What are Rational numbers and Irrational Numbers?Any number in the form of p/q where q not equal to zero is called as rational Number.
An Irrational Number is a real number that cannot be written as a simple fraction: 1.5 is rational, but π is irrational. The root values will also be irrational.
The number -3 is a rational number. We can write -3 in the form of p/q, i.e -3/1 where p is -3 and q is 1.
All rational numbers are obtained by dividing one integer by another.
Since it is possible to obtain -3 by dividing the integer
i.e -3 by 1, as in -3/1,

a B is (7, 10)
b Bis (9, 12)
c B is (10, 10)
d B is (13, 10)
The other endpoint is (7,10).
Assuming that your midpoint M = (x, y) and endpoint A = (x1, y1) are both present: Coordinates of the double midpoints are 2x, 2y. To find the x-coordinate of the missing endpoint, subtract the known endpoint's x-coordinate from the first value: x₂ = 2x - x₁.
The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint.
An alternate solution would be to substitute (-1, 2) for (x1,y1) and (3,6) for (x2,y2) into the midpoint formula:
(x - 1)/2 = 3
x -1 = 6
x =7
(y + 2)/2 = 6
y + 2 = 12
y =10
Solving each equation for (x2,y2) yields the solution (7,10).

do you think you can help me with this problem this is what the question is about a glass bottle filled with oil that weighs 590 grams. After Sophia uses 200 milliliters of oil, the bottle of oil weighs 400grams. so do u think u can help me?
The function formula of the mass of the bottle to the function of the volume of the oil is M = 590 - 0.95V
How to write function formula?The glass bottle filled with oil weighs 590 grams.
After Sophia uses 200 millilitres of oil, the bottle of oil weighs 400grams.
Therefore, the weight M of the bottle of oil in grams is a function of V, the volume, in millimetres of oil Sophia has used.
Therefore, the formula of the function can be represented as follows
density = mass / volume
200 mm reduces the weight of the bottle by 590 - 400 = 190 grams.
V mm will reduce it to ?
cross multiply
190 × V / 200 = 19 / 20 V = 0.95V
where
V = volume of the oil reduced from the bottle
Therefore, the function formula will be as follows:

A trough at the end of a gutter spout is meant to direct water away from the house. The
homeowner makes the trough from a rectangular piece of of aluminum that is 20 in. long and 12
in. wide. He makes a fold along the long sides a distance of x inches from the edge. If he wants the
trough to hold 360 in³ of water, how far from the edge should he make the fold?
Answer:20 in * (12 in - 2X in) * (X in) = 360 in3
This can be simplified by dividing both sides by 20 in:
20 in * (12 in - 2X in) * (X in) = (360 in3/ 20 in)
After dividing both sides by 20 in:
(12 in - 2X in) * X in = 18 in2
Distribute X in. across (12 in -2X in):
12X in2 - 2X2 in2 = 18 in2
1.Subtract 18 in2 from both sides:
12X in2 - 2X2 in2 - 18 in2 = 0
2. Rearrange the equation:
-2X2 in2 + 12X in2 - 18 in2 = 0
This for matches the form for a quadratic equation (Ax2 + Bx +C = 0)
You can then plug these values into the quadratic formula to solve for X

Answer:
39/15
Step-by-step explanation:
-4/5+-1/3+1 2/5+7/3
Convert all to fractions having the least common denominator. The mixed denominators of 3 and 5 could be converted to denominators of 15, thereby allowing them to be numerically combined.
-4/5+-1/3+1 2/5+7/3
(-4/5)(3/3) = -12/15
(-1/3)(5/5) = -5/15
(+1 2/5) = (5/5 + 2/5) = (7/5)(3/3) = 21/15
(7/3)(5/5) = 35/15
Since we have a common denominator (15) we can now sum the individual fractions by adding their numerators:
-12 -5 + 21 + 35 = 39
Now add back the denominator
The result is 39/15

What does it mean when a point is translated horizontally to the right by 6 units? That means its x coordinate is increased by 6 units, the y-coordinate is unchanged
(If it was translated 6 units to the left, it's x coordinate would decrease by 6 units)
So if we had a point say (1, 1) then its new x-coordinate will be (1+6, 1) or (7,1) The y-coordinate stays unchanged if the translation is horizontal
When a point is translated vertically by 6 units, its x-coordinate is unchanged but the new y coordinate is increased by 6 units (-6 units if the translation is vertically down)
So with a point (1, 1), an up translation will result in a new point (1, 7)
If both translations are applied both x and y coordinates will change to
(7, 7)
To figure out the new coordinates denoted by P'Q'R'S'T' of each of the points PQRST of the given figure:
Add 6 to the x-coordinate of each point and at the same time add 6 to the y-coordinate of that point
If you look at the graph, the original points and translated points for 6 units to right and 6 units up are
P(-3, -5) which translates to P'(-3 + 6, -5 + 6) or P'(3, 1)
The other new points are calculated the same way by adding 6 to both x and y coordinates
Q(-1, -5) ==> Q'(5, 1)
R(-1, -2) ==> R'(5, 4)
S(-3, -2) ==> S'(3, 4)
T(-3, -3) ==> T'(3, 3)
U(-5, -3) ==> U'(1, 3)
V( -5, -4) ==> V'(1, 2)
W(-3, -4) ==> W'(3, 2)
The attached graph shows the translated figure with the translated points. Essentially the original figure has been shifted 6 units to the right and 6 units up

The total number of students surveyed by Omar in his school is 1000.
Here, we are given that Omar conducted a survey of some students in his school about their favorite color.
650 of those surveyed said their favorite color was blue.
Further, 65 percent of the students surveyed said their favorite color was blue.
Let the total number of students surveyed be x

The price of Stock A at 9 A.M. was $12.17. Since then, the price has been increasing at the rate of $0.06 each hour. At noon the price of Stock B was $12.67. It begins to decrease at the rate of $0.08 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
If at noon the price of Stock B was $12.67. It begins to decrease at the rate of $0.08 each hour. If the two rates continue, the number of hours that the prices of the two stocks be the same is 3.57 hours.
Determining the stock number of hoursLet the hours when they equalize be h
Hence,
12.17 + .06h =12.67 - .08h
Combine like terms
.06h + .08h=12.67 - 12.17

250 word minimum essay on the steps of solving for both the x and y intercept.
Answer:
Step-by-step explanation:
In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y and an x-intercept is a point where the graph of a function or relation intersects with the x-axis of the coordinate system. To find the x-intercept we set y = 0 and solve the equation for x. This is because when y=0 the line crosses the x-axis. When an equation is not in y = mx + b form, we can solve for the intercepts by plugging in 0 as needed and solving for the remaining variable. For example In algebra, 2-dimensional coordinate graphs have a horizontal axis, or x-axis, and a vertical axis, or y-axis. The places where lines representing a range of values cross these axes are called intercepts. The y-intercept is the place where the line crosses the y-axis and the x-intercept where the line crosses the x-axis. For simple problems, it is easy to find the x-intercept by looking at a graph. You can find the exact point of the intercept by solving algebraically using the equation of the line.
