Answer:

Well, if we consider [tex]r[/tex] as y and [tex]q[/tex] as x.

Step-by-step explanation:

So, typically, a linear function is either represented using function notation

[tex]f(x)=mx+b[/tex]

Or in slope-intercept form

[tex]y=mx+b[/tex]

This question is oddly using the variables r and q in place of y and x. If we replace them to be y and x, it will be a linear equation (because the slope is constantly changing).

But, if you aren't allowed to replace r and q to be y and x, then it isn't a linear function.

The system of inequalities that models the situation is given as follows:

Before we build the inequalities, we have to consider that the variables of the system are given as follows:

Jeremy and his dad worked at least 85 combined hours last week, hence the first inequality is:

x + y ≥ 85.

They collected a total of more than $1000 by charging $20 per hour, hence the second inequality is:

20x + 20y ≥ 1000.

20(x + y) ≥ 1000.

The minimum number of hours that each can work is of 0, that is, they cannot work a negative number of hours, hence the constraints are:

Answer:

its 3 because 4^-n=1/256

We move all terms to the left:

4^-n-(1/256)=0

We add all the numbers together, and all the variables

-n+4^-(+1/256)=0

We add all the numbers together, and all the variables

-1n-(+1/256)=0

We get rid of parentheses

-1n-1/256=0

We multiply all the terms by the denominator

-1n*256-1=0

We multiply elements

-256n-1=0

We move all terms containing n to the left, all other terms to the right

-256n=1

n=1/-256

n=-1/256

The simplified solution for B in the equation -4 ( - 6 - b) = 1/3 (B + 16) is B = 56 + 12b

Given,

The equation: - 4 (- 6 - b) = 1/3 (B + 16)

We have to simplify the equation and find B.

Lets simplify:

-4 ( - 6 - b) = 1/3 (B + 16)

Here,

(- 4 × - 6) - 4 × - b = 1/3 × B + 1/3 × 16

24 + 4b = B/3 + 16/3

24 + 4b = (16 + B) / 3

Multiply 3 to both sides:

(24 + 4b) × 3 = (16 + B) × 3 / 3

72 + 12b = 16 + B

Add -16 to both sides:

72 + 12b - 16 = 16 + B - 16

Then,

B = 72 + 12b - 16

B = 56 + 12b

That is, the simplified solution for B in the equation -4 ( - 6 - b) = 1/3 (B + 16) is B = 56 + 12b

A number line and expression show how to find the distance from 4 to 1 is: B. A number line from -5 to 5 and two points on 1 and 4.

A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used to determine the difference between two numbers such as 4 and 1. Also, a number line typically increases in numerical value towards the right and decreases in numerical value towards the left.

In this context, we can reasonably infer and logically deduce that number line C shows the distance from 4 to 1.

Interpolation is the process of foretelling the value of a function f at a location inside the observed range of values for and. Predicting the value of y when it is outside the range indicated by the points and areas where the values and have been observed is known as extrapolation.

The values for two different numerical variables are represented by dots in a scatter plot (also known as a scatter chart or scatter graph). Each dot's location on the horizontal and vertical axes represents a data point's values. To view relationships between variables, utilize scatter plots.

Interpolation is the process of foretelling the value of a function f at a location inside the observed range of values for and. Predicting the value of y when it is outside the range indicated by the points and areas where the values and have been observed is known as extrapolation.

Balance of Kevin after 1 quarter will be 1.0055(x)

Compound interest is interest that is calculated using both the starting amount and the interest that has accrued over time.

Interest is considered to be compounded quarterly if it is compounded four times each year.

If interest is compounded four times or quarterly each year, the formula for the amount at time t is as follows.

A = P( ( 1 + (r/4))⁴ⁿ

A = Accumulated amount

P= Principal amount

r = interest rate

n = time

Given that Kevin has x dollars in an account that pays 2.2% interest, compounds quarterly

∴ P = x

r = 2.2% = 2.2/100

To find balance after one quarter , i.e. time n = 1/4 year

⇒ Balance = accumulated amount  =$  x(1 + 2.2/400)¹  = $ 1.0055(x)

Therefore, Balance of Kevin after 1 quarter will be 1.0055(x)

Slope of AB = 2; Slope of DC = 2

Slope of AD = -1/2; Slope of BC = -1/2

Both pairs of opposite sides are parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.

