The solutions to both sets of simultaneous equations by graphical method are; No solution
How to graph simultaneous equations?There are three main ways to solve simultaneous linear equations and they are;
1) Elimination method
2) Substitution method
3) Graphical Method
In this question, we are using the graphical method where the solution will be the coordinate of the point of intersection.
1) The 2 simultaneous linear equations are;
y = ¹/₂x + 1
-2x + 4y = 4
The graph of these 2 equations is as attached.
From the first graph attached, we see that both lines overlap each other and as such don't have any point of intersection which tells us there is no solution to the simultaneous linear equations
2) The 2 simultaneous linear equations are;
y = -x - 3
y + x = 2
The graph of these 2 equations is as attached.
From the second graph attached, we see that both lines don't intersect each other and as such don't have any point of intersection which tells us there is no solution to the simultaneous linear equations

Two triangles are congruent if and only if they have the same shape and size.
What is triangle ?
A triangle in which it is having three sides , three angles and the sum of three angles is always 180 degrees.
So, there are several ways to find out if two triangles are congruent, so we will study the triangles above to find the answers:
Case a. (AAS - Angle, Angle, Side)
AAS stands for "angle, angle, side" and means that we have two triangles where we know two angles and the non-included side are equal. So, for the figure above it is true that:
∠B = ∠E
∠A = ∠D
Case b. We don't have any information about this case that allows us to get a conclusion about congruence. Recall that for congruent triangles you need to compare three elements two by two.
Case c. (SSS - Side, Side, Side)
SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. So, for the figure:
Case d. We only have two equal elements, but it is necessary to have three elements for comparing them doing the comparison two by two. There is not enough information for getting a conclusion.

Is X² and 2x like terms?
Answer: No, x^2 and 2x are not like terms. Like terms are terms that have the same variable raised to the same exponent. In this case, x^2 and 2x have the same variable, but they are raised to different exponents, so they are not like terms.
Terms can be added or subtracted together, but terms that are not like terms cannot be combined.
For example:
5x^2 and 2x^2 are like terms, so they can be added together (5x^2 + 2x^2 = 7x^2)
5x and 2x are like terms, so they can be added together (5x + 2x = 7x)

The area of a triangle i found uing the following formula:
If b = 3 in. And h = 8 in. , what i the area of the triangle?
So, the area of the triangle is 12 square inches.
In a two-dimensional plane, the area of a triangle is the region enclosed by it. A triangle, as we all know, is a closed form with three sides and three vertices. Thus, the area of a triangle is the total space filled by the triangle's three sides. The typical formula for calculating the area of a triangle is half of the product of its base and height.
The area of a triangle can be found using the formula: (1/2) * b * h
Given that b = 3 in. and h = 8 in., the area of the triangle would be:
(1/2) * 3 * 8 = (1/2) * 24 = 12 square inches.

The pair in the solution of the equation -2x + 3y = 6 is (0,2).
Solution of equationThe set of all values that, when substituted for unknowns, make an equation true is known as the solution.
Solution of linear equation in two variablesA specific location on the graph is the solution of a linear equation in two variables, where ax+by = c, meaning that when the x-coordinate is multiplied by a and the y-coordinate is multiplied by b, the sum of these two values equals c. There are essentially an endless number of solutions to a linear equation with two variables.
Now in the question,
To find the pair of solutions of the equation -2x + 3y = 6, we satisfy all the pairs one by one in the given equation
1. Putting the value of (x, y) as (-3,4) in the equation we get-
-2*-3 +3*4 = 6 ⇒ 18 = 6
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
2. Putting the value of (x, y) as (3,-4) in the equation we get-
-2*3 + 3*-4 = 6 ⇒ -18 = 6
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.
3. Putting the value of (x, y) as (0,2) in the equation we get-
-2*0 + 3*2 = 6 ⇒ 6 = 6
Therefore LHS = RHS
Hence it is the solution to the equation.
4. Putting the value of (x, y) as (3,0) in the equation we get-
-2*3 + 3*0 = 6 ⇒ -6 =6
Therefore LHS ≠ RHS
Hence it is not the solution to the equation.

