Answer:

No, for various value of x the number of tickets sold by me and my friend for the fundraiser can vary but will always remain in the ratio of 11:5.

Step-by-step explanation:

It is given that for a fundraiser, the ratio of tickets you sold to tickets your friend sold was 11:5.

Let us look at the ratio of tickets sold by both the persons.

Now, according to the condition given and the ratio mentioned in the question;

The number of tickets sold by me for the fundraiser be = 11x

and

The number of tickets sold by my friend for the fundraiser be = 5x

It is observed that total number of tickets sold by me and my friend are;

=> 11x + 5x

So, it is inferred that the number of tickets sold by me and my friend are not 11 and 5 respectively and can vary upon the value of x.

For instance, if the value of x = 2 than;

=> 11x + 5x

=> 11 × 2 + 5 × 2

=> 22 + 10

=> 32 tickets

Therefore,

No, for various value of x the number of tickets sold by me and my friend for the fundraiser can vary but will always remain in the ratio of 11:5.

Solving the inequality for the absolute value of x gives x < 1

Inequalities are simply defined as mathematical expressions showing comparison between two equations that are unequal.

They are known for explaining the relationship between values that are not equal to each other.

It is also important to note that absolute values of numbers holds that no number carries the negative sign

It is denoted with the symbol ' | | '

Given the expression;

| | 3x - 1 | + 5 | < 1

expand the bracket

3x - 1 + 5 < 1

Take absolute value

3x - 1 + 5 < 1

collect like terms

3x - 1 < 1 - 5

3x < -4

3x < - 4 + 1

3x < - 3

Make 'x' the subject

x < -3/ 3

x < - 1

x < 1

Thus, solving the inequality for the absolute value of x gives x < 1

I just answered something very similar to this haha, but the sum of all exterior angles, regardless of the polygon's sides is always equal to 360 degrees, so our sum is 360°

Applying the midpoint formula, the endpoints for the midsegment are (-0.5, 0.5) and (-5/2, -7/2).

The midsegment of a trapezoid is the line segment that intersects the two legs of the trapezoid at their midpoints.

Hence, to find the endpoint for the midsegment of the other leg of the trapezoid, apply the midpoint formula, M[(x2 + x1)/2, (y2 + y1)/2].

Find the midpoint between A(-2, -5) and B(-3, -2):

A(-2, -5) = (x1, y1)

B(-3, -2) = (x2, y2)

Plug in the values

M[(-3 + (-2))/2, (-2 + (-5))/2]

M(-5/2, -7/2)

Therefore, using the midpoint formula, the endpoints for the midsegment are (-0.5, 0.5) and (-5/2, -7/2).

Answer:

log₇(xy/z)

Step-by-step explanation:

We know that

[tex]\log_ax = b \implies a^b = x[/tex]

we also know that:

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

so it follows that

[tex]\log_ax + log_ay = log_a(xy)[/tex]

from:

[tex]\frac{a^b}{a^c} = a^{b - c}[/tex]

follows that

[tex]\log_ax - log_ay = log_a(\frac{x}{y})[/tex]

so

[tex]\log_7x + \log_7y - \log_7z = \log_7(xy) - \log_7z = \log_7(\frac{xy}{z})[/tex]

I did number 11 and 13 for you and gave an explanation, I hope this helped, if you need more help just comment and let me know, have a great day! <3

Step-by-step explanation:

If the equation is addition like number 11, all you have to do is subtract 1.7 from the solution; which is 4.98. It will look like this:

4.98 - 1.7 = 3.28

if the equation is subtraction like number 13, then you have to add 6.55 with the solution, which is 2.45, it will look like this:

6.55 + 2.45 = 9

Answer: Total temperature = -6.66ºF

Step-by-step explanation:

Given data,

First temperature = 1.3ºF

Second temperature = -2.8ºF

Fest = 10.000

So,

We can write,

                      1.3º x + (-2.8º) x = 10.000

                          x (1.3º - 2.8º) = 10.000

                            x (-1.5º) = 10.000

                               x = 10.000/-1.5º

                               x = -6.66ºF

Therefore,

          Total temperature = -6.66ºF

The relationship is proportional because, the points lie on a straight line that goes through the origin.

