calculate the slope of the line given the points (-2, 6) and (0, 4)
The slope of the line given the points (-2, 6) and (0, 4) is -1. The correct answer would be option (A).
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
We have to determine the slope of the line given the points (-2, 6) and (0, 4)
Plugging in the given points, we get:
m = (4 - 6) / (0 - (-2)) = -2 / 2 = -1
So, the slope of the line is -1.
Hence, the correct answer would be an option (A).

A line segment or ray that is perpendicular to the segment at its midpoint is called perpendicular bisector.
What are perpendicular lines?A straight line that forms a 90° angle with another line is said to be perpendicular. A small square is placed between two perpendicular lines, as seen in the illustration, to indicate a right angle, also known as a 90° angle. The two lines in this instance are considered to be perpendicular to one another because they intersect at a straight angle.
A line that divides a line segment into two equal halves and forms a 90° angle at the place of intersection is called a perpendicular bisector. In other words, a perpendicular bisector splits a line segment at its halfway, creating a 90° angle.
Therefore, a line segment or ray that is perpendicular to the segment at its midpoint is called perpendicular bisector.

Square root of 16
Cube root of 4
Square root of 4
Cube root of 16
The question involves understanding square roots and cube roots in mathematics. The square root of 16 is 4 and of 4 is 2. The cube root of 4 is about 1.587 and of 16 is approximately 2.52.
Explanation:The question is related to the concept of roots, specifically square roots and cube roots. A square root of a number is a value that, when multiplied by itself, gives the original number. The square root of 16 is 4 because 4*4 equals 16. Similarly, the square root of 4 is 2 because 2*2 equals 4.
On the other hand, the cube root of a number is a value that, when multiplied by itself twice, gives the original number. The cube root of 4 is approximately 1.587 because 1.587*1.587*1.587 is roughly equal to 4. The cube root of 16 is approximately 2.52 because 2.52*2.52*2.52 is roughly equal to 16.

How to find the y-intercept from two points?
To find the y-intercept from two points, first calculate the slope using the formula m = (Y₂ - Y₁) / (X₂ - X₁). Then, substitute the slope and one coordinate into the equation y = mx + b and solve for b, which is the y-intercept. The y-intercept reveals the value of y when x = 0.
Explanation:The subject at hand pertains to the field of Mathematics, specifically, how to determine the y-intercept from two points on a line. The objective is to find the point at which the line intercepts the y-axis, denoted generally in equations as b in the form of y = mx + b, where m signifies the slope.
Here's a step-by-step process to find the y-intercept:
First, calculate the slope (m) from your two points using the formula: m = (Y₂ - Y₁) / (X₂ - X₁). Y₂ and Y₁ represent the y-values from your two points, and X₂ and X₁ represent their respective x-values.Substitute the slope (m) and one of your points into the equation y = mx + b. Solve for b which is your y-intercept.The y-intercept represents the value of y when x = 0. In context, it shows where the line crosses the y-axis.

Using the Quadratic Formula, which of the following is the solution to the quadratic equation 5x2 + 10x - 5 = 0?
x = -1 -√2, x = -1 + √2
x = -1 -√5, x = -1 + √5
x = 1 -√2, x = 1 + √2
x = -1 -√201, x = -1 + √201
The value of solution of quadratic equation 5x² + 10x - 5 = 0 is,
⇒ x = - 1 ± √2
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
Equation is,
5x² + 10x - 5 = 0
Now, We can solve by using quadratic formula as;
⇒ x = - 10 ± √10² - 4×5×- 5 / (2×5)
⇒ x = - 10 ± √100 + 100 / 10
⇒ x = - 10 ± √200 / 10
⇒ x = - 1 ± √2

which graph shows the inequality n>2
What is the area of a parallelogram whose vertices are A(−1, 12) , B(13, 12) , C(2, −5) , and D(−12, −5) ?
Answer: The area of the parallelogram with the given vertices=238 square units.
Step-by-step explanation:
Let CD be the base of the parallelogram ABCD is given by distance formula
CD=[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} =\sqrt{(-12-2)^2+(-5-(-5))^2} =\sqrt{196} =14[/tex]units[or you can count distance by using graph as ordinates of C and D are same to we can count the distance of x from C to D]
Now consider P a point on CD such that AP become the height of the parallelogram which is given by (from the graph attached)=17 [as abscissa of P and A are same to we can count the distance of y from A to P]
Area of parallelogram = base × height=14×17=238 square units.
Your height can be represented by a function h , where the input is your age.

One sample has n = 5 scores and the second has n = 10 scores.if the pooled variance for the two sample is 30, then what is the value of the estimated standard error for the sample mean difference?
The estimated standard error for the mean difference between two samples with sizes of 5 and 10 respectively, and a pooled variance of 30, is calculated using the standard error formula. The standard error is 3.
Explanation:The question you've asked falls under the realm of statistics, in specific it involves the calculation of the estimated standard error for differences between two sample means (one with n=5 scores and the second with n=10 scores) given a pooled variance of 30.
The formula to find the estimated standard error for a difference between two sample means is:
SE = sqrt[(s1^2/n1) + (s2^2/n2)]
Where s1^2 and s2^2 are the variances of the two samples and n1 and n2 are the sizes of two samples respectively. As we do not know the variances for the individual samples, we can use the pooled variance as an estimate. The pooled variance can be considered as s1^2 = s2^2 = 30.
Now substitute these values in the equation, we get:
SE = sqrt[(30/5) + (30/10)] = sqrt[6+3] = sqrt[9] = 3
So, the estimated standard error for the mean difference between these two samples is 3.

Phoebe, Andy and Polly share £270.
Phoebe gets 3 times the amount as Andy who gets twice as much as Polly.
Work out how much they get each
Phoebe got £180, Andy got £60 and Polly got £30
The amount shared is given as:
Amount = £270
Represent Phoebe's share with x, Andy's with y and Polly's with z.
From the question, we have:
x = 3y
y = 2z
So, we have:
x : y : z = 3y : 2z : z
This gives
x : y : z = 6z : 2z : z
When £270 is shared in the above ratio, we have:
x : y : z = 180 : 60 : 30
Hence, Phoebe got £180, Andy got £60 and Polly got £30

Isaac and his sister plan to surprise their parents by buying them each a pair of shoes. They agree that Isaac will pay 68% of the price since he receives a greater allowance. Use an estimation strategy to determine how much Isaac will pay if the total bill is $97.65. Show the step-by-step process you used to solve the problem.
for estimating round both the price of shoes and the percentage to round numbers
97.65 is close to 100, so use 100 for the price of shoes
68% is close to 70 so use 70%
then multiply 100 by 70 %,
100 *70% = 70 dollars
so Isaac would pay around 70 dollars
Step-by-step explanation:
first you need to see how much his sister is paying and she is paying 32% and that is 31.24 then you need to subtract 97.65 by 31.24 which will equal 66.41 so Isaac will pay $66.41 hope this helps if your going to use it change the wording up a bit