A parallelogram is a quadrilateral that has two pairs of opposite sides that have the same lengths and are parallel to each other.

Since the opposite sides of a parallelogram are parallel, therefore, they have the same slope value.

Slope = change in y / change in x.

Find the slope of AB and DC. then AD and BC:

Slope of AB = (-2 - 2)/(-3 -(-1)) = -4/-2

Slope of AB = 2

Slope of DC = (-3 - 1)/(-1 - 1) = -4/-2

Slope of DC = 2

Slope of AD = (-3 -(-2))/(-1 -(-3)) = -1/2

Slope of AD = -1/2

Slope of BC = (2 - 1)/(-1 - 1) = 1/-2

Slope of BC = -1/2

Therefore, since AB and DC have the same slope, they are parallel, so also is AD and BC parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.

Answer:

x = 37 , ∠ P = 17° , ∠ Q = 126° , ∠ R = 37°

Step-by-step explanation:

the sum of the 3 angles in Δ PQR = 180°

sum the 3 angles and equate to 180

x + x - 20 + 3x + 15 = 180

5x - 5 = 180 ( add 5 to both sides )

5x = 185 ( divide both sides by 5 )

x = 37

Then

∠ P = x - 20 = 37 - 20 = 17°

∠ Q = 3x + 15 = 3(37) + 15 = 111 + 15 = 126°

∠ R = x = 37°

The three sides need to add up to 23 (the perimeter is given as 23)

Givens

The sides are

Solution

x + x + 3 + 2x = 23                   Combine

4x + 3 = 23                               Subtract 3 from both sides

4x + 3-3 = 23-3                         Combine

4x = 20                                      Divide  by 4

4x/4 = 20/4

x = 5

The three sides of a triangle is x, x+3 and 2x. If the perimeter is 23 feet. Find the value of x.

In this question we are given

We are asked to calculate the value of x.

To solve this problem first we have to form an equation.

Let us solve this question.

We know that the perimeter of a triangle is the sum of all three sides.

According To Question

x + x + 3 + 2x = 23

→ 2x + 3 + 2x = 23

→ 4x + 3 = 23

→ 4x = 23 - 3

→ 4x = 20

→ x = 20/4 = 5

x = 5

The value of x is 5.

Answer: 3.3%

Step-by-step explanation:

Principal not given.

SI = PRT/100

CI = P(1+R/100)^T -

SI + CI = 85470

[P×7×2]//100 + P [1+ (7/100)]^2 = 85470

on solving: P = 3,00,000

P = 300000 SI for 2 years = 42000

CI = Rs 43470

The difference= Rs 1470

I don't know what the dropdown menus are, but Mike is half-correct. The opposite of a number is the number with the opposite sign, so the opposite of 5 is -5. But the absolute value of a number is its distance from zero on a number line, and distances can't be negative, so the absolute value of 5 is 5, not -5.

The coordinates of the point of intersection is equal to (3, 5).

In Mathematics, a point of intersection can be defined as the location on a graph where two (2) lines intersect, meet, or cross each other, which is typically represented as an ordered pair containing the point, x-axis and y-axis.

Next, we would solve the given equations simultaneously to determine the coordinates of the point of intersection as follows:

y = 1 - 2x

y = x - 5

Re-arranging the equation, we have:

y + 2x = 1

y - x = -5

Subtracting, we have:

3x = 6

x = 6/2

x = 3.

For y-coordinate, we have:

y + 2x = 1

y + 2(3) = 1

y + 6 = 1

y = 1 - 6

y = -5.

From inspection of the graph, when the number of coils is 10, the length of the spring is between 0 cm and 20 cm.

Substitute n = 10 into the equation of each given answer option:

[tex]\begin{aligned}\textsf{Option A}: \quad P(10)&=10^2+4.3\\ & =100+4.3\\&=104.3\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Option B}: \quad P(10)&=10^2-0.3(10)+4.3\\ & = 100-3+4.3\\&=97+4.3\\&=101.3\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Option C}: \quad P(10)&=0.24(10^2)+4.3\\&=0.24(100)+4.3\\&=24+4.3\\&=28.3\end{aligned}[/tex]
