Answer: The first 3 options

Step-by-step explanation:

You have to make sure that the given variable would be able to equal -5. The  \(\geq\) sign in the second and third answer show that the variable could be equivalent to -5.

Answer:

g > -7, f ≤ -5 and g ≥ -5

Step-by-step explanation:

the < and > symbols mean less than and greater than respectively, but not including. Therefore -5 cannot be a valid solution if the range is (for example) g > -5. However, ≤ and ≥ mean less/greater than or equal to, so -5 would be a valid solution for g ≥ -5 (for example).

Answer:

distance: 2

midpoint: -4,-3

We are given the line's slope and the line's y-intercept (the point where the line touches the y-axis)

It's easier to write the equation in Slope-Intercept Form, which looks like so:-

\(\boxed{y=mx+b}\)

where m -> slope of the line & b -> y-intercept

Instead of m, you should plug in 6:-

y=6x+b

Instead of b, you should plug in 2:-

y=6x+2 ✓

Answer:

The solution is x = -2 and y = 2.

Step-by-step explanation:

Given that:

14y - 8x = 44      Eqn 1

-7y = -x - 16       Eqn 2

In elimination method, you try to eliminate one variable in the equation by adding or subtracting.

Multiplying Eqn 2 by 2

2(-7y = -x - 16)

-14y=-2x-32

-14y+2x= -32    Eqn 3

Adding Eqn 1 and 3

(14y-8x)+(-14y+2x)=44+(-32)

14y-8x-14y+2x=44-32

-6x=12

Dividing both sides by -6

\(\frac{-6x}{-6}=\frac{12}{-6}\\x=-2\)

Putting x=-2 in Eqn 2

-7y=-(-2)-16

-7y=2-16

-7y=-14

Dividing both sides by -7

\(\frac{-7y}{-7}=\frac{-14}{-7}\\y=2\)

Hence,

The solution is x = -2 and y = 2.

The x and y-intercepts of the line equation 6x - 2y = -18 are ( -3,0 ) and ( 0,9 ) respectively.

Given the equation of line;

To find the x-intercept, substitute in 0 for y in the equation and solve for x.

6x - 2y = -18

6x - 2(0) = -18

6x - 0 = -18

6x = -18

Divide both sides by 6

6x/6 = -18/6

x = -18/6

x = -3

Hence, x-intercept is ( -3,0 ).

To find the y-intercept, substitute in 0 for x in the equation and solve for y.

6x - 2y = -18

6(0) - 2y = -18

0 - 2y = -18

-2y = -18

Divide both sided by -2

y = -18 / -2

y = 9

The y-intercept is ( 0,9 ).

Therefore, option D is the correct answer.

The equation of the straight line through the origin and at right angles to the line x² - 5xy + 4y² = 0 is y = (-5/4)x.

Given, the equation of the straight line is x² - 5xy + 4y² = 0. We need to find the equation of the straight line through the origin and at right angles to the line x² - 5xy + 4y² = 0.

Let's find the slope of the given line: x² - 5xy + 4y² = 0⇒ 4y² - 5xy + x² = 0. Comparing it with the standard form, we get, A = 4, B = -5, and C = 1.M = -A/B. Slope of the line is M = -4/-5 = 4/5.

We know that the product of the slopes of the two perpendicular lines is -1. Let's find the slope of the required line,m1 × m2 = -1(4/5) × m2 = -1m2 = -5/4. The slope of the required line is m = -5/4.

As the line passes through the origin, the equation of the line is of the form y = mx. On substituting the value of m, we get the required equation: y = (-5/4)x.

The total cost of the guitar including sales tax is $85.31

A sales tax is a tax levied on the sale of certain goods and services and paid to the government. In general, rules compel the seller to collect tax money from the buyer at the time of purchase.

The tax is added on the sale price and it is not apart of the profit.

Cost of the guitar = $131.25

Sales tax = 6.5%

Total cost of guitar = 6.5% of 131.25 = 0.65 × 131.25 = $85.31

A use tax is a levy on services or goods that a client pays directly to a governing body. Food, education, and medications are usually exempt from sales and use tax under state law.

Answer:

n = p+3q

Step-by-step explanation:

2^p x 8^q = 2^n

Exponent rules

Rewriting 8 as 2^3

2^p x 2^3^q = 2^n

Using the rule a^b^c = a^(b*c)

2^p x 2^3q = 2^n

Using the rule a^b * a^c = a^(b+c)

2 ^(p+3q) = 2^n

Since the bases are the same, the exponents are the same

p+3q = n

Answer:

\( \sf \: p + 3q = n\)

Step-by-step explanation:

\(2^p*8^q=2^n\)

First, write 8^q as a power of 2.

