After 2 hours, Zoe and Wanda will complete the same total number of shirts.
Each tailor will finish 18 shirts.
What is linear equation?
An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Given that,
Zoe can embroider 2 shirts per hour, and Wanda can get through 6 shirts per hour. Zoe has already completed 14 shirts, and Wanda has completed 6 shirts.
Assume that after x hours they have finished the same total number of shirts.
The number of shirts that Zoe finished is
Z(x) = 14 + 2x ....(i)
The number of shirts that Wanda finished is
W(x) = 6 + 6x ...(ii)
When they make same number of shirts, then Z(x) = W(x)
14 + 2x = 6 + 6x
6 + 6x = 14 + 2x
Subtract 2x from both sides:
6x - 2x = 14 - 6
4x = 8
Divide both sides by 4
x = 8/4
x = 2.
Putting x = 2 in Z(x) = 14 + 2x:
Z(2) = 14 + (2×2)
Z(2) = 18

reflection over the y-axistranslation left 4, down 3Step-by-step explanation:
You want two transformations that will map segment AB to segment A"B", where the points are A(1, 1), B(5, 3), A"(-5, -2), B"(-9, 0).
ReflectionWe notice that the difference B-A is (5 -1, 3 -1) = (4, 2), and the difference B"-A" is (-9 -(-5), 0 -(-2)) = (-4, 2). These values have the same magnitudes, so we know no dilation is involved. The sign of the x direction of the segment has been reversed, which means the segment has been reflected horizontally. (B" is left of A", where B is right of A.)
Reflection over any vertical line will do, but the simplest is reflection over the y-axis.
The first transformation can be reflection over the y-axis.
TranslationThe reflected line segment will be ...
(x, y) ⇒ (-x, y)
A(1, 1) ⇒ A'(-1, 1)
B(5, 3) ⇒ B'(-5, 3)
The value that must be added to A' to move it to A" is ...
A" -A' = (-5, -2) -(-1, 1) = (-5 -(-1), -2-1) = (-4, -3) . . . . . . left 4, down 3
Similarly, the value that must be added to B' to move it to B" is ...
B" -B' = (-9, 0) -(-5, 3) = (-9 -(-5), 0 -3) = (-4, -3) . . . . . . left 4, down 3
That is, the entire segment A'B' can be moved to A"B" by a translation left 4 and down 3.
The second transformation can be translation left 4 and down 3.
__
Additional comment
The translation left could be accomplished by reflection over the line x = -2 instead of the y-axis.
The movement of the line segment could be accomplished in one transformation by rotation 126.87° clockwise about the point (-1.25, -2). The exact angle is arctan(-4/3) in the second quadrant.
A parabola has an axis of symmetry at x = 5/12. The distance between its roots is 13/6. What is the equation of the parabola?
Answer:
The axis of symmetry of a parabola is the line that divides the parabola into two mirror images. This line always passes through the vertex of the parabola. For a parabola with an axis of symmetry at x = 5/12, the vertex of the parabola is at the point (5/12, 0).
The distance between the roots of a parabola is the distance between the x-coordinates of the two points where the parabola crosses the x-axis. In this case, the distance between the roots is 13/6.
To find the equation of the parabola, we can use the vertex form of the equation, which is given by y = a(x - h)^2 + k, where (h, k) is the coordinates of the vertex and a is a constant. In this case, the coordinates of the vertex are (5/12, 0) and the constant a can be determined using the distance between the roots.
To find a, we can use the fact that the distance between the roots of a parabola is equal to the square root of the product of the coefficients of the quadratic terms in the equation. In the vertex form, the coefficient of the x^2 term is a, so we can set up the following equation to find a:
(13/6)^2 = a * (5/12)^2
Solving for a, we find that a = -1/3.
Therefore, the equation of the parabola is y = -1/3(x - 5/12)^2.

