Calculate the slope of the line that goes through the points (-15,70) and (5,10)
The slope of the line that goes through the point (-15,70) and (5,10) is - 3.
What is slope?The slope is the measure of the angle a line has with respect to the positive x-axis.
We know when two points of a line is given slope can be obtained by rise over run where the rise is the difference between the points of the y-axis and run is the difference of the points of the x-axis.
Given points are (-15,70) and (5,10) through which a line passes.
∴ Slope(m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex].
Slope(m) = (10 - 70)/(5 + 15).
Slope(m) = -60/20.

What percent of 10 is 6?
To determine what percent of 10 is 6, you multiply 6/10 by 100, which equals 60%, thus 6 is 60% of 10.
Explanation:To find what percent of 10 is 6, we can use the formula for percentage which is (Part / Whole) * 100.
In this case, the 'part' is 6 and the 'whole' is 10.
So the equation to find the percentage is (6 / 10) * 100.
Calculating that out, we get 0.6 * 100, which equals to 60%.
Therefore, 6 is 60% of 10.
This is a basic concept in mathematics where you are trying to find out how one number compares to another in terms of percentage.

Which type of function best models the data in the table below?
A. inverse variation
B. linear
C. logarithmic
D. quadratic
Answer: Option A inverse variation
Explanation:
when we compare the values from the given table x is increasing and y is decreasing hence we can see it is an inverse variation.
In option B difference among all consecutive values of x is 2 but in y it is not same among all consecutive terms. In linear function change in y over change in x must be same.
In option C x is increasing but y is decreasing which is violating the property of logarithmic function. In logarithmic function if x increases then y should increase.
In option D first value of x is 2 following quadratic property meaning giving square of itself in y which is 4. But not all values of y are square of x except first value. In quadratic function value of y should be square of x.
The type of function that best models the table given is: A. inverse variation.
What is Inverse Variation?Inverse variation can be described as a relationship between two variables, whereby, the product of the two variables will give a constant. It is expressed as, k = xy.
In an inverse variation, if one variable increases, the other variable decreases.
The table shows an inverse variation because as x increases, y decreases, and can be expressed as k = xy.

B. is the answer!!!!!!! (-5, 0) and (6, 0) is the correct answer.Step-by-step explanation:
(-5, 0) and (6, 0) is the correct answer.
To find the x-intercepts, use the Zero Product Property and solve for x:
x - 6 = 0
x = 6
x + 5 = 0
x = -5
Therefore, the x-intercepts are (6,0) & (-5,0).

Step-by-step explanation:
You can represent the measures of an angle and its complement as x° and (90 − x)°. Similarly, you can represent the measures of an angle and its supplement as x° and (180 − x)°. Use these expressions to find the measures of the angles described. The measure of an angle is equal to four times the measure of its supplement. The measure of the angle is ° and the measure of its supplement is °.
To determine the size of an angle and its supplement when the angle is four times the size of its supplement, we use the equation x = 4(180 - x) and solve for x to find that the angle measures 144 degrees and its supplement measures 36 degrees.
To find the measures of an angle and its supplement when the angle is four times its supplement, we use the expressions x and 180 - x. We can set up the equation x = 4(180 - x). Then we can solve for x to find the measures of the angle and its supplement.
By expanding and rearranging the equation, we get:
x = 720 - 4x5x = 720x = 144Thus, the angle measures 144 degrees and its supplement measures 36 degrees (since 180 - 144 = 36).

A football team gained 6 yards on a first down, lost 15 yards on the second down, and gained 12 yards on the third down. how many yards do they need to gain on the fourth down to have a 10 yard gain from their starting position?
Answer:
They need to earn 7 yards on the fourth down to have a 10 yard gain from their starting position
Step-by-step explanation:
To gain a new set of downs, a football team has four downs(tries) to gain 10 net yards, in total.
Gained 6 yards on first down
Net of 6 yards gained
Needs 10-6 = 4 yards
Lost 15 yards on second down
6 - 15 = -9
In all, they have lost 9 yards, so they need
4 + 15 = 19 yards
Gained 12 yards on third down
-9 + 12 = 3 net yards(need 10)
19 - 12 = 7
They need to earn 7 yards on the fourth down to have a 10 yard gain from their starting position

Which relationship is continuous? A. the number of cows a farmer has owned over the years B. the number of cookies Stan baked for the party C. the number of people attending the assembly D. the distance a runner ran during training
The relationship that is continuous is the distance a runner ran during training.
Explanation:The relationship that is continuous is D. the distance a runner ran during training.
A continuous relationship is one in which the values of one variable change smoothly and consistently over a given interval. In the case of the distance a runner ran during training, the distance can be any real number and can be measured with great precision, allowing for smooth changes in the values.
The continuous relationship is the distance a runner ran during training.
A continuous relationship is one where the variable changes smoothly and can take any value within a given range. Let's analyze the options:
A. The number of cows a farmer has owned over the years:
This relationship is likely continuous, as the number of cows can change smoothly over time, and there are no discrete jumps in ownership.
B. The number of cookies Stan baked for the party:
This relationship is likely discrete, as the number of cookies is typically counted in whole numbers without smooth transitions. Stan would bake a specific, countable quantity of cookies.
C. The number of people attending the assembly:
This relationship is likely discrete, as the number of people is counted in whole numbers and does not change smoothly. Attendees come in whole individuals, not fractions.
D. The distance a runner ran during training:
This relationship is continuous, as distance can vary smoothly and take any real value within a given range. Runners can cover fractional distances, making it a continuous variable.
Therefore, the continuous relationship is D, the distance a runner ran during training.

Find the coordinates of the midpoint of the segment whose endpoints are H(8,2) and K(6,10).
The coordinates of the midpoint of the segment HK are (7, 6).
The midpoint coordinates of a line segment can be found using the midpoint formula:
Midpoint =[tex]\((\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})\)[/tex]
Given the endpoints of the segment as H(8,2) and K(6,10), let's plug these values into the formula:
Midpoint =[tex]\((\frac{8 + 6}{2}, \frac{2 + 10}{2})\)[/tex]
Midpoint =[tex]\((\frac{14}{2}, \frac{12}{2})\)[/tex]
Midpoint =[tex]\((7, 6)\)[/tex]
The coordinates of the midpoint of the segment HK are (7, 6).
To calculate the midpoint of a line segment, you can follow these steps:
1. Identify the coordinates of the endpoints of the segment. Let's call them[tex]\( (x_1, y_1) \) and \( (x_2, y_2) \).[/tex]
2. Use the midpoint formula:[tex]\( \text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \).[/tex]
3. Substitute the coordinates into the formula and calculate.
In this case, the endpoints are H(8,2) and K(6,10). Plug these values into the midpoint formula:
Midpoint = [tex]\( \left( \frac{8 + 6}{2}, \frac{2 + 10}{2} \right) \).[/tex]
Simplify the equation:
Midpoint =[tex]\( \left( \frac{14}{2}, \frac{12}{2} \right) \).[/tex]
Finally, calculate the values:
Midpoint =[tex]\( (7, 6) \).[/tex]
So, the coordinates of the midpoint of the segment HK are (7, 6).
