Answer:
x=-2,y=10
Step-by-step explanation:
y=8-x.............equation 1
4-y=-5..........equation 2
Now,
putting the value of y in equation 2,
4-(8-x)=-5
4-8+x=-5
-3+x=-5
x=-5+3
x=-2
Then,
putting the value of x in equation 1
y=8+2
y=10
How do you find the reflecting on a coordinate plane( x-axis or y-axis )?
A transformative process turns a figure into a reflection.
How do you determine the reflecting on an x-axis or y-axis coordinate plane?If you want to reflect a point across the x-axis, multiply its y-coordinate by -1. If you want to reflect a point across the y-axis, multiply its x-coordinate by -1.A transformative process turns a figure into a reflection.When a point is reflected across the x-axis, the x-coordinate stays constant, but the y-coordinate is thought to be the additive inverse. The x-axis shows a reflection of the point (x, y) as (x, -y).The y-coordinate remains constant when a point is mirrored across the y-axis, while the x-coordinate is thought to be the additive inverse. The point (x, y) is reflected on the y-axis as (-x, y).(x, y)(x, y) is the formula for a reflection over the x-axis.
(x,y)(x,y) is the formula for a reflection across the y-axis.
The formula is (x,y)(y,x) for a reflection in the line y=x.
(x, y)(y, x) is the formula for a reflection in the origin.

And, The expression is equivalent to 2 divide by 3
Now, According to the question:
All those fractions obtained by multiplying both the numerator and denominator of 2/3 by the same integer are equivalent to 2/3.
2/3 × 2/2 = 4/6
2/3 × 3/3 = 6/9
2/3 × 4/4 = 8/12
2/3 × 5/5 = 10/15 and so on...
4/6, 6/9, 8/12, 10/15 ... are equivalent to 2/3.

What is the value of angle?Any triangle's three angles sum up to 180 degrees when added together. Therefore, the sum of angles A, B, and C is 180 degrees. Any triangle in the field of geometry has this property. This concept can be used to determine the measure of an angle or angles in which the degree measure is absent or not provided.
A, B, and C is 180 degrees
in a triangle <u- 40 degree <u+50 degree so <u is

so
<u =
(u - 40 ) + (u+50 ) + u = 180

What is the meaning of x³ in math?
To answer, let's use the exponent rules, here x³ denotes "x multiplied by itself three times,"
What is exponent rule?Exponents, often known as powers, specify how many times the base number must be multiplied.
Exponent rules are principles that are used to simplify expressions using exponents. These principles are also useful in simplifying formulas with exponents that are decimals, fractions, irrational numbers, or negative integers.
Negative exponents Rule: [tex]a^{-m} = 1/a^m[/tex]Product Rule: [tex]a^m * a^n = a^{(m+n)}[/tex]Quotient Rule: [tex]a^m / a^n = a^{(m-n)}[/tex]Power of a Power Rule: [tex](a^m)^n = a^{mn}[/tex]An exponent is just a shortened way to denote repeated multiplication. x³ (or "x to the third power") in algebraic terms denotes "x multiplied by itself three times," or x x x.
Power is a mathematical phrase that denotes the repeated multiplication of a value or number.

How do you draw a linear graph?
An equation that depicts a straight line on a graph is said to be linear line.
What is linear line?Linear refers to a straight line. Straight-line graphs called linear graphs are used to show the relationship between two values. The single straight lines on this graph assist to represent a result. The phrase "linear" refers to a straight line and excludes the usage of curves, dots, bars, etc.
A linear line can include more than one variable. Linear lines with two variables, for example, are those that have two variables in them. 2x - 3 = 0 and 2y = 8 are few examples of linear lines.
Steps to draw a linear graph are described below:
A linear relation's graph can be discovered by graphing at least two points. The intercepts lead to the discovery of two locations that are very helpful for illustrating the graph of a line. A graph's x-value at which it crosses the x-axis is known as the x-intercept. A graph's y-value at where it crosses the y-axis is known as a y-intercept. Since the x-axis has a value of y = 0, an x-intercept may be discovered by setting y in the equation to 0 and figuring out x. Setting x = 0 in the equation and calculating y leads to the discovery of a -y intercept.To know more about linear lines refer to:

What is a line?
A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.
The points on the line are (-4, 5), (0,2), (4, -1).
The slope of a line that passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).

The scatter plot shows the number of pumpkins that have been picked on the farm during the month of October:
Part A: Using computer software, a correlation coefficient of r = 0.51 was calculated. Based on the scatter plot, is that an accurate value for this data? Why or why not?
Part B: Instead of comparing the number of pumpkins picked and the day in October, write a scenario that would be a causal relationship for pumpkins picked on the farm.
The number of pumpkins that were harvested on the farm during in the month of October is shown below, in accordance with the correlation concept.
It is, in Part A.
Part B: the quantity of harvested pumpkins and the quantity of fertiliser used.
what is correlation?
Correlation is a statistical measure that evaluates the strength of a relationship between two variables. It can range from -1 to +1, where -1 indicates a perfect negative linear correlation, 0 indicates no linear correlation, and +1 indicates a perfect positive linear correlation. Correlation is used to measure the strength of the relationship between variables, and whether changes in one variable are associated with changes in the other. Correlation analysis can also help to identify patterns and trends in data, and can be used to make predictions about future outcomes.
Part A:
The stronger the correlation between two variables, as well as vice versa, the closer this same correlation coefficient is to 1. Additionally, the correlation coefficient is closer to 1 the closer this same data points are spaced apart on a scatter plot.
The scatter plot depicted shows a correlation between the quantity of pumpkins and the number of days. The data points are, however, somewhat further apart from one another. The two variables have a moderate relationship, as evidenced by this. Consequently, the calculated correlation coefficient, r, of 0.51 can be regarded as accurate because r of 0.51 denotes a moderate relationship between the two variables.
Part B:
Instead of the day in October, the amount of fertiliser used could have an impact on the number of pumpkins harvested. As a result, we can evaluate the quantity of pumpkin harvested and fertiliser used.
Therefore,
Part A: YES, it is.
Part B: the quantity of harvested pumpkins and the quantity of fertiliser used.