Notice that the temperatures are ordered from least to greatest.
Give the five-number summary and the interquartile range for the data set.
Five-number summary
Minimum:
Lower quartile:
Median:
Upper quartile:
Maximum:
Interquartile range:
Answer:
To find the five-number summary for a set of data, we need to find the minimum, first quartile, median, third quartile, and maximum of the data. To find the interquartile range, we subtract the first quartile from the third quartile.
The minimum temperature in the list is 50 degrees Fahrenheit. The maximum temperature is 80 degrees Fahrenheit. To find the median, we need to first find the middle value in the list. Since there are 13 temperatures in the list, the middle value is the seventh temperature, which is 64 degrees Fahrenheit.
To find the first and third quartiles, we need to divide the list into two halves at the median. The first half of the list contains the first six temperatures, and the second half contains the last six temperatures. The median of the first half of the list is the average of the third and fourth temperatures, which is 55 degrees Fahrenheit. The median of the second half of the list is the average of the sixth and seventh temperatures, which is 61.5 degrees Fahrenheit.
Therefore, the five-number summary for this data set is:
Minimum: 50
Lower quartile: 55
Median: 64
Upper quartile: 61.5
Maximum: 80
The interquartile range is the difference between the upper and lower quartiles, which is 61.5 - 55 = 6.5.

Consider the two expressions 6x^3 + 9x^2 + 4x + 7 and 3x^2 + 2 + 6x^3 + 6x^2 + 4x + 5.
a) Show that the two expressions represent equal numbers when x=10.
b) Explain why these two expressions do not represent equal numbers when x = -3/2.
c) Show that these two expressions represent equal numbers for all x other than x = -3/2.
When x = 10 the equations are equal and when x gets any value the two equations are equal.
What is equation ?
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."
The equals sign is a part of mathematical expressions known as equations. Often, algebra is used in equations. When a calculation requires an exact number but you don't know it, algebra is utilized.
When x = 10 the equation becomes
6x³ + 9x² + 4x + 7
6(10)³ + 9(10)² + 4(10) + 7
= 6000 + 900 + 40 + 7
= 6947
6x³ + 3x² + 6x² + 4x + 5 + 2
= 6x³ + 9x² + 4x + 7
= 6(10)³ + 9(10)² + 4(10) + 7
= 6000 + 900 + 40 + 7
= 6947
Both the equations are equal when x = 10
When x = -3/2 the equation becomes
6x³ + 9x² + 4x + 7
6(-3/2)³ + 9(-3/2)² + 4(-3/2) + 7
= -20.25 + 20.25 + 6 + 7
= 13
6x³ + 3x² + 6x² + 4x + 5 + 2
= 6x³ + 9x² + 4x + 7
= 6(-3/2)³ + 9(-3/2)² + 4(-3/2) + 7
= -20.25 + 20.25 + 6 + 7
= 13

What is the difference between rate of change and slope coefficient?
The terms rate of change, gradient, slope coefficient, and rise over run are all equivalent to the slope in a proportional relationship. The slope of a line describes the rate at which a variable changes in relation to another variable. Rate of change is the same concept, but it is more general and can be applied to any relationship, not just linear. Gradient is another term for the slope of a line, which is the change in one variable compared to the change in another variable. Slope coefficient is a mathematical term for the slope of a line, which is the ratio of the vertical change to the horizontal change. Rise over run is another term for the slope of a line, which describes the rate of change by measuring the vertical change (rise) over the horizontal change (run). All of these terms describe the same concept, which is the rate of change in a proportional relationship.

use implicit differeniation to find dy/dx x^2+xy+y^2+1=0
The differentiation of the given function x² + xy + y² + 1 = 0 will be 2x + y + dy/dx(x + 2y) = 0.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
As per the given,
x² + xy + y² + 1 = 0
Take the first derivative on both sides with respect to x as,
d/dx(x² + xy + y² + 1) = d/dx(0)
2x + xdy/dx + ydx/dx + 2ydy/dx + 0 = 0
2x + x(dy/dx) + y + 2y (dy/dx) = 0
2x + y + dy/dx(x + 2y) = 0

What is an angle?
In Euclidean geometry, an angle is the shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
The steps to draw a bisector of an angle:
1) Cross both rays with an arc. Place the compass point at the vertex of the angle after opening it to any width. Swing the compass so the pencil creates an arc that spans the angle's two rays.
2) Make a vertical arc inside. Place the compass such that the point is at the spot where the first ray and the first arc connect. Swing the compass to create an arc that fits inside the angle.
3) To intersect the first interior arc, draw a second interior arc. Move the point to the spot where the first arc crosses the second ray without altering the compass's breadth. Draw an internal arc by swinging the compass and intersecting it with the initial interior arc you drew.
4) From the vertex to the spot where the arcs meet, draw a line. To make sure the line is exact, use a straightedge. This line cuts the angle in half.

Now required slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (-16 - 2)/(-10 - 0)
