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.
What is the definition of a linear function in slope-intercept format?A linear function, in slope-intercept format, is modeled as follows:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, the function is:
y = 2/3x + 1.
Then, form item a, we have that:
The slope is of m = 2/3.The intercept is of b = 1.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.

What is basic algebra ?Algebra is a branch of mathematics that facilitates the description of problems or situations into mathematical statements. It involves variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division to generate a valid mathematical statement. All branches of mathematics, such as coordinate geometry, calculus, and trigonometry, employ algebra. An elementary algebraic formula is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations on variables and constants, such as addition, subtraction, multiplication, division, etc., are done.

In a factory, the production hours t and output y are having linear relationship. When the
factory operates for 5 hours per day, it may have the number of outputs of 2000 units and 3500
units for 8 hours of operation.
(a) Model an equation that gives the outputs, y, in terms of operation hours, t, per day.
(b) If the factory wants to have 4500 units of production per day, how long it should operate?
(c) Draw the graph in excel of the production against operation hours t up to first 20 hours.
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.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).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.

4.) Estimate the total cost of groceries if the prices are $6.47, $14.72, $7.99, $9.40, and $2.79.
Round each to the nearest dollar and add.
1) Using order of operations, the solution to the given expression is; 12
2) The estimated cost of groceries if the prices are estimated to the nearest dollar is; $42
How to use order of operations?In mathematics , the acronym for the right order of operations is PEMDAS which denotes;
P- Parentheses
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction.
3) From the given statement, we are to add 6 to 12, then divide the sum by 4. Thereafter, we divide the quotient by negative nine and then multiply by twenty-four. This is expressed as;
[(6 + 12)/4] = 18/4 = 9/2
Then divide by -9 to get;
(9/2) ÷ 9 = 1/2
Then we multiply by 24 to get;
1/2 * 24 = 12
4) Let us first estimate each cost to the nearest dollar to get;
$6.47 ≈ $6
$14.72 ≈ $15
$7.99 ≈ $8
$9.40 ≈ $9
$2.79 ≈ $3
Total estimated cost = 6 + 15 + 8 + 9 + 3 = $42

280Joules of work is done pushing a bike 35m. How much force was used to push the bike?
By definition, the work is given by:
[tex]W=F\cdot d\text{.}[/tex]Where W is the work in Joules (J), F is the force in Newtons (N) and d is the distance in meters (m).
In this problem we have:
• W = 280J,
,• d = 35m.
We can find the force F in terms of W and d:
[tex]F=\frac{W}{d}\text{.}[/tex]Replacing the values of W and d, we find that the force F is:

The table represents a quadratic function. Write an equation of the function in
standard form.
X- -3,-2,-1,0
An equation of the function in standard form for the given table of values is equal to -2x² - 7x - 6 = 0.
The standard form of a quadratic equation.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

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
