Solve the equations to find the number and type of solutions. The equation 8 − 4x = 0 has real solution(s).
Answer:
The number of solution is, 1 and the type of solution is, Integer solution.
Step-by-step explanation:
Given the equation:
[tex]8-4x=0[/tex]
Add 4x to both sides we have;
[tex]8 = 4x[/tex]
Divide both sides by 4 we have;
[tex]2 = x[/tex]
or
x = 2
Solution for this equation is, 2
Therefore, The number of solution is, 1 and the type of solution is, Integer solution.
The equation has a single real solution, x = 2.
The equation 8 − 4x = 0 can be solved as follows:
8 − 4x = 0
4x = 8
x = 2
The equation has one real solution, x = 2.
A real solution is a solution that is a number. The number 2 is a real number, so the equation has one real solution.
Here is a more detailed explanation of the solution:
We subtract 8 from both sides of the equation.
We divide both sides of the equation by -4.
We simplify both sides of the equation.
The answer is x = 2, which is a real number. So, the equation has one real solution.

The area of square abcd is 36 square units and the area of triangle ebf is 20 square units. if line eb is perpindicular to line bf and line ae is equal to 2 find the length of line cf
Final answer:
The length of line CF is 20 units.
Explanation:
Let's analyze the given information step by step:
The area of square ABCD is 36 square units, so each side of the square measures √(36) = 6 units.The area of triangle EBF is 20 square units.Line EB is perpendicular to line BF.Line AE is equal to 2 units.Since line EB is perpendicular to line BF, triangle EBF is a right triangle. Let's assume the length of line BF is x units. Using the area of a triangle formula, we have:
Area of triangle EBF = (1/2) * base * height
20 = (1/2) * x * 2
Simplifying the equation, we get:
20 = x
Therefore, the length of line BF (or CF) is 20 units.

AB=2y+1, BC=y+1,CD=7x-3,DA=3x what is x and y
Given the segments of a quadrilateral, the steps show that for it to be closed, the expression 3y + 10x + 1 = 0 must hold. Additional information would be needed to find unique values for x and y.
Given the segments AB, BC, CD, and DA of a quadrilateral:
AB = 2y + 1BC = y + 1CD = 7x - 3DA = 3xFor a quadrilateral to be closed, the perimeter equations must be equal. Thus, we set up the equality:
AB + BC + CD + DA = 0
Substituting the given segment expressions:
(2y + 1) + (y + 1) + (7x - 3) + (3x) = 0
Simplifying this equation:
3y + 4 + 10x - 3 = 0
Combine like terms:
3y + 10x + 1 = 0
This represents a linear equation involving x and y.
Assuming the quadrilateral is closed, another equation or condition is needed to solve for x and y simultaneously. If additional geometric or numeric information is provided about the quadrilateral, it can help solve the system.

The correct option is (B)
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given are ordered pairs are: (-3,0) (-2,4)(-1,8)(0,12)(1,16)(2,20).
It can be seen that the there only unit increase in x coordinates and units increase in consecutive y- coordinates.
Now, if we set up the equation of line as:
Here, m =4 and b = 12
So the relationship is linear and represented by the equation
y=4x+12
Hence, the relative difference between y-values and x-values is the same no matter which pairs of (x, y) values you use to calculate it.

A bakery sold 115 cupcakes in one day. The head baker predicted he would sell 95 cupcakes that day. What was the percent error of the baker's prediction?
The baker's prediction had a 17.39% error.
To calculate the percent error of the baker's prediction, we use the formula:
Percent Error = (|Actual Value - Predicted Value| / Actual Value) * 100%
In this case, the Actual Value is the number of cupcakes actually sold, 115. The Predicted Value is the number the baker predicted to sell, 95.
So, the computation will be:
Percent Error = (|115 - 95| / 115) * 100%
Percent Error = (20 / 115) * 100
Percent Error = 0.1739 * 100%
Percent Error = 17.39%

