d}{dx} (x-4)[/tex]

                       [tex]\frac{dy}{dx} = e^{x-4} (1)[/tex]

Slope of the tangent line

                       [tex](\frac{dy}{dx})_{x=-1} = e^{-1-4} = e^{-5}[/tex]

A. 1 pair of corresponding points are N and L or you could use S and H.

Answer:

Before coming back up to the surface the maximum depth, Cassidy went was 6.25 ft. below the water surface

Step-by-step explanation:

The height of Cassidy's diving platform above the water = 6 ft.

The equation that models her dive is d = x² - 7·x + 6

Where;

d = Her vertical position or distance from the water surface

x = Here horizontal distance from the platform

At Cassidy's maximum depth, we have;

dd/dx = d(x² - 7·x + 6)/dx = 2·x - 7 = 0

x = 7/2 = 3.5

∴ At Cassidy's maximum depth, x = 3.5 ft.

The maximum depth, [tex]d_{max}[/tex] = d(3.5) = 3.5² - 7 × 3.5 + 6 = -6.25

The maximum depth, Cassidy went before coming back up to the surface = [tex]d_{max}[/tex] = -6.25 ft = 6.25 ft. below the surface of the water.

Answer:

Step-by-step explanation:

A bar chart is a graphical representation of data, showing the relationship between two variables in the form of bars. the height of each bar expresses the connection between the variables.

In the given question, plot the number of weeks given against the cost of living index so as to have a clear picture of the relationship between the variables.

The attachment to this answer shows the bar chart for the given data.

Answer:

MO = 22 units

Step-by-step explanation:

To solve this problem, you have to set the equations equal to each other. Since we are given that N is the midpoint, MN and NO are going to be equal to each other.

Set them equal and solve for x:

2x+3 = 3x-1

Subtract 2x from the right to get the variable on one side and add 1 to the right side.

4 = x

Now that we know what x is, you can plug it into the equation and add them together

2(4)+3 = 11

3(4)-1 = 11

11+11 = 22

Hope this helps :)

Given:

Expression is

[tex](3x+4)^2-(x-10)^2[/tex]

To find:

The simplified form of the given expression.

Solution:

We have,

[tex](3x+4)^2-(x-10)^2[/tex]

Using [tex](a+b)^2=a^2+2ab+b^2[/tex] and [tex](a-b)^2=a^2-2ab+b^2[/tex], we get

[tex]=(3x)^2+2(3x)(4)+(4)^2-[(x)^2-2(x)(10)+(10)^2][/tex]

[tex]=9x^2+24x+16-[x^2-20x+100][/tex]

[tex]=9x^2+24x+16-x^2+20x-100[/tex]

On combining like term, we get

[tex]=(9x^2-x^2)+(24x+20x)+(16-100)[/tex]

[tex]=8x^2+44x+(-84)[/tex]

[tex]=8x^2+44x-84[/tex]

Therefore, the correct option is c.

Answer:

373.000

Step-by-step explanation:

From the given information:

Let classify each digit into their place numbers.

The figure given is:

372,998

8 - unit

9 - tens

9 - hundred

2 - thousand

7 - ten thousand

3 - hundred thousand

To round 372,998 to the tenth thousandths position, then we have a decimal in the ten thousand place.

Note: That when determining the tenth thousandth place, we don't have unit position so counting start with 8 as tenth.

i.e.

37.2998 ≅ 373.000

hope that step is enough to give you the two values of y, coz I gat no calc here with me.

hint: use the quadratic equation

Step-by-step explanation:

By Descrates' Rule of Signs,

x² + 99x + 127 changes sign 0 times.

Hence it has 0 positive roots.

Since the discriminant b² - 4ac is also positive, there are 2 real distinct roots.

Hence both the roots are negative. (B)

Answer:

Hi Aarav

Your answer in attached below

LoL

Answer:

y = -3x - 3

Step-by-step explanation:

the y-intercept is -3 as shown in the graph, so, b = -3

if you count, the rise is 3 and the run is -1, so the slope will be -3/1

-3/1 equals to -3

y = -3x - 3

Answer:

y = –3x – 3

Step-by-step explanation:

m = the slope which is 3/1, or 3. Since the line is going from the bottom right corner to the top left, it is a negative slope so –3.

b = the y-intercept which is –3.

So,

y = –3x – 3

Hello!

[tex]\large\boxed{x = 4.21in}[/tex]

Use the Pythagorean Theorem to solve:

a² + b² = c²

We are given the Hypotenuse (c) and one of the legs (b), so we can plug those values in to solve for a:

a² + (6.8)² = 8²

a² + 46.24 = 64

Subtract 46.24 from both sides:

a² = 17.76

Square root both sides:

a = √17.76

a ≈ 4.21 = x
