Answer:

true I think. I rember some, sorry if its wrong

Answer:

1/5

Step-by-step explanation:

If you focus on one of the coordinates, for example (10,10) you will notice that 10 divided by 5 equals 2.  If you do that on both X and Y it will give you 2.  The black shape's top right cordinate is (2,2) which explains why its 1/5...

Answer:

9.5 < x < 15

Step-by-step explanation:

The possible values of x for the given problem lies in  (-infinity, -1.33) ∪ (9.5, 15).

Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.

Unlike a linear equation it can have a range of values inside an interval.

Given that,

The sides of the triangle are as follows,

CD = x - 4,  DE = 3x + 21 and  CE = 6x - 13.

There can be three cases for the given problem.

Case 1,

The longest side of the triangle is CE = 6x - 13.

Since the sum of the two sides of a triangle is always greater than the longest one, the following inequality can be written for the given triangle,

6x - 13 < x - 4 + 3x + 21

=> 6x - 13 < 4x + 17

=> 6x - 4x < 17 + 13

=> 2x < 30

=> x < 15

Case 2,

The longest side of the triangle is DE = 3x + 21.

Since the sum of the two sides of a triangle is always greater than the longest one, the following inequality can be written for the given triangle,

3x + 21 < 6x - 13 + x - 4

=> 3x + 21 < 7x - 17

=> 7x - 3x > 21 + 17

=> x > 38/4

=> x > 9.5

Case 3,

The longest side of the triangle is CD = x - 4.

Since the sum of the two sides of a triangle is always greater than the longest one, the following inequality can be written for the given triangle,

x - 4 < 3x + 21 + 6x - 13

=>  x - 4 < 9x + 8

=> x - 9x > 8 + 4

=> x < -1.33

Thus, the range of the values of x is intersection of x < 15, x > 9.5 and  x < -1.33, which is equivalent to (-infinity, -1.33) ∪ (9.5, 15).

Hence, the range of possible values of x lies in the interval (-infinity, -1.33) ∪ (9.5, 15).

Answer:

Large avocados should cost $ 1.83 or less to be a good deal.

Step-by-step explanation:

Since there are two types of avocado in the store, some small at $ 0.92 and others larger, to determine at what price large avocados would be a good deal, an equivalence must be established in this regard:

Thus, if two small avocados are equal to one large, buying two small avocados at $ 0.92 the total price would be $ 1.84. Therefore, any large avocado that sells for less than $ 1.84 would be a good deal. Thus, large avocados should cost $ 1.83 or less to be a good deal.

Answer:

5 and 5b: y=-2x+10

5a: y-2=-2(x-6)

Step-by-step explanation:

We can use the mentioned data points to identify the slope. Time will always the x coordinate/axis, so gallons will be the y coordinate/axis. As you probably already know, slope is rise over run, so we can measure the change in y over the change in x, or we can do [tex]\frac{y-y_{1}}{x-x{1}}[/tex]. When we plug in our points, (2,6) and (5,0), we get  [tex]\frac{6-0}{2-5}[/tex], or [tex]\frac{6}{-3}[/tex], or [tex]\frac{2}{-1}[/tex], or simply -2. So our slope is -2.

We can use our y-intercept (which is (0,10), as mentioned in the attached graph and table) to make the equation, in slope-intercept form, [tex]y=-2x+10[/tex] This can answer both question 5 and 5b. Remember that slope-intercept form is written using the format y=mx+b, where x any given x-coordinate, y is the corresponding y-coordinate, m is the slope and b is the y-intercept.

To put this equation in point-slope form, one must first remember that point-slope form is written in the format [tex]y-y_{1} = m(x-x_{1})[/tex], using the coordinates of any given coordinates on the same line, except for the y intercept. m also represents slope in this equation. So for this one, we can easily use (2,6). we can plug in these coordinates to get the equation y-2=-2(x-6).

Hope this helps.

c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.

Step-by-step explanation:

We are given the graph of a function of the distance in function of the time.

We want to study the graph during the part of the graph labeled K, which is non-linear, meaning that the accelaration is not constant. This means that the car travels different distances per unit of time, and the correct answer is:

c. The car travels different distances per unit of time because the portion shows a nonlinear, increasing function.

Answer:

The value of x will be:

[tex]x=22\sqrt{2}[/tex]

or

[tex]x = 31.1[/tex]

Step-by-step explanation:

Given

To determine

hypotenuse x = ?

For a right-angled triangle with sides, a and b the hypotenuse c is defined as

[tex]c=\sqrt{a^2+b^2}[/tex]

substituting a = 22, b = 22 and c = x

[tex]x=\sqrt{22^2+22^2}[/tex]

[tex]x=\sqrt{22^2\cdot \:2}[/tex]

Apply radical rule:  [tex]\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0[/tex]

[tex]x=\sqrt{2}\sqrt{22^2}[/tex]

[tex]x=22\sqrt{2}[/tex]

or

[tex]x = 31.1[/tex]

Therefore, the value of x will be:

[tex]x=22\sqrt{2}[/tex]

or

[tex]x = 31.1[/tex]

Answer:

x = {0, π/3, π, 4π/3}

Step-by-step explanation:

4cos⁴(x) - 5cos²(x) + 1 = 0

(u² - 1)(4u² - 1) = 0

u² - 1 = 0

u² = 1

u = ± 1

cos x = ± 1

=> x = 0 or π

4u² - 1 = 0

4u² = 1

u² = 1/4

u = ± 1/2

cos x = ± 1/2

=> x = π/3 or 4π/3

Therefore, x = {0, π/3, π, 4π/3}.

Answer:

The value of f(x) - g(x) is:

f(x) - g(x) =  2x² + 6x - 4

Step-by-step explanation:

Given

f(x) = 3x² + x - 3

g(x) = x² - 5x + 1

To determine

f(x) - g(x)

Using the formula

f(x) - g(x) =  3x² + x - 3 - ( x² - 5x + 1)

              = 3x² + x - 3 - x² + 5x - 1

              = 2x² + 6x - 4

Therefore, the value of f(x) - g(x) is:

f(x) - g(x) =  2x² + 6x - 4

Given:

To find:

The rate of change the given linear function.

Solution:

From the given graph it is clear that the line passes through the points (0,1) and (1,-1). So, rate of change is

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

[tex]m=\dfrac{-1-1}{1-0}[/tex]

[tex]m=\dfrac{-2}{1}[/tex]

[tex]m=-2[/tex]

Therefore, the rate of change of the given linear function is -2. Hence, the correct option is A.

Answer:

Step-by-step explanation:

Total earnings = $1038

Base salary = $675

What part of the total earnings was from the commission?

$1038 - $675 = $363

She made $363 in commissions.

The commissions are 8.75% of the sales.

Let sales = x.

8.25% of x = $363

0.0825x = 363

Divide both sides by 0.0825