A relationship that is proportional has a straight line graph that must pass through the origin, whereby the constant of proportionality, k = y/x, where x and y are the variables of the proportional relationship.

An example of a graph that represents a proportional graph is shown in the attachment below. The graph is a straight line graph that passes through (0, 0), which is the origin. The constant of proportionality, k = 21/7 = 3.

1. The slope-intercept equation of the line is: y = x - 3.

2. The equation of the line in standard form is: -1/5x + y = 5

3. The equation in point-slope form is: y + 7 = 14(x + 2)

4. The value of x ≈ 5.94

Slope (m) = y2 - y1/x2 - x1.

There are three ways too write the equation of a line, they include:

1. find the slope (m) of the line that passes through (8, 5) and (7, 4):

Slope (m) = (5 - 4)/(8 - 7)

Slope (m) = 1/1

Slope (m) = 1

Substitute m = 1 and (a, b) = (8, 5) into y - b = m(x - a):

y - 5 = 1(x - 8)

y - 5 = x - 8

y = x - 8 + 5

y = x - 3

The slope-intercept equation is: y = x - 3.

2. The slope of perpendicular lines are negative reciprocals, therefore, the slope of the line perpendicular to the line that has a slope of -5 would be, m = 1/5.

Substitute m = 1/5 and (a, b) = (-15, 2) into y - b = m(x - a):

y - 2 = 1/5(x - (-15))

y - 2 = 1/5(x + 15)

y - 2 = 1/5x + 3

y = 1/5x + 3 + 2

y = 1/5x + 5

-1/5x + y = 5 [standard form]

3. Parallel lines have the same slope. The slope of y = 14x - 3 is 14. The line that is parallel to y = 14x -3 would also be, m = 14.

Substitute m = 14 and (a, b) = (-2, -7) into y - b = m(x - a):

y - (-7) = 14(x - (-2))

y + 7 = 14(x + 2) [point-slope equation]

4. y = kx

1.4 = k3.2

1.4/3.2 = k

The equation would be: y = 1.4/3.2x

Substitute y = 2.6 to find x:

2.6 = 1.4/3.2x

(2.6)(3.2) = 1.4x

8.32 = 1.4x

8.32/1.4 = x

Using scientific notation, the total kilowatt-hours of electricity used during these two years is:

(6.03 x 10^9) + (4.3 x 10^11) = (0.0603 x 10^11) + (4.3 x 10^11) = 4.3603 x 10^11

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

With the base being [tex]a \in [1, 10)[/tex].

For two numbers in scientific notation to be added or subtracted, they need to have the same exponent.

Thus, the first amount has to have an exponent of 10^11, meaning that the exponent has to be added by 2 = equivalent to addition by 100, and to compensate the base has to be divided by 100, hence:

(6.03 x 10^9) + (4.3 x 10^11) = (0.0603 x 10^11) + (4.3 x 10^11) = 4.3603 x 10^11

Step-by-step explanation:

Based on the alternate exterior angles theorem, the equation is: 15x - 3 = 14x + 2

The value of x = 5.

The angles, (15x - 3) and (14x + 2) are alternate exterior angles. Based on the alternate exterior angles theorem/postulate, they are congruent to each other.

Thus, the equation to create in solving for the value of x would be:

15x - 3 = 14x + 2

Subtract 14x from both sides of the equation

15x - 3 - 14x = 14x + 2 - 14x [subtraction property of equality]

x - 3 = 2

Add 3 to both sides

x - 3 + 3 = 2 + 3 [addition property of equality]

x = 5

In summary, based on the alternate exterior angles theorem, the equation is: 15x - 3 = 14x + 2

The value of x = 5.
