Answer:

3 nights

Step-by-step explanation:

Set up an equation that represents the problem:

y = 1.25x + 3.95

Where y is the total cost and x is the number of additional nights you rent the movie

Substitute:

7.70 = 1.25x + 3.95

Subtract 3.95 on both sides:

7.70 = 1.25x + 3.95

-3.95              -3.95

3.75 = 1.25x

Divide by 1.25 on both sides:

3.75 = 1.25x

/1.25    /1.25

3 = x

Therefore, you kept the movie for 3 additional nights.

Here in question, the table is not given to complete the table with ordered pairs. So, in general, found the possible integer ordered pairs to create the table as in attached figure are [tex](x,y) =(0,3), (12,0),(4,2),(8,1)[/tex].

Step-by-step explanation:

We have the following given linear equation : [tex]x+4y = 12[/tex].Let's find out ordered pairs that satisfies this linear equation .

At x=0 ,

[tex]0 + 4y = 12 \\4y=12\\y=3[/tex]

So, one pair is [tex](x,y) = (0,3)[/tex].

Similarly, At y=0,

[tex]x +4.0 = 12\\x=12[/tex]

SO, another pair is [tex](x,y) = (12,0)[/tex].

At x=4,

[tex]4+4y=12\\4y=8\\y=2[/tex]

Pair is [tex](x,y) = (4,2)[/tex].

At x=8,

[tex]8+4y=12\\4y=4\\y=1[/tex]

Pair is [tex](x,y) = (8,1)[/tex].

Therefore all the possible integer ordered pairs are [tex](x,y) =(0,3), (12,0),(4,2),(8,1)[/tex].

A convex polygon with n + 2 sides has the sum of its interior angles equal to 2160 degrees, which is 360 degrees more than a polygon with n sides that has 1800 degrees.

The degree measure of the sum of the interior angles of a convex polygon with n sides, given as 1800 degrees, follows the formula (n - 2) times 180 degrees. For a convex polygon with n + 2 sides, we can apply the same formula: ((n + 2) - 2) times 180 = (n times 180) + (2 times 180).

Therefore, the degree measure of the sum of the interior angles of a convex polygon with n + 2 sides is 1800 degrees plus 360 degrees, giving us a total of 2160 degrees.

Answer:

Step-by-step explanation:

Given that the functions f and g are defined by

[tex]f(x)=2x^2+x-3[/tex] and [tex]g(x)=x-1[/tex]

To find (f-g)(x)

Substitute the values of the functions we get

[tex](f-g)(x)=f(x)-g(x)=2x^2+x-3-(x-1)[/tex]

[tex]=2x^2+x-3-1(x)-1(-1)[/tex]

[tex]=2x^2+x-3-x+1[/tex]

[tex]=2x^2-2[/tex] ( by adding the like terms )

The value of (f-g)(x) is [tex]2x^2-2[/tex]. Thus, the correct option is (D)

Two different functions are given that are as follow:

[tex]f(x)=2x^2+x-3[/tex]

[tex]g(x)=x-1[/tex]

We need to determine the value of the composite function that is (f-g)(x).

Now, by using the property of the composite function (f-g)(x) can also be written as:

[tex](f-g)(x)=f(x)-g(x)[/tex]

Substitute the values of both the functions and solve it further for (f-g)(x).

[tex]\begin{aligned}(f-g)(x)&=(2x^2+x-3)-(x-1)\\&=2x^2+x-3-x+1\\&=2x^2-2\\&=2(x^2-1)\end{aligned}[/tex]

Thus, the value of (f-g)(x) is [tex]2x^2-2[/tex]. Thus, the correct option is (D)

The measure of angle B is 65°

Explanation:

Given that ∠A and ∠B are supplementary angles.

The measures are ∠A = (3x - 17)° and ∠B = (2x-23)°

The value of x:

Since, supplementary angles add up to 180°, then we have,

[tex]\angle A+ \angle B=180^{\circ}[/tex]

Substituting the values, we have,

[tex]3x-17+2x-23=180[/tex]

               [tex]5x-40=180[/tex]

                       [tex]5x=220[/tex]

                        [tex]x=44[/tex]

Thus, the value of x is 44

Measure of angle B:

Let us determine the measure of angle B by substituting the value of x in ∠B = (2x-23)°

Thus, we have,

[tex]\angle B=(2(44)-23)^{\circ}[/tex]

[tex]\angle B=(88-23)^{\circ}[/tex]

[tex]\angle B=65^{\circ}[/tex]

Thus, the measure of angle B is 65°

Answer:

There are many fractions that are equivalent to 8/12. But if you are looking for the most simplified fraction, then the answer would be 2/3. Because you divide 8 and 12 both by 2. 8 divided by 2 equals 4, and 12 divided by 2 equals 6. Then you would do it again, since both can be divided by 2 again. 4 divided by 2 equals 2, and 6 divided by 2 equals 3. You cannot divide 3 by 2, so your answer would be 2/3.