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (−2, 4)? y = – x – 1y = – x + 5y = x – 1y = x + 5
Answer: The required equation of the line is [tex] y=-\dfrac{5}{2}x-1.[/tex]
Step-by-step explanation: We are given to find the equation of the line that is parallel to the following line and passes through the point (-2, 4) :
[tex]5x+2y=12~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
the slope-intercept form of the equation of a straight line is given by
[tex]y=mx+c,[/tex]
where m is the slope of the line.
From equation (i), we have
[tex]5x+2y=12\\\\\Rightarrow 2y=-5x+12\\\\\Rightarrow y=-\dfrac{5}{2}x+6.[/tex]
So, the slope of line (i) is given by
[tex]m=-\dfrac{5}{2}.[/tex]
We know that the slopes of two parallel lines are equal. So, the slope of the new line will be
[tex]m=-\dfrac{5}{2}.[/tex]
Since the line passes through the point (-2, 4), so its equation will be
[tex]y-4=m(x-(-2))\\\\\\\Rightarrow y-4=-\dfrac{5}{2}(x+2)\\\\\\\Rightarrow y-4=-\dfrac{5}{2}x-5+4\\\\\\\Rightarrow y=-\dfrac{5}{2}x-1.[/tex]
Thus, the required equation of the line is [tex] y=-\dfrac{5}{2}x-1.[/tex]

The perimeter of a square must be greater than 188 inches but less than 198 inches. find the range of possible side lengths that satisfy these conditions. (hint: the perimeter of a square is given by p=4s, where s represents the length of a side).
The range of possible side lengths for the square is from slightly more than 47 inches to slightly less than 49.5 inches. This is found by dividing the given perimeters by 4, using the formula p=4s.
Explanation:In this problem, we need to find the range of possible side lengths of a square where the perimeter is more than 188 inches but less than 198 inches. Remember that the perimeter of a square is found by multiplying the length of one side by 4 (p=4s).
First, let's find the side length for a square with a perimeter of 188 inches. We do this by dividing the perimeter by 4: 188 / 4 = 47 inches. So, any square with side lengths greater than 47 inches would have a perimeter more than 188 inches.
Next, we find the side length for a square with a perimeter of 198 inches. Similarly, we divide the perimeter by 4: 198 / 4 = 49.5 inches. So any square with side lengths less than 49.5 inches would have a perimeter less than 198 inches.
Therefore, the range of possible side lengths that satisfy these conditions is from slightly more than 47 inches to slightly less than 49.5 inches.

Which transformation shows a reflection of ΔDEF?
The answer is B or the purple one
Answer:
The image B with purple figures is correct.
Step-by-step explanation:
We are given the figure DEF and we are required to find the figure which is obtained after reflecting it.
Now, reflection of a figure means to flip the figure over a line.
In the green figure, the points D and E are interchanged which is not possible in reflection.
In the blue figure, there is no change.
In the purple figure, the triangle is flipped over the line DE and so it is the correct answer.
Hence, the purple figure is obtained after reflecting the figure DEF.

The graph of a quadratic function touches, but does not cross, the x-axis at x = 4. Which function represents this situation? y = x2 – 16 y = x2 – 4x y = x2 – 8x + 16 y = x2 + 8x + 16
The quadratic equation is y = x^2 - 8x + 16
How to determine the equation?From the question, we have:
x = 4
Since the graph only touches x = 4 and it does not cross it, then it means that the graph has a multiplicity of 2 at x = 4
The equation is then represented as:
y = (x - 4)^2
Expand
y = x^2 - 8x + 16
Hence, the quadratic equation is y = x^2 - 8x + 16

If you were given the equation f ( x ) = 3x⁵+6x, what behavior would the ends of the graph have?
a. Both ends will point up
b. Both ends will point down
c. the left end will start down at a large negative and the right end will go upwards
d. the left end will start up at a large positive and the right end will go downwards EXPLAIN ANSWER
The ends of the graph of the function f(x) = 3x^5 + 6x will display the behavior described in option c. This is due to the highest power of x in the equation being an odd number and the coefficient being positive. As such, the left end of the graph will start down at a large negative and the right end will go upwards.
Explanation:The behavior of the ends of the graph of the function f(x) = 3x^5 + 6x is determined by the highest power of x in the equation, which is 5 in this case. The coefficient of x^5 is positive, so as x approaches positive infinity, f(x) also approaches positive infinity. Conversely, as x approaches negative infinity, the value of f(x) would approach negative infinity. We can describe this behavior as the left end of the graph starting at a large negative and the right end going upwards. Thus, answer c. 'the left end will start down at a large negative and the right end will go upwards' is correct.
