Answer:
HJ = 15Step-by-step explanation:
To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5), we will use the formula for calculating the distance between two points as shown;
D = √(x₂-x₁)²+(y₂-y₁)²
From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5
HJ = √(8-(-1))²+(-5-7)²
HJ = √(8+1)²+(-12)²
HJ = √81+144
HJ = √225
HJ = 15
Hence the length of segment HJ is 15 units

Answer:
5
Step-by-step explanation:
14, 13, 12, 11, 10, 9.
5+4 = 9
Answer:
5
Step-by-step explanation:
You're given 14 - [something] = 5 + 4.
You can start out by making sure you understand what you see.
If fourteen minus a number equals five plus four, you can start out by adding five and four together, right?
And you can figure out that 5 + 4 = 9.
So now, the question is just asking you to find a number such that when you subtract it from 14, you get 9:
14 - [something] = 9
Now you can just think about this. Fourteen minus what equals 9?
You can just count down: 14, 13, 12, 11, 10, 9. You counted down five times to get to 9, so the missing number is 5.
Or, you can also think like this:
You know that 10 is just one more than 9.
14 - 4 = 10. So 14 minus what is 9? 14 - 5 = 9 It has to be 5!
1 gallon is around 3.8 liters. State this as a ratio of liters to gallons, in the form a:b. Give your answer in simplest form
The ratio of liters to gallons in simplest form is 5 : 19.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, 1 gallon is around 3.8 liters.
So, The ratio of liters to gallons in a : b form is 1 : 3.8
Or, 10 : 38,

Write an equation of the line that passes through
the given point and has the given slope.
(1/2,4),m = -8
Answer:
The answer is
y = - 8x + 8Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
[tex]y - y _{1} = m(x - x _1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is
(1/2,4) and slope m = -8
The equation of the line is
[tex]y - 4 = - 8(x - \frac{1}{2} ) \\ y - 4 = - 8x + 4 \\ y = - 8x + 4 + 4[/tex]
We have the final answer as
y = - 8x + 8Hope this helps you

If the square root of a number is equal to twice the same number what is the number?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
let the number be x , then
[tex]\sqrt{x}[/tex] = 2x ( square both sides )
x = (2x)² = 4x² ( subtract x from both sides )
4x² - x = 0 ( factor out x from each term )
x(4x - 1) = 0
Equate each factor to zero and solve for x
x = 0
4x - 1 = 0 ⇒ 4x = 1 ⇒ x = [tex]\frac{1}{4}[/tex]
Assuming x > 0 then the number is [tex]\frac{1}{4}[/tex]
As a check
[tex]\sqrt{\frac{1}{4} }[/tex] = [tex]\frac{1}{2}[/tex] and 2 × [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{2}[/tex]

A computer had 2 gigabytes of data stored on it when Jackie bought it, and she is storing an additional 3.5 gigabytes per year, as shown in the table below. Which of these statements is correct about the linear function that represents this situation? Amount of Data Stored on Jackie’s Computer Time (year) 0 1 2 3 4 Gigabytes of Data 2 2 + 3.5 = 5.5 5.5 + 3.5 = 9 9 + 3.5 = 12.5 12.5 + 3.5 = 16 The initial value represents the 2 gigabytes of data stored on the computer when Jackie bought it, and the rate of change represents the 3.5 gigabytes per year that Jackie is storing. The initial value represents the 2 gigabytes per year that Jackie is storing, and the rate of change represents the 3.5 gigabytes of data stored on the computer when Jackie bought it. The initial value represents the 3.5 gigabytes of data stored on the computer when Jackie bought it, and the rate of change represents the 2 gigabytes per year that Jackie is storing. The initial value represents the 3.5 gigabytes per year that Jackie is storing, and the rate of change represents the 2 gigabytes of data stored on the computer when Jackie bought it. Mark this and return
Answer:The initial value represents the 2 gigabytes of data stored on the computer when Jackie bought it, and the rate of change represents the 3.5 gigabytes per year that Jackie is storing.
The statement first is correct because 2GB represents the initial data and in the second term 3.5GB represents the rate of change of data per year.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
Initial data when Jackie bought = 2 gigabytes
Rate of change of data per year:
[tex]\rm\frac{dB}{dt} = 3.5[/tex]
We can frame a linear function such that:
[tex]\rm y = 2 + n(\frac{dB}{dt})[/tex]
[tex]\rm y = 2 + 3.5n[/tex]
Where y represents the total data stored at n years.
And n represents the [tex]\rm n^{th}[/tex] year
When n = 0 then y = 2 (initial data when Jakie bought it)
When n = 1 then y = 5.5 (after one year the amount of data Jakie's computer has)
Term 2 represents the initial data and term 3.5 represents the rate of change of data per year.
Therefore, the initial value represents the 2 gigabytes of data stored on the computer when Jackie bought it, and the rate of change represents the 3.5 gigabytes per year that Jackie is storing.

Answer:
Each friend will need to contribute $20
Step-by-step explanation:
For the problem regarding the equally distributed cost per friend to rent a go-cart track, we can simply use the following eqaution:
Cost per friend = Total cost / # of friends
We are given that the Total cost is $100 and that there are 5 friends. So let's plug this into the equation to find the cost per friend (Assuming each friend is paying an equal amount):
Cost per friend = Total cost / # of friends
Cost per friend = $100 / 5
Cost per friend = $20
Hence, each friend will need to contribute $20.

The length of a rectangular field is 45 ft greater than its width, w ft. how much fencing is needed to enclose the field and divide it into two parts as shown?
Answer:
Length of fencing needed = 4x + 45
Step-by-step explanation:
Assume;
Width of rectangle = x
So,
Length of rectangle = x + 45
Find:
Length of fencing needed
Computation:
Length of fencing needed = 2(l+b) + b
Length of fencing needed = 2(x+45+x) + x
Length of fencing needed = 2(2x+45) + x
Length of fencing needed = 4x + 45