Answer:

D)M(x)=70x

Step-by-step explanation:

The function that represents the remaining distance after x hours is M(x) = 617 - 70x (option C).

The question asks about the function that represents the number of remaining miles, M(x), Kyle has to travel after x hours at a speed of 70 miles per hour. To calculate the remaining distance, we subtract the distance traveled (70 miles per hour times x hours) from the total distance of the trip, which is 617 miles. Therefore, the correct function is M(x) = 617 - 70x, which corresponds to option C.

To further illustrate this with an example, if Kyle drives for 1 hour at 70 miles per hour, he would have traveled 70 miles, so the remaining distance would be M(1) = 617 - 70(1) = 547 miles.

Miss C weight before she started her diet is 80 kg.

Solution:

Weight before diet = x

Weight loss percent = 8%

Present weight of Miss C = 73.6 kg

[tex]$ x-x\times \ 8 \% =73.6[/tex]

[tex]$ x-x\times \frac{8}{100} =73.6[/tex]

The denominators must be same to add/subtract the fractions.

LCM of 1 and 100 = 100

Multiply first term by [tex]\frac{100}{100}[/tex] and 73.6 by [tex]\frac{100}{100}[/tex] to make the denominator same.

[tex]$ \frac{100x}{100} - \frac{8x}{100} =\frac{7360}{100}[/tex]

[tex]$ \frac{100x-8x}{100} =\frac{7360}{100}[/tex]

Multiply by 100 on both sides, we get

100x - 8x = 7360

92x = 7360

Divide by 92 on both sides, we get

x = 80

Miss C weight before she started her diet is 80 kg.

The equation of the line is [tex]y=\frac{1}{4}x-\frac{29}{7}[/tex]

Explanation:

The equation of the line is perpendicular to [tex]y=-14 x-8[/tex]

The equation is of the form [tex]y=mx+b[/tex] where m=-14

Slope:

The slope of the perpendicular line can be determined using the formula,

[tex]m_1 \cdot m_2=-1[/tex]

[tex]-14 \cdot m_2=-1[/tex]

       [tex]m_2=\frac{1}{14}[/tex]

Thus, the slope of the line is [tex]m=\frac{1}{14}[/tex]

Equation of the line:

The equation of the line can be determined using the formula,

[tex]y-y_1=m(x-x_1)[/tex]

Substituting the slope [tex]m=\frac{1}{14}[/tex] and the point (2,-4), we get,

[tex]y+4=\frac{1}{14}(x-2)[/tex]

Simplifying, we get,

[tex]y+4=\frac{1}{14}x-\frac{1}{7}[/tex]

     [tex]y=\frac{1}{14}x-\frac{1}{7}-4[/tex]

     [tex]y=\frac{1}{4}x-\frac{29}{7}[/tex]

Thus, the equation of the line is [tex]y=\frac{1}{4}x-\frac{29}{7}[/tex]

Step-by-step explanation:

There was a minor mistake in the second step. The sum should be 2/3 + 4/9, not 2/9 + 4/9. After finding the common denominator and converting the fractions, we add the numerators to get 10/9, which simplifies to 1 1/9.

The process Rodrigo followed is correct, but there was a small mistake in the second step. Here, the problem should be 2/3 + 4/9, not 2/9 + 4/9. To add fractions like this, it's critical to ensure they have common denominators. The lowest common denominator (LCD) of 3 and 9 is 9.

So, the fraction 2/3 should be converted to its equivalent fraction with 9 as the denominator. Multiplying both the numerator and the denominator of 2/3 by 3, we get 6/9. So now our problem becomes 6/9 + 4/9.

Now, we can add them by combining their numerators: 6+4 = 10. So, the answer would be 10/9. But in simplest form, we would write this as 1 1/9. Hence, the sum of 2/3 and 4/9 in simplest terms is 1 1/9.

To find out what percent 9 is of 20, we can use the formula part/whole = percent/100. Using this equation, we can solve for p and find that 9 is 45% of 20.

To find out what percent 9 is of 20, we can set up an equation using the formula:

part/whole = percent/100

In this case, the part is 9, the whole is 20, and we want to find the percent. So the equation becomes:

9/20 = p/100

To solve for p, we can cross multiply:

9 * 100 = 20 * p

Dividing both sides of the equation by 20 gives us:

900 = 20p

Finally, dividing both sides by 20 gives us the value of p:

p = 900/20 = 45

Therefore, 9 is 45% of 20.
