A linear function has an x-intercept of 12 and a slope of 3/8. How does this function compare to the linear function that is represented by the table?
Answer:
We rewrite the statement correctly:
"A linear function has an y-intercept of 12 and a slope of 3/8"
Therefore, the linear function is:
y = (3/8) x + 12
We look for the linear function of the table:
y-yo = m (x-xo)
Where,
m = (y2-y1) / (x2-x1)
m = ((- 3/8) - (- 3/4)) / ((1/3) - (- 2/3))
m = ((- 3/8) - (- 6/8)) / (3/3)
m = ((- 3 + 6) / 8) / (1)
m = 3/8
(xo, yo) = (- 2/3, -3/4)
Substituting:
y + 3/4 = (3/8) (x + 2/3)
y = (3/8) x + 2/8 - 3/4
y = (3/8) x + 1/4 - 3/4
y = (3/8) x + -2/4
y = (3/8) x + -1/2
The lines are:
y = (3/8) x + 12
y = (3/8) x + -1/2

How do you graph 2/5 on a number line
To graph 2/5 on a number line, divide the number line into equal segments and locate the point that represents 2/5.
Explanation:To graph 2/5 on a number line, divide the number line into equal segments and find the point that represents 2/5. Start by labeling the endpoints of the number line with the corresponding values. In this case, you can label 0 on the left and 1 on the right. Since the number line is divided into 5 equal segments, mark the points that correspond to 1/5, 2/5, 3/5, and 4/5 between 0 and 1. Then, locate the point that corresponds to 2/5 and mark it on the number line. Remember to place a dot to represent the point.

How are the graphs of the functions f(x) = 16and g(x) = 3/64"related?
Answer:
The graphs of the functions are both straight lines and parallel to x-axis
Step-by-step explanation:
The graph of f(x) is the line y = 16 which is parallel to x-axis.
This is because for every value of x the function f(x) only takes the value 16
Similarly the graph of g(x) is also a straight line but is characterized by y = 3/64. This line is also parallel to the x-axis.
For every value of x the function g(x) only takes the value 3/64

z^2-5z+4=0
Answer:
[tex]z^2-5z+4=(z-4)(z-1)[/tex]
Step-by-step explanation:
To factorize a cuadratic equation, one must use the well known formula to find the roots of the equation: [tex]\frac{-b(+-)\sqrt{b^2-4ac} }{2a}[/tex], where a (a=1) is the coefficient that accompanies the cuadratic term, b is the coefficient that accompanies the linear term (b=-5) and c is the constant (c=4).Then, applied to this specific case, the previous formula results: [tex]\frac{5(+-)\sqrt{(-5)^2-4\times{1}\times{4}} }{2\times1}[/tex]. Then, the two roots of the equation come from [tex]\frac{25(+-)\sqrt{9} }{2}[/tex].Consecuently, [tex]z_1=\frac{5+\sqrt{9}}{2} =4[/tex], and [tex]z_2=\frac{5-\sqrt{9}}{2} =1[/tex].Finally, the cuadratic function can be expressed like this: [tex](z-4)(z-1)[/tex] (which comes from the fact that any polynomial can be expressed as the product of [tex](x-x_i)[/tex], where i are the roots of the polynomial). To corroborate that the procedure is correct, you can resolve this product, and you will obtain the inicial expression.What is 62 divided by 5,841

2. When Mrs. Romano was pricing cans of tomato sauce, she noticed the following prices.
1 can (28 ounces) cost $1.89
1 can (32 ounces) costs $2.95
Which is the better deal?
need to know the unit rate too please.
Answer:
28 oz can is the better deal.
Step-by-step explanation:
In order to compare the two, we need to find the unit rate for each can. In this case, the unit rate will be in dollars per oz.
For the 28 oz can,
unit rate = $1.89 ÷ 28 = $0.675 / oz
For the 32 oz can
unit rate = $2.95 ÷ 32 = $0.922 / oz
comparing the unit rates, we can see that the unit rate for the 28 oz can is lower (i.e it costs less per oz for the 28 oz can compared to the 32 oz can)
Hence the 28 oz can is the better deal.

Step-by-step explanation:
In the division problem A ÷ B = Q [tex]\frac{R}{B}[/tex], where
A is the dividendB is the divisorQ is the quotientR is the remainderIf A is divisible by B, then R = 0
Examples:
23 ÷ 5 = 4 [tex]\frac{3}{5}[/tex] , The dividend is 23, the divisor is 5, the quotient is 4, and the remainder is 354 ÷ 6 = 9, 54 is divisible by 6 , then the remainder = 0The rule of the dividend is ⇒dividend = (divisor × quotient) + reminder
Let us use this rule to find x
984 ÷ x = 4, remainder 84
∵ Dividend = 984
∵ Divisor = x
∵ Quotient is 3
∵ Remainder = 84
- Substitute these values in the rule of dividend above
∵ 984 = (x × 3) + 84
∴ 984 = 3x + 84
- Subtract 84 from both sides
∴ 900 = 3x
- Divide both sides by 3
∴ 300 = x
∴ The value of x = 300
The value of x in 984 ÷ x = 3 remainder: 84 is 300