What is the formula of the slope when given two coordinates of two points?
The formula for the slope (also known as the "rise over run" or "gradient") of a line when given the coordinates of two points is:
m = (y2 - y1) / (x2 - x1)
Where (x1, y1) and (x2, y2) are the coordinates of the two points, and m is the slope of the line.
Note that the coordinates must be in a Cartesian coordinate system, and the points must be distinct, otherwise, the denominator (x2 - x1) will be zero and the division by zero is not defined.
For example, if you have two points (2, 4) and (6, 8), you can use the slope formula to find the slope of the line:
m = (8-4) / (6-2) = 4/4 = 1
The slope of the line is 1

Suppose that triangle DEF is isosceles with base FD. Suppose also that angle E=(5x+59)° and angle F=(2x+38)°. Find the degree measure of each angle in the triangle
The value of angle D, angle E, angle F are 48° , 84° and 48° respectively
What is an isosceles triangle?An isosceles triangle is a triangle with two equal sides. In the figure above, the two equal sides have length and the remaining side has length. . This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.
Since E is not equal to F then we can possibly say F = D since the triangle is an isosceles triangle.
Therefore :
180 = 5x+59 + 2x+38 + 2x + 38
180 = 9x + 135
9x = 180-135
9x = 45
x = 5
therefore angle E = 5×5 + 59 = 25+59 = 84°
angle D = F = 2×5 + 38 = 10 + 38 = 48°
therefore D = 48°, E = 84°, F = 48°

227 18-inch cubes can fit inside the rectangular prism.
How is this determined?You may calculate how many 18-inch cubes can fit within a rectangular prism by dividing the rectangular prism's overall volume by the volume of a single 18-inch cube.
A rectangular prism's volume can be calculated using the formula length x width x height. In this instance, the dimensions are 312 inches long, 212 inches wide, and 3 inches high. As a result, the rectangular prism has a volume of 1,326,720 cubic inches (312 x 212 x 3).
A single 18-inch cube has a volume of 18 x 18 x 18 = 5832 cubic inches.
We divide the volume of the rectangular prism by the volume of a single 18-inch cube to get the number of 18-inch cubes that can fit inside: 1,326,720 / 5832 = 227.
Therefore, the rectangular prism can accommodate 227 18-inch cubes.

How do you find the base value?
The base value of a numeral system can be founded by counting the number of unique digits or symbols used in the system.
FIND THE BASE VALUEThe base value of a numeral system can be determined by counting the number of unique digits or symbols used in the system. For example, in the base 10 numeral system, which is commonly used in everyday life, the base value is 10 because it uses the digits 0 through 9. In the base 2 numeral system, which is also known as binary, the base value is 2 because it only uses the digits 0 and 1.
Another way to find the base value is to look at the exponent of the highest power of the base in the numeral system. For example, in the number 42 in base 10, the highest power of 10 is 10¹, which is 10. Therefore, the base value is 10. Similarly, in the number 1010 in binary, the highest power of 2 is 2³, which is 8. Therefore, the base value is 2.

Write and solve an inequality which can be used to determine oo, the number of outfits Rashon can purchase while staying within his budget.
The inequality is x ≤ 5.09, where x is the number of outfits. Rashon can buy at most 5 outfits while staying within his budget.
To determine the number of biking outfits Rashon can buy while staying within his budget, you can set up an inequality using the information provided.
First, calculate the total cost of the reflectors and gloves:
3 reflectors × $10.78 + $32.64 = $38.34 + $32.64 = $71
Then, subtract the cost of the bicycle, reflectors, and gloves from Rashon's budget: $780 - $481.28 - $71 = $227.72
Now, you can use this remaining amount to determine the number of biking outfits Rashon can buy.
Let x be the number of outfits he can buy
You can set up an inequality as follows:
44.95x ≤ $227.72
Dividing both sides by 44.95:
x ≤ 5.09
However, since the number of outfits is an integer, he can only buy 5 outfits at most.
