For the linear function y = 2/3x + 1, we have that:

a) The slope is of 2/3 and the intercept is of 1.

b) The y-intercept is marked at y = 1 on the y-axis.

c) Using the slope and the intercept, point (3,3) is the second point used to graph the function.

d) The graph of the linear function y = 2/3x + 1 is given at the end of the answer.

A linear function, in slope-intercept format, is modeled as follows:

y = mx + b

In which:

For this problem, the function is:

y = 2/3x + 1.

Then, form item a, we have that:

For item b, the y-intercept of b = 1 means that the function crosses the y-axis at b = 1.

For item c, we have to consider that the slope is of 2/3, meaning that when y increases by 2, x increases by 3. Point (0,1) is on the graph of the function, hence point (3,3) will also be, as x increases by 3 from 0 to 3 and y increases by 2 from 1 to 3.

Considering the discussion above, the graph of the function is given at the end of the answer, with the intercept and point (3,3) labeled.

Measure of the angle m ∠ RQS = 58 ° for the given circle with arc RS subtending m ∠RPS=14 x + 46 ° at the center P and m ∠ RQS = 3 x + 43 ° at Q, on the circumference.

As given in the question,

Measure of the angle is given by :

m ∠ RPS=14 x + 46 °                                  

m ∠ RQS=3 x + 43 °                                      

m ∠ RPS = twice m ∠RQS (angle subtended at center of the circle)

14 x +46 =2(3 x + 43)

⇒ 14x + 46 = 6x +86

⇒ 14x-6x=86-46

⇒8x=40

⇒ x=5°

m ∠ RQS = (3 x + 43) °  

                 =[3(5) + 43 ]°

                 = 58°

Therefore, measure of the angle in the given circle m ∠RQS is equal to the  58 °

The degree of the polynomial is even.

Algebraic expressions called polynomials include indeterminates and constants. Polynomials can be considered a particular type of mathematics. In practically all areas of mathematics, including calculus, they are used to express numbers. They are also regarded as being crucial in several areas of mathematics. Examples of polynomials include 2x + 9 and [tex]x^{2}[/tex] + 3x + 11. The "=" sign is absent from all of these samples, as you may have observed.

The polynomial's degree is even since the final behavior is the same in both directions (for -x and for +x, y→∞).

The y-intercept is the fixed term. Since it is not an integer, evenness and oddness cannot be determined.

The total number of 8780 minutes was spent on the assembly and packaging of the wagons in June at these two stores.

Matrix A shows the number of wagons sold at two different locations during the month of June.

[tex]A =\begin{bmatrix}50 & 90 & 30\\25 & 5 & 50\\\end{bmatrix}[/tex]

Matrix B shows the number of minutes required for the assembly and packaging of the three different-sized wagons.

[tex]B = \begin{bmatrix}15 & 5\\20 & 8 \\30 & 12 \end{bmatrix}[/tex]

We have to multiply Matrix A by Matrix B

[tex]AB =\begin{bmatrix}50 & 90 & 30\\25 & 5 & 50\\\end{bmatrix}\begin{bmatrix}15 & 5\\20 & 8 \\30 & 12 \end{bmatrix}[/tex]

[tex]AB =\begin{bmatrix}3450 & 1330 \\2875 & 1125 \\\end{bmatrix}[/tex]

So the time is 3450 + 1330 + 2875 + 1125 = 8780 minutes

Therefore, a total number of 8780 minutes was spent on the assembly and packaging of the wagons in June at these two stores.

Answer:

  the slope is 3/4

  the y-intercept is 4

Step-by-step explanation:

You want the slope and y-intercept of the line defined by the equation 3x -4y = -16.

The values of interest can be found easily from the slope-intercept form of the equation of the line. Solving for y puts the equation in that form.

  3x -4y = -16 . . . . . . given

  -4y = -3x -16 . . . . . subtract 3x

  y = 3/4x +4 . . . . . . divide by -4

Compare this to the slope-intercept form equation:

  y = mx + b . . . . . . . line with slope m and y-intercept b

We see that ...

  m = 3/4, b = 4

  The slope is 3/4

  The y-intercept is 4

It takes four (4) comedy routines to hear 360 jokes

A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

By applying direct proportion, we have:

1 minute = 3 jokes

X minutes = 360 jokes

Cross-multiplying, we have:

3X = 360

X = 360/3

X = 120 minutes

Now, we can determine the number of comedy routines required for 360 jokes as follows:

Number of comedy routines = 120/35

Number of comedy routines = 3.42 ≈ 4 comedy routines.

Considering the linear relationship between the variables, we have that:

a) The function is: y = 500t - 500.

b) The factory should operate for 10 hours to have a production of 4500 units.

c) The graph for the first 20 hours of the function is given at the end of the answer.

A linear function, in slope-intercept format, is modeled according to the following rule:

y = mx + b

In which:

For the given linear relationship, we have two points, as follows:

(5,2000) and (8,3500).

The slope is given by change in y divided by change in x, hence:

m = 1500/3 = 500.

Then:

y = 500t + b.

When t = 5, y = 2000, hence we solve for the intercept as follows:

2000 = 500(5) + b

b = -500.

Then the function is:

y = 500t - 500.

For 4500 units, the time is found as follows:

4500 = 500t - 500

500t = 5000.

t = 5000/500

t = 10 hours.

An equation of the function in standard form for the given table of values is equal to -2x² - 7x - 6 = 0.

In Mathematics, the standard form of a quadratic equation is given by;

y = f(x) = ax² + bx + c = 0

In order to write an equation of the quadratic function in standard form, we would formulate a system of equations from the data provided in the table above as follows:

-6 = a(-3)² + b(-3) + c  ⇒ -6 = 9a - 3b + c      .......equation 1.

0 = a(-2)² + b(-2) + c  ⇒   0 = 4a - 2b + c      .......equation 2.

-2 = a(-1)² + b(-1) + c  ⇒   -2 = a - b + c          .......equation 3.

From equation. 2, we derive:

c = -4a + 2b   .....equation 4.

Substituting equation 4 into equation 1 and 3, we derive the following equations:

-2 = a - b - 4a + 2b          ⇒ -2 = -3a + b

-6 = 9a - 3b - 4a + 2b     ⇒ -6 = 5a - b

By using the elimination method, the value of a is given by:

[-2 + (-6) = (-3a + 5a) + (b + (-b)]

-2 - 6 = -3a + 5a + b - b

-8 = 2a

a = -4

Next, we would determine the value of b as follows:

-2 = -3a + b

b = -2 + 3a

b = -2 + 3(-4)

b = -2 - 12

b = -14

For the value of c, we have:

c = -4a + 2b

c = -4(-4) + 2(-14)

c = 16 - 28

c = -12.

Substituting the respective values of a, b and c into the standard form of a quadratic equation:

ax² + bx + c = 0

-4x² - 14x - 12 = 0

Dividing all through by 2, we have the following quadratic function:

-2x² - 7x - 6 = 0
