The equation |x| = 77 has two solutions: x = 77 and x = -77. This is because the absolute value of a number reflects its distance from zero, regardless of the direction.

The equation |x| = 77 has two solutions. This is because the absolute value of a number is its distance from zero on a number line, regardless of the direction. Therefore, both 77 and -77 have an absolute value of 77.

To solve for x, you would set up two equations based on the definition of absolute value:

So, the two solutions to the equation |x| = 77 are x = 77 and x = -77.

My calculator says:

16 x 60 = 960

Answer:

-8

Step-by-step explanation:

Given that x and y are two variables.  they are related by the function

y =8-2x

Since x and y are related, given one value we can find the other using this equation.

In our question, given that x =8

Substitute x value in the equation

y = 8-2x

y =8-2(8) = -8

Hence answer is -8:

Verify:  We verify by putting -8 for y and check whether x =8

-8=8-2x

Or 2x = 16

x =8

The density of gold in kilograms per cubic meter is 1.93 x 10³ kg/m³.

The density of gold is 19.3 g/cm³. To find the density in kilograms per cubic meter (kg/m³), we need to convert grams to kilograms and cubic centimeters to cubic meters.

1 g/cm³ = 1000 kg/m³.

Therefore, the density of gold in kg/m³ is 19.3 x 1000 = 1.93 x 10³ kg/m³.

The easiest way to do this is to choose one point from image A. (I am going to choose (-5, -2).  Now, where did that point move to in image A'? (1, 7)

How did the coordinates change?

The x-coordinator changed from -5 to 1 so it moved 6 units to the right.

The y-coordinates changed from -2 to 7 so it moved 9 units up.

When doing this with a graph, you can just count the units.  I only provided the coordinates to help you follow my explanation.

First to find the median we need to put the numbers in order from least to greatest.

62, 64, 65, 66, 67, 69, 83

Now take a number from each side

64, 65, 66, 67, 69

Once again.

65, 66, 67

On last time

66

So the median is 66.

Now to find the mean we must add all the numbers up

64+67+83+65+66+62+69

which equals 476

Now divide 476 by the total number of heights which is 7

476/7=68

So the mean is 68

ANSWER

QUESTION 17a

We were given the relation, [tex]y=15x[/tex], where y represents the number of new vocabularies learned, and x represents the number of weeks

Draw a horizontal line for number of weeks and a vertical line for number of vocabulary words using a scale of 5 units on both axes.

To graph this equation we need at least three points,

When

[tex]x=0[/tex], [tex]y=15(0)[/tex], [tex]\Rightarrow y=0[/tex]

So we plot the point [tex](0,0)[/tex]

When

[tex]x=1[/tex], [tex]y=15(1)[/tex], [tex]\Rightarrow y=15[/tex]

So we plot the point [tex](1,15)[/tex]

When

[tex]x=2[/tex], [tex]y=15(2)[/tex], [tex]\Rightarrow y=30[/tex]

So we plot the point [tex](2,30)[/tex]

Using a straight edge we draw a straight line through these three points.

The equation of the line is of the form [tex]y=mx[/tex], where [tex]m=15[/tex] is the slope.

This tells us that the 15 new vocabulary words are learned each week.

QUESTION 17 B

To find the number of new vocabulary words learnt after 5 weeks, we plug in [tex]x=5[/tex] in to the equation.

[tex]y=15(5)[/tex]

This gives us

[tex]y=75[/tex]

Therefore after 5 weeks, you learn 75 new vocabulary words.

QUESTION 17 C

We  find the number of vocabulary words learned after 4 weeks and subtract it from the number of vocabulary words learned after 6 weeks'

To find the number of new vocabulary words learnt after 4 weeks, we plug in [tex]x=4[/tex] in to the equation.

[tex]y=15(4)[/tex]

This gives us

[tex]y=60[/tex]

Therefore after 4 weeks, you learn 60 new vocabulary words.

To find the number of new vocabulary words learnt after 6 weeks, we plug in [tex]x=6[/tex] in to the equation.

[tex]y=15(6)[/tex]

This gives us

[tex]y=90[/tex]

Therefore after 6 weeks, you learn 90 new vocabulary words.

We now subtract to get

[tex]90-60=30[/tex]

Therefore you learn 30 more vocabulary words after 6 wees than after 4 weeks.

The given equation y=15x + 17 represents the number of new vocabulary words you learn every week. Here, you learn 15 new words each week. You already know 17 words at the start (when x=0).

The question is asking for the interpretation of the equation y=15x + 17, which represents the number of new vocabulary words, y, that you learn after x weeks. Here, 15 is the coefficient of x, which means that you learn 15 new words per week. The number 17 is the constant term, implying that even without any weeks passing (when x=0), you already know 17 words. Thus, after one week, you would know 15*1 + 17 = 32 words, after two weeks, 15*2 + 17 = 47 words, and so on.

The probability of obtaining a grade of 'B' in the given science class, using the concept of conditional probability, is 0.320.

To find the probability of getting a grade of 'B' given that it's a science class, also known as conditional probability, we can use the following formula:

P(grade of B | science class) = (number of students with a 'B' in science) / (total number of students in the science class).

When we apply the given numbers from the tables:

(Number of students with B in science class) = 8

(Total number of Students in the science class) = (A=5) + (B=8) + (C=10) + (D=1) + (F=1) = 25

Substituting the obtained numbers in our formula, we find:

P(grade of B | science class) = 8 / 25 = 0.320

So, the probability of getting a grade of 'B' given that it's a science class is 0.320. Therefore, the answer is O 0.320.

An equation for the relationship between time and distance for each horse include the following;

horse A; y = 1/4(x).

horse B; y = 5/2(x).

In Mathematics and Geometry, a proportional relationship is a type of relationship that passes through the origin (0, 0) and produces equivalent ratios as represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) for each horse by using various data points as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k of A = 1/4 = 8/2

Constant of proportionality, k of B = 5/2 = 10/4.

Therefore, the required linear equation for horse A is given by;

y = kx

y = 1/4(x)

Answer:

0.65 miles.

Step-by-step explanation:

Dmitry runs 3.1 miles on Saturday.

He runs 2.45 miles on Sunday.

On Saturday he runs 3.1 - 2.45 = 0.65 miles farther.

Dimitry ran 0.65 miles farther on Saturday than that during Sunday.

Distance travelled in miles by Dmitry on Saturday, d₁ = 3.1 miles

Distance travelled in miles by Dmitry on Sunday, d₂ = 2.45

The difference in the distance travelled by Dimitry during Saturday and Sunday can be calculated by subtracting the distance travelled on Sunday from that during Saturday.

Subtraction is the activity or process of determining the difference between two amounts or numbers. The phrase taking away one number from another is also used to describe the act of subtracting one number from another.

So,

The difference between the distances, d = d₁ - d₂

d = 3.1 - 2.45

d = 0.65 miles
