Riley's monthly take-home pay is $3,525. What is his safe debt load? *

Answer:

1 ≤ x ≤ 9

Step-by-step explanation:

Answer:

unit rate = $ 10 per km.

y = 10x

Step-by-step explanation:

Unit rate:

    Cost of travelling 1 km is $ 10. So, unit rate is $10

Equation:

       If 'x' km distance is travelled, then cost 'y',

              y = x * unit rate

               y = x * 10

               y = 10x

if f f(x) = ax² + bx + c for all x and if f( -3 ) = 0 and f( 1) = 0 then b + c will be either 1,-5 or 5 depending on value of c.

A relation is a function if it has only One y-value for each x-value.

Given that f(x) = ax² + bx + c for all x and

if f( -3 ) = 0 and

f( 1) = 0

We need to find the value of b+c

f(-3)=a(-3)² + b(-3) + c

f(-3)=9a-3b+c=0

9a-3b+c=0

We need to find the value of b + c, which is equal to -a.

From equation (2), we have:

a = -b - c

Substituting this value of a in equation (1), we get:

9(-b - c) - 3b + c = 0

-12b - 8c = 0

3b + 2c = 0

b = -(2/3)c

Substituting this value of b in equation (2), we get:

a + (-(2/3)c) + c = 0

a = (1/3)c

Therefore, b + c = -(2/3)c + c = (1/3)c

Hence, if f f(x) = ax² + bx + c for all x and if f( -3 ) = 0 and f( 1) = 0 then b + c will be either 1,-5 or 5 depending on value of c.

What is Period of a simple pendulum?

The formula for the period T of a pendulum is T = 2π Square root of √L/g, where L is the length of the pendulum and g is the acceleration due to gravity.

The equation relating the period T and length L of a pendulum is given by:

T = 2π√(L/32)

We can rearrange this equation to solve for L in terms of T:

L = 32(T/2π)²

To find the length of a pendulum with period 8 seconds, we can substitute T = 8 into the above equation and solve for L:

L = 32(8/2π)²

L ≈ 316 feet

Rounding this value to the nearest foot, we get:

L ≈ 316 feet (to the nearest foot)

When you create a dot plot, the operations that you have to do are:

c. Place a dot along a horizontal scale for each observation.

d. "Pile up" dots that are too close to show separately

A dot plot is a simple way of representing numerical data. It consists of a horizontal axis and a series of dots that are placed along it to represent the values of individual observations. Each dot corresponds to one observation, and its position along the axis represents its value.

Option (a) is not correct because a dot plot typically does not have a vertical axis showing frequency of observations. Option (b) is not correct because connecting adjacent dots to create a polygon is not a common practice in dot plots. Instead, each dot represents a single observation, and dots are placed along a horizontal scale to show their value. If multiple observations have the same value, they are "piled up" on top of each other to avoid overcrowding the plot.

Therefore, the correct options are (c) Place a dot along a horizontal scale for each observation and d. "Pile up" dots that are too close to show separately

The regression line can be used to determine the strength of a linear association between two variables, as well as to make predictions about the values of y for a given x-value.

The regression line is a type of mathematical model used to describe the relationship between two variables, typically denoted as x and y. The regression line is a straight line that best fits the data points of the two variables. This line can be used to make predictions about the values of y for a given x-value.

The equation of the regression line is y = mx + b, where m is the slope of the line, and b is the y-intercept. The slope of the line, m, represents the strength of the linear relationship between the two variables. It is calculated by dividing the covariance of the two variables by the variance of the independent variable (x). The y-intercept, b, is the point where the regression line crosses the y-axis. It is calculated by taking the mean of y and subtracting the slope of the line multiplied by the mean of x.

The regression line can also be used to determine the strength of the linear association between two variables. This is determined by calculating the correlation coefficient, which is a measure of how closely two variables are associated. The correlation coefficient is calculated by taking the covariance of the two variables, divided by the product of the standard deviation of each variable. A correlation coefficient of close to 1 indicates a strong positive linear association, while a correlation coefficient of close to -1 indicates a strong negative linear association.

In conclusion, the regression line can be used to determine the strength of a linear association between two variables, as well as to make predictions about the values of y for a given x-value.

Answer:

Step-by-step explanation:

x is one blanket

y in one sheet

3x+y=190

2y+x=100

y=190-3x

2y+x=100

replace the y in the second equation with the first one

2(190-3x)+x=100

380-6x+x=100

380-5x=100

-5x=100-380

-5x=-280

x= -280/-5

x=56

replace the x with 56 so you can find the y

2y+56=100

2y=100-56

2y=44

y=44/2

y=22

so one blanket is 56 and a sheet is 22

Answer:

After performing synthetic division, as the last number in the bottom row is not zero, this indicates that (x + 3) is not a factor of the given polynomial.

Step-by-step explanation:

Given polynomial function:

[tex]2x^3+7x^2+3[/tex]

To determine is (x + 3) is a factor of the given polynomial by the method of synthetic division:

Note: As the x term is missing, place a zero in its place.

[tex]\begin{array}{c|cccc}-3 &2&7&0&3\\\cline{1-1}\end{array}[/tex]

Bring the leading coefficient straight down:

[tex]\begin{array}{c|cccc}-3 &2&7&0&3\\\cline{1-1}&\downarrow&&&\\\cline{2-5}&2&&&\end{array}[/tex]

Multiply the number you brought down with the number in the division box and put the result in the next column (under the 7):

[tex]\begin{array}{c|crrr}-3 &2&7&0&3\\\cline{1-1}&\downarrow&-6&&\\\cline{2-5}&2&&&\end{array}[/tex]

Add the two numbers together and put the result in the bottom row:

[tex]\begin{array}{c|crrr}-3 &2&7&0&3\\\cline{1-1}&\downarrow&-6&&\\\cline{2-5}&2&1&&\end{array}[/tex]

Repeat:

[tex]\begin{array}{c|crrr}-3 &2&7&0&3\\\cline{1-1}&\downarrow&-6&-3&9\\\cline{2-5}&2&1&-3&12\end{array}[/tex]

The bottom row (except the last number) gives the coefficients of the quotient. The degree of the quotient is one less than that of the dividend.  The last number in the bottom row is the remainder.

Therefore, if we divide the polynomial by (x + 3) we get:

[tex]2x^2+x-3+\dfrac{12}{x+3}[/tex]

As the last number in the bottom row is not zero, this indicates that (x + 3) is not a factor of the given polynomial.

The number of pretzels in the beginning was 44 pretzels solving the equation.

An equation is a mathematical statement containing two expressions on either sides which are connected with an equal to sign.

Either sides of an equation is called as left hand side and right hand side.

Let the total number of pretzels = x

Pretzels has been spilled and lost half of the pretzels.

Remaining pretzels = x - x/2

Jane ate 14 pretzels.

Remaining pretzels = x - x/2 - 14

Her sister then ate one more than half the remaining pretzels.

Remaining pretzels = x - x/2 - 14 - [1/2 (x - x/2 - 14) + 1]

Remaining pretzels is 3.

So we get an equation,

x - x/2 - 14 - [1/2 (x - x/2 - 14) + 1] = 3

Solve for x.

x - x/2 - 14 - (x/2 - x/4 - 7 + 1) = 3

x - x/2 - x/2 + x/4 - 14 + 7 - 1 = 3

x/4 - 7 - 1 = 3

x/4 - 8 = 3

x/4 = 11

x = 44
