Step-by-step explanation:

Miguel started running, and he runs 1 mile in the first week, then the equation will be y = 2x + 1. Hence, option A is correct.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given information in the question,

Miguel runs for 1 mile in the first week.

Then, his goal is to run 2 miles farther than his distance for the previous week.

Then the equation will be: y = 2x + 1

Here, y is the total distance and x is the number of miles.

Step-by-step explanation:

Let x be the number of students in the class

12% failed and the number of students is 3

x*12% = 3

x*.12 = 3

Divide each side by .12

x * .12 /.12 = 3/.12

x =25

Answer:

25 students.

Step-by-step explanation:

12% is 3 students.

100% is the number of students in the class.

3 times 100 divided by 12 is 25.

So there are 25 students in the class.

Step-by-step explanation:

y = k*x

Where,

y = weight of a object on Jupiter

x = weight of the object on earth

k = constant of proportionality

An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.

y = k*x

378.2 = k*150

378.2 = 150k

k = 378.2/150

= 2.5213

Approximately k = 2.52

determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth

y = k*x

12.64 = 2.52*x

12.64 = 2.52x

x = 12.64 / 2.52

= 5.0159

Approximately x = 5.02 pounds

a) F = (9/5)*C + 32

b)

c) The graph can be seen below, it is a linear function.

We have the formula:

C = (5/9)*(F - 32)

To solve it for F, we need to isolate the F in the formula:

F = (9/5)*C + 32

b) Now we want to convert some temperatures.

If C = 0° celcius, then:

F =  (9/5)*0 + 32 = 32

This means that: 0°C = 32°F

if C = 20° Celcius, then:

F =  (9/5)*20 + 32 = 68

then 20°C = 68°F

if C = 32°C then:

F = (9/5)*32 + 32 = 89.6°

So 32°C = 89.6°F

Finally, if C = 41°C then:

F = (9/5)*41 + 32 = 105.8

Then 41°C = 105.8°F

c)  Here the function is:

F = (9/5)*C + 32

This clearly is a linear function, and the graph can be seen in the image below.

If I'm correct, it's going to be x > -3

Answer:

1.7 miles

Step-by-step explanation:

Pythagoras' Theorem sets the relation between three sides of a right-angled triangle. The distance between Raoul's home and the library is 1.3 miles.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|² = |AB|² + |BC|²    

where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).

The school is located 0.5 miles east of Raoul's house. The library is located 1.2 miles south of the school. Therefore, the distance between the home and the library is the hypotenuse of the triangle formed.

AC² = AB² + BC²

AC² = 0.5² + 1.2²

AC = 1.3 miles

Hence, the distance between Raoul's home and the library is 1.3 miles.

Answer:

Example 1:

Find the common denominator of the fractions.

16 and 38

We need to find the least common multiple of 6 and 8 . One way to do this is to list the multiples:

6,12,18,24−−,30,36,42,48,...8,16,24−−,32,40,48,...

The first number that occurs in both lists is 24 , so 24 is the LCM. So we use this as our common denominator.

Listing multiples is impractical for large numbers. Another way to find the LCM of two numbers is to divide their product by their greatest common factor ( GCF ).

Example 2:

Find the common denominator of the fractions.

512 and 215

The greatest common factor of 12 and 15 is 3 .

So, to find the least common multiple, divide the product by 3 .

12⋅153=3 ⋅ 4 ⋅ 153=60

If you can find a least common denominator, then you can rewrite the problem using equivalent fractions that have like denominators, so they are easy to add or subtract.

Example 3:

Add.

512+215

In the previous example, we found that the least common denominator was 60 .

Write each fraction as an equivalent fraction with the denominator 60 . To do this, we multiply both the numerator and denominator of the first fraction by 5 , and the numerator and denominator of the second fraction by 4 . (This is the same as multiplying by 1=55=44 , so it doesn't change the value.)

512=512⋅55=2560215=215⋅44=860

512+215=2560+860                 =3360

Note that this method may not always give the result in lowest terms. In this case, we have to simplify.

=1130

The same idea can be used when there are variables in the fractions—that is, to add or subtract rational expressions .

Example 4:

Subtract.

12a−13b

The two expressions 2a and 3b have no common factors, so their least common multiple is simply their product: 2a⋅3b=6ab .

Rewrite the two fractions with 6ab in the denominator.

12a⋅3b3b=3b6ab13b⋅2a2a=2a6ab

Subtract.

12a−13b=3b6ab−2a6ab                   =3b − 2a6ab

Example 5:

Subtract.

x16−38x

16 and 8x have a common factor of 8 . So, to find the least common multiple, divide the product by 8 .

16⋅8x8=16x

The LCM is 16x . So, multiply the first expression by 1 in the form xx , and multiply the second expression by 1 in the form 22 .

x16⋅xx=x216x38x⋅22=616x

Subtract.

x16−38x=x216x−616x                  =x2 − 616x\

Answer:

Step-by-step explanation:

The value of x in the shape is 111

The shape is a heptagon

This is so because the shape has 7 sides

i.e. n = 7

The sum of angles in the shape is

Sum = 180(n - 2)

So, we have

Sum = 180(7 - 2)

Evaluate

Sum = 900

Also, the sum of angles in the shape is

Sum = x + 120 + 158 + 126 + 125 + 121 + 139

This gives

Sum = x + 789

So, we have

x + 789 = 900

Evaluate the like terms

x = 111

Hence, the value of x in the shape is 111

The equation of the line that passes through the point (5,3) and has a slope of -4/5 is,

⇒ 4x + 5y = 35

Here,

The given point is (5, 3) and slope is -4/5.

We have to find the equation of the line that passes through the point (5,3) and has a slope of -4/5.

What is Equation of line?

The equation of the line that passes through the point (a, b) and has a slope of m is;

⇒y - a = m (x - b)

Now,

The given point is (5, 3) and slope is -4/5.

Hence, The equation of the line that passes through the point (5,3) and has a slope of -4/5 is;

y - 3 = -4/5 (x - 5)

5 (y - 3) = -4 (x - 5)

5y - 15 = -4x + 20

4x + 5y = 20 + 15

4x + 5y = 35

Therefore, The equation of the line that passes through the point (5,3) and has a slope of -4/5 is

Answer:

x = -1, y = 4

Step-by-step explanation:

x + y = 3

-x + y = 5

This means that y = 3 - x

We can substitute this value into the equation

-x + y = 5

-x + 3 - x = 5

3 - 2x = 5

Subtract 3 from both sides

-2x = 2

Divide both sides by -2

x = -1

Plugging this number into the equation, we have:

-1 + y = 3

Add 1 to both sides

y = 4