Answer:
√(4/5)
Step-by-step explanation:
First, let's use reflection property to find tan θ.
tan(-θ) = 1/2
-tan θ = 1/2
tan θ = -1/2
Since tan θ < 0 and sec θ > 0, θ must be in the fourth quadrant.
Now let's look at the problem we need to solve:
sin(5π/2 + θ)
Use angle sum formula:
sin(5π/2) cos θ + sin θ cos(5π/2)
Sine and cosine have periods of 2π, so:
sin(π/2) cos θ + sin θ cos(π/2)
Evaluate:
(1) cos θ + sin θ (0)
cos θ
We need to write this in terms of tan θ. We can use Pythagorean identity:
1 + tan² θ = sec² θ
1 + tan² θ = (1 / cos θ)²
±√(1 + tan² θ) = 1 / cos θ
cos θ = ±1 / √(1 + tan² θ)
Plugging in:
cos θ = ±1 / √(1 + (-1/2)²)
cos θ = ±1 / √(1 + 1/4)
cos θ = ±1 / √(5/4)
cos θ = ±√(4/5)
Since θ is in the fourth quadrant, cos θ > 0. So:
cos θ = √(4/5)
Or, written in proper form:
cos θ = (2√5) / 5
What is the difference between an equation with a variable and an inequality with a variable?
Answer:
An equation is a statement that maintains the equal value of two mathematical expressions. If the statement is true for all variable values, it is called an identity. ... An equation shows the equality of two variables while an inequality shows the inequality of two variables
An equation with a variable expresses a precise equality between expressions, while an inequality with a variable represents a range of possible values expressing that one value is greater or less than another. Equations typically have a definitive set of solutions, whereas inequalities signify a continuum of solutions that satisfy the relational condition.
Explanation:The difference between an equation with a variable and an inequality with a variable lies in the relationship they describe between the variables. An equation states that two expressions are equal by means of the equal sign (=), implying a specific value or set of values for the variables involved. For example, in the equation of a line y = mx + b, where x and y are the variables on the horizontal and vertical axis respectively, and b and m represent the y-intercept and the slope, we can see a direct relationship between x and y that determines the position of a point on a Cartesian plane. Conversely, an inequality such as x > y or x < 10 indicates a range of possible values rather than a single specific value, expressing a relationship where one value is either greater than or less than another value, but not equal to it.
In the context of a graph, the independent variable typically plotted on the x-axis is assumed to be the cause or input which then determines the value of the dependent variable, depicted on the y-axis. The dependent variable changes in response to the independent variable, thereby showing their relationship. This is often represented by inequalities when a range of outcomes is possible, extending beyond the linear relationship that might be depicted with an equation.

of the cover? Use pi = 3.14 and round the answer to the nearest square foot.
Answer:
The area of the cover for the hot tub must be:
38 square feet.Step-by-step explanation:
First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:
Area of a circle = pi * radius ^ 2 (you must know that the radius is half the diameter)Since the diameter is mentioned, it can be replaced in the formula:
Area of a circle = 3.14 * (3.5 feet) ^ 2 Area of a circle = 38,465 square feet. Approximately 38 square feet.Answer:

mio bought a tablet and pays monthly for internet service for it. she graphed the relationship between the number of months she has had the tablet and the total amount she has spent on it.
what does the y-intercept represent in this context?
A) the number of months after which the total cost is 0 dollars
B) the cost of buying the tablet
C) the cost per month
D) none of the above
In the context of the question, the Y-intercept represents the cost of the tablet that Mio purchased before counting the ongoing costs per month for internet service.
Explanation:In the context of this problem, the Y-intercept in the graph represents the cost of buying the tablet. Using the algebraic equation for a line, which is y = b + mx, the 'b' term is the Y-intercept. When x (in this case, the number of months) equals zero, y is the initial cost, which serves as our Y-intercept. This is the starting point on the Y-axis, and in the context of Mio's spending, this would be her initial expenditure which is the cost of the tablet itself.

A school receives a shipment of books. There are 60 cartons, and each carton weighs 42 pounds. The school’s elevator can hold 2200 pounds. What is the greatest number of cartons that can be carried on the elevator at one time if no people ride with them? Show all of your work. Then, explain your solution.
Answer:
52
Step-by-step explanation:
2200 / 42 = 52.381
You cannot bring a section of a carton, and 53 cartons is too much
53 * 42 = 2226. This goes over the weight limit.
52 * 42 = 2184. 2184 is less than 2200, so 52 is the greatest number you can bring
By dividing the elevator's weight capacity of 2200 pounds by the weight of one 42-pound carton, we find it can carry a maximum of 52 whole cartons simultaneously without exceeding the weight limit.
Explanation:To solve this problem, we can use simple mathematical analysis. We need to calculate how many 42-pound cartons can fit into an elevator that has a maximum capacity of 2200 pounds without exceeding this limit.
We start with the equation:
Divide the maximum weight the elevator can hold by the weight of one carton. 2200 pounds ÷ 42 pounds/carton = 52.38 cartons.Since you can't have a fraction of a carton, you need to round down to the nearest whole number. The greatest number of whole cartons is 52.Therefore, the elevator can safely carry 52 cartons at once, without any people in it.