\(2^p*8^q=2^n\\2^p*2^3^q=2^n\)

As all the bases are same, exponents are also equal.

Now add the powers.

∴ p + 3q = n

Answer:

Pizza 1: lenght(l)=16 and width(w)=4

Perimeter=40in.

Pizza 2: l=32 and w=2

Perimeter=68in.

Step-by-step explanation:

1. List down factors of 64.

64=1,2,4,8,16,32,64

2. Select the factors you'll be using to draw your rectangles. In this case I selected the factors 2,4,16 and 32 because area of rectangle=l×w. Therefore 2×32=64 and 4×16=64.

3. Draw your rectangles according to the measurements you chose. If the drawing is too big to fit the box you can simply use a scale. Such as 1 inch=4 inches on your drawing. For example, when drawing the length of the second Pizza which is 32in. you can simply draw a line of 8 inches.

4. After drawing your pizzas you niw have to find the Perimeter of both. Simply use the formula Perimeter of a rectangle=2(l+w)

Pizza 1: Perimeter=2(16+4)

=2×20

=40in.

Now do the same for Pizza 2 using its own lengjt and width. Hope this helped.

D) This is a voluntary response sample. It will almost certainly overestimate the level of displeasure among the city's residents.

The sample is voluntary response because the residents themselves chose whether or not to respond to the announcement in the newspaper. This type of sampling is often biased because those who choose to respond may not be representative of the entire population. In this case, those who are particularly unhappy with the condition of the city's roads may be more likely to respond, while those who are satisfied with the roads may not feel the need to respond. Therefore, the sample is likely to overestimate the level of displeasure among the city's residents.

Given:

Speed to train = 200km/h

The train sets off from Station A at 12:24.

Reaches station B at 14:12.

To find:

The distance between both stations.

Solution:

We have,

Speed to train = 200km/h

Time taken by the train to cover the distance between station A and station B is the difference between 14:12 and 12:24.

Time = 1 hr 48 min

Time = 1.8 hours            [ 1 hr = 60 minutes]

Let d be the distance between both stations.

We know that,

\(Speed=\dfrac{Distance}{Time}\)

\(200=\dfrac{d}{1.8}\)

\(200\times 1.8=d\)

\(360=d\)

Therefore, the distance between the two stations is 360 km.

There are 95% confident that the true population mean textbook weight lies between 41.231 and 48.769 ounces, based on the sample of 20 randomly selected textbooks with a mean weight of 45 ounces.

We can use the formula to calculate the confidence interval:

Confidence interval = Sample mean ± (Z-score x Standard error)

First, we need to find the Z-score for the 95% confidence interval, which is 1.96.

The standard error is calculated as the population standard deviation divided by the square root of the sample size:

Standard error = Population standard deviation / sqrt(sample size)

Standard error = 8.6 / √(20)

Standard error = 1.923

Now we can substitute the values into the formula:

Confidence interval = 45 ± (1.96 x 1.923)

Confidence interval = 45 ± 3.769

Confidence interval = (41.231, 48.769)

Therefore, we can be 95% confident that the true population mean textbook weight lies between 41.231 and 48.769 ounces, based on the sample of 20 randomly selected textbooks with a mean weight of 45 ounces.

To determine which set of data most likely has a mean closest to 29.5, we need to analyze the shape and position of the histograms in relation to the value 29.5.

Looking at the histograms described:

The first histogram ranges from 9 to 48, and the upward trend starts from 1 and ends at 33, followed by a downward trend. This histogram suggests that there may be values lower than 29.5, which would bring the mean below 29.5.

The second histogram ranges from 15 to 48, with an upward trend from 1 to 30 and then a downward trend. Similar to the first histogram, it suggests the possibility of values lower than 29.5, indicating a mean below 29.5.

The third histogram ranges from 12 to 56, and the upward trend starts from 1 and ends at 32, followed by a downward trend. This histogram covers a wider range but still suggests the possibility of values below 29.5, indicating a mean below 29.5.

The fourth histogram ranges from 15 to 54 and exhibits multiple trends. While it has fluctuations, it covers a wider range and includes both upward and downward trends. This histogram suggests the possibility of values above and below 29.5, potentially resulting in a mean closer to 29.5.

Based on the descriptions, the fourth histogram, with its more varied trends and wider range, is most likely to have a mean closest to 29.5.
