Find the distance (8,-7) (-4,-2)
Distance = 13 units
Point A: (8, -7)
Point B: (-4, -2)
[tex]\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }[/tex]
[tex]\sqrt{(12)^{2} + (-5)^{2} }[/tex]
[tex]\sqrt{144 + 25 }[/tex]
[tex]\sqrt{169}[/tex]
[tex]13[/tex]
Answer:
[tex]\boxed {d = 13}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you find the distance between the two following points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the two following onto the formula:
[tex](x_{1}, y_{1}) = (8, -7)[/tex]
[tex](x_{2}, y_{2}) = (-4, -2)[/tex]
[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]
-Solve for the distance:
[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]
[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]
[tex]d = \sqrt{144 + 25}[/tex]
[tex]d = \sqrt{169}[/tex]
[tex]\boxed {d = 13}[/tex]
Therefore, the distance is [tex]13[/tex].
There are 4 quarters in 1 dollar the total number of dollars is a function of the number of quarters does this situation represent a linear or nonlinear function? Explain why
Answer:
sample answer: If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4
Step-by-step explanation:
The situation is a representation of the linear function.
What is meant by linear function?A linear function is one that, when graphed, produces a straight line. Thus, non-linear functions are any non-linear functions. Although graphing is the quickest way to determine whether a function is linear or non-linear, we can also determine linearity from its input/output table or equation. A straight line on the coordinate plane is represented by a linear function. For example, y = 3x - 2 denotes a straight line on a coordinate plane and, as such, a linear function.Given that,
One dollar is divided into four quarters.
The total number of dollars is a function of the number of quarters.
Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value
As a result, the slope should be 1/4.
y = 1/4x should be the linear function.
Hence, As a result, we can conclude that the situation is a linear function.

the grade 8 has hired a disk jockey the disk jockey takes 85$ plus 2 for each student that attends. The disk jockey was paid 197 how many students attended
Answer:
56 students
Step-by-step explanation:
The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.

D
Step-by-step explanation:
it is D because you always want x to be a lone fraction and that would be the first step im 99% sure unless someone can correct me :)
Answer:
d) subtract 15 from both sides
Step-by-step explanation:
Process of elimination:
a) 2.5 and x are being multiplied, not subtracted, so (a) is wrong right off the bat.
b) you may divide 2.5 by both sides, but you want to get "x" on one side first. So you would do (b) first either.
c) to get rid of 15, which we need to somehow, we need to do the opposite operation than the one in the equation. 15 is +15, not negative, and so you would need to subtract to get rid of 15. This is why (c) is also wrong.
That leaves us, with (d), because you need to subtract 15 to isolate "x".

Two angles are supplementary. One measures 3x-2 and the other measures 2x+7 Find the value of x and the measure of the smaller angle.
Sum of two angles that are supplementary = 180°
Then :-
[tex]3x - 2 + 2x+ 7 = 180[/tex]
[tex]5x + 5 = 180[/tex]
[tex]5x = 180 - 5[/tex]
[tex]5x = 180 - 5[/tex]
[tex]5x = 175[/tex]
[tex]x = \frac{175}{5} [/tex]
[tex]x = 35[/tex]
Which means :-
The measure of the larger angle :-
= 35 × 3 - 2
= 105 - 2
= 103°
The measure of the smaller angle :-
= 2 × 35 + 7
= 70 + 7
= 77°Therefore , the value of x = 35 and the measure of the smaller angle = 77° .

Mr green Drove 100 mies in 2 hours he continues to drive the same speed how long will mr green take to drive 400 more miles
Answer:
It would take him 8 hours
Since every 50 miles takes 1 hour
━━━━━━━☆☆━━━━━━━
▹ Answer
8 Hours
▹ Step-by-Step Explanation
First, find the unit rate:
100 miles ÷ 2 hours = 50 mph
Now, we need to find the time it takes to drive 400 miles so we will divide:
400 miles ÷ 50 mph = 8 hours
If you are looking for total hours, you would add:
2 hours + 8 hours = 10 hours
If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.
Hope this helps!

The frequency vibrations for a certain guitar string When is blood can be determined by the equation below, Where F is the number of vibration per second and T is measured in pounds.If the frequency of the vibrations is 600 vibrations per second, How many pounds of tantrums was used to plug the string? F = 200sqrt(T)
Answer:
9 poundsStep-by-step explanation:
Given the frequency vibrations for a certain guitar string modeled by the equation
F = 200√T where:
T is amount of tantrums in pounds
If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:
600 = 200√T
Divide both sides by 200
600/200 = 200√T /200
3 = √T
Square both sides
3² = (√T)²
9 = T
T = 9
Hence 9 pounds of tantrum was used to plug the string

The sum of two consecutive numbers is 63. Find the two numbers.
Answer:
the two numbers are 31 and 32.
Step-by-step explanation:
x+(x+1)=63
2x+1=63
2x=62
x=31
The answers are 31 and 32
The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get
x + x+1 = 63
Simpifying, you get
2x+1 = 63
Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.
2x=62
Lastly, you need to divide both sides by 2, making making the equation
x=31
The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.
