Answer:
1) When we have a function y = f(x), evaluating this function in one given point (x0 for example ) is equivalent to changing the x inside the function by the value x0.
This will give us the point (x, f(x0)).
now, a graph is conformed by the set of all the points (x, f(x)).
2) The x and y-intercepts are the points where the graph intercepts the x-axis or the y-axis.
If you have a table with points (x, y), the y-intercept is the point (0, y') and the x-intercept is the point (x', 0)
Where x' and y' are known values.
If you have an equation:
y = f(x).
The x-intercept is the point (x', 0)
So you need to find the value x' such that f(x') = 0.
The y-intercept is the point (0, y')
So you need to evaluate the function in x = 0, and find the value of y.
y' = f(0).
3) The obvious answer is any science-related career, where graphs are used to transmit a lot of information with almost no words.
Another option can be an economist, where, for example, interpreting and comparing graphs can be useful to determine which option fits better the needs of a given company or what decision is better to be taken.
Juan drove 126 miles in 3 hours. If he continued at the same rate, how long would it
take to travel 336 miles?
Answer:
if he drove 9 hours it would 378 miles
The time Juan would take to travel 336 miles if he drove 126 miles in 3 hours is 8 hours.
What is multiplication?
One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.
Given:
Juan drove 126 miles in 3 hours,
Calculate the number of hours he takes to drive 1 mile,
1 mile = 3 / 126
336 miles = 3 / 126 × 336
Therefore, The time Juan would take to travel 336 miles if he drove 126 miles in 3 hours is 8 hours.

Step-by-step explanation:
The club supplies 40 new balls for each player which cost $1 each. Each player pays $300 for the lessons. The club must pay each instructor $1,000 for conducting the lessons, and there must be at least 1 instructor for every 6 players. Which amount of players and instructors meets these requirements and still gives the club a net profit?
Answer:
4 players and 1 instructor
Step-by-step explanation:
If all 4 players pay $300 each, that equals $1,200. The instructor will get $1,000 of it. That means there is $200 left. They need 40 balls per player. Each ball is $1, so that's $40 per player. 40 x 4= 160 200-160 = 40 The club will have $40 left.
A square field has 3844 m² of land what is the width of the field?
a = one side of a square
The area of a square = a^2
In our problem,
Area = 3844 m^2
a = ?
Let's plug our values into the area equation.
3844 m^2 = a^2
Take the square root of both sides
62 m = a
The width of the field is 62 meters
Write the equation in standard form for the hyperbola with vertices (-8,0) and (8,0), and foci (-10,0) and (10,0).
Answer:x56-8
Step-by-step explanation:
1. Find the equation of a line that passes through the point (4,1) and is perpendicular to the
line that contains the points (3,-7) and (-1,9).
Answer:
x - 4y = 0 . . . in standard form
y = (1/4)x . . . in slope-intercept form
Step-by-step explanation:
The slope of the given line is ...
m = (y2 -y1)/(x2 -x1) = (9 -(-7))/(-1 -3) = 16/-4 = -4
The slope of the perpendicular line is the negative reciprocal of this:
desired slope = -1/m = -1/-4 = 1/4
This can be used in the point-slope form of the equation of a line:
y -h = m(x -k) . . . . . line with slope m through point (h, k)
Your perpendicular line has a slope of 1/4 and goes through point (4, 1), so its equation can be written as ...
y -1 = (1/4)(x -4)
y = (1/4)x -1 +1
y = (1/4)x
In standard form, this is ...
4y = x
x -4y = 0
Solve for x. 3/4 = 16/x

What must be true of the units in two rates if one rate can be converted to the units of the other rate? In other words, the units of the first rate are both/all distinct from that of the converted rate, but it still represents the same measurement.
Answer:
We have two rates, A and B.
If we want that the units of A can be converted into the units of B, then we must have that the units of A represent the same measure that the units of B.
What does this mean?
For example, if A is written in distance over time, then B must also must have units of distance over time.
An example would be:
units for distance = meter, kilometer, feet, etc.
units for time = hour, minute, second, etc-
Then we could have:
[A] = [km/h]
[B] = [m/min]
Then the units of A could be converted into the ones of B, because both of them have the same physical meaning.
Concluding, you only can convert units that represent the same physical quantity, for example, if you have one quantity in meters, for example:
10m
You only can convert this to other units of distance, remember to do the correct conversion, if we would want to write this in cm, you should remember that:
1m = 100cm
Then, 10 times one meter is 10 times 100 cm
10m = 10*(1m) = 10*(100cm) = 1000cm

The polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2, so option A is correct.
What is polynomial?A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.
Given:
3x²y² − 5xy² − 3x²y² + 2 x 2
Simplify the above expression,
3x²y² − 5xy² − 3x²y² + 2 x 2 = -55xy² + 4
As you can see from the expression, it has the two-term and highest degree of 2
Therefore, the polynomial 3x²y² − 5xy² − 3x²y² + 2 x 2 after fully simplified has 2 terms and a degree of 2.

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are going on the trip, so they need at least 505050 total rooms. Joe had already reserved and paid for 161616 rooms, so he needs to reserve additional rooms. He can only reserve rooms in blocks, and each block contains 888 rooms and costs \$900$900dollar sign, 900. Let BBB represent the number of additional blocks that Joe reserves.
Answer:
$4500
Step-by-step explanation:
Strategy
Joe needs the rooms he's already reserved plus the additional rooms to be at least 505050. We can represent this with an inequality whose structure looks something like this:
\left( \text{rooms already reserved} \right) + \left( \text{additional rooms} \right) [\leq \text{or} \geq] \,50(rooms already reserved)+(additional rooms)[≤or≥]50left parenthesis, start text, r, o, o, m, s, space, a, l, r, e, a, d, y, space, r, e, s, e, r, v, e, d, end text, right parenthesis, plus, left parenthesis, start text, a, d, d, i, t, i, o, n, a, l, space, r, o, o, m, s, end text, right parenthesis, open bracket, is less than or equal to, start text, o, r, end text, is greater than or equal to, close bracket, 50

Mrs. Sanchez asked her students to
classify the following value as rational or
irrational:
0.62581
Ryan thinks the value is irrational because
the decimal does not have a pattern.
Do you agree with Ryan? Why or why not?
Answer:
The answer is that it is a rational number because it is a terminating decimal
Step-by-step explanation:
0.62581 is a rational number.
What are rational numbers and irrational numbers?
Rational numbers are numbers that can be written as the ratio of two integers. For example: 1/2, 3/4, are rational numbers.
Irrational numbers, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.
Now the given number is,
0.62581
Now here we see that the numbers after decimal are terminating and non-repeating.
Also the digit after decimal stops.
Hence the number 0.62581 is rational.
