Multiply 5c(9 − 4c).

The equation for the line of best fit where x represents the month and y represents the time is: y = −2.14x + 45.

In order to determine a linear equation of the line of best fit (trend line) that models the data points contained in the table, we would have to use a scatter plot.

In this scenario, the number of months would be plotted on the x-axis of the scatter plot while the time (minutes) would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line on the scatter plot.

From the scatter plot (see attachment) which models the relationship between the number of months and time in the table, a linear equation of the line of best fit is given by:

y = -2.14x + 45

The function y = 7|x + 1| - 5 can be written as a Piecewise Function as follows,

               7x + 2                for x > -1

y   =

              -7x - 12               for x < -1

Given, a function y = 7|x + 1| - 5

Now, we have to write the given function as a piecewise function

|x + 1| = (x + 1) for x > -1 and

|x + 1| = - (x + 1) for x < -1

So, the given function can be written as a piecewise function

               7(x + 1) - 5                for x > -1

y   =

              -7(x + 1) - 5                for x < -1

On simplifying, we get

               7x + 2                for x > -1

y   =

              -7x - 12               for x < -1

Hence, the given function y = 7|x + 1| - 5 can be written as a Piecewise Function as follows,

Answer:

9/40 of the book was left to read

Step-by-step explanation:

Required to find the fraction of remainder of the book:

first we need to find the (LCM) lowest common multiple so both fractions can have common denominator in order to complete addition or subtraction.

[tex] \frac{3}{8 } + \frac{2}{5} [/tex]

Look at the denominators, we see there is 8 and 5 so that means we have to list the multiples of both numbers until a common is found.

multiples of:

8 = 8, 16, 24, 32, 40

5 = 5, 10, 15, 20, 25, 30, 35, 40

from this we can distinguish that the LCM is 40.

Next we need to multiply each numerator of the fraction by the number of times it took for the denominator to reach the LCM.

It took 8 five multiples to reach the LCM so therefore its new numerator will be 3×5 = 15

[tex] \frac{5}{8} to \: give \frac{15}{40} [/tex]

It took 5 eight multiples to reach the LCM so therefore its new numerator will be 2×8 = 16

[tex] \frac{2}{5} to \: give \: \frac{16}{40} [/tex]

finally we can add but values together and subract from the whole to find the remainder.

[tex] \frac{15}{40} + \frac{16}{40} = \frac{31}{40} [/tex]

in total she read 31/40 of the book.

[tex] \frac{40}{40} - \frac{31}{40} = \frac{9}{40} [/tex]

and the remainder which she did not read was 9/40

This means that the answer is D.

In everyday speech, the term "probability" refers to the likelihood that a specific event (or set of events) will take place, expressed as a number between 0 and 100% or as a linear scale from 0 (impossibility) to 1 (certainty). Statistics is the study of occurrences that follow a probability distribution.

The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

According to the given question:-

Even though there aren't any actual options for this question, figuring out the right response should be simple. The quantity of numbers that will be listed is the "probability of success" that is being discussed here.

In the given question,

We have to find the value of x and y.

It is also given that the given quadrilateral is a parallelogram.

Since the given quadrilateral is a parallelogram so the opposite sides and opposite angles are equal to each other.

So 4x−17=2x−1......................(1)

5y−13=3y+5...............(2)

Simplifying equation 1 to find the value of x

4x−17=2x−1

Add 17 on both side

4x−17+17=2x−1+17

Simplifying

4x=2x+16

Subtract 2x on both side

4x−2x=2x+16−2x

Simplifying

2x=16

Divide by 2 on both side

2/2 x = 16/2

x=8

Hence, the value of x is 8.

Now finding the value of y by solving the equation 2

5y−13=3y+5

Add 13 on both side

5y−13+13=3y+5+13

Simplifying

5y=3y+18

The major thing that Ryan should be worried about is the C) high annual depreciation.

Normally, when we buy cars they have so much value but when the cars start being used more often, they tend to depreciate in value due to wear and tear and second value of the product. This tells us that when a car is driven for more miles in a year, it will depreciate greatly.

We are told that Ryan plans to drive about 40 miles to work and back everyday which means that in a year he would have driven thousands of miles. This will lead to a high depreciation.

The formula for the final cost, in terms of the original price y, is:

c(y) = y*(0.88)*(1.03)

Let's define y as the original price of the DVD.

We first apply a discount of the 12% of the price, so the new cost will be:

c(y) = y*(1 - 12%/100%)

c(y) = y*(1 - 0.12)

Then we apply a tax of the 3%, this in increase, then we can write this as:

c(y) = y*(1 - 0.12)*(1 + 3%/100%)

c(y) = y*(1 - 0.12)*(1  + 0.03)

c(y) = y*(0.88)*(1.03)

Answer:

(- 4, 29 ) and ( [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex] )

Step-by-step explanation:

7x + y = 1 ( subtract 7x from both sides )

y = 1 - 7x → (1)

2x² - y = 3 → (2)

substitute y = 1 - 7x into (2)

2x² - (1 - 7x) = 3

2x² - 1 + 7x = 3

2x² + 7x - 1 = 3 ( subtract 3 from both sides )

2x² + 7x - 4 = 0 ← in standard form

(x + 4)(2x - 1) = 0 ← in factored form

equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

substitute these values into (1) for corresponding values of y

x = - 4 : y = 1 - 7(- 4) = 1 + 28 = 29 ⇒ (- 4, 29 )

x = [tex]\frac{1}{2}[/tex] : y = 1 - 7([tex]\frac{1}{2}[/tex] ) = 1 - [tex]\frac{7}{2}[/tex] = - [tex]\frac{5}{2}[/tex] ⇒ ([tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex] )

If 2 angles are supplementary, then they form a straight angle.

Supplementary angles are angles whose measures add to 180º, and straight angles are angles with measure of 90º. The converse is false, as 100º and 80º, for example, are supplementary angles, but do not form a straight angle.

For statement 2, the converse statement is:
