Answers
Answer:
-1/2
Step-by-step explanation:
In a linear relationship, the rate of change of one variable with respect to the other is constant. When we talk about change, we're looking for a difference of values.
If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the rate of change is the number we get by dividing one of these by the other.
The rate of change we're used to seeing, sometimes called the slope, is Δy/Δx. So, using the values we've already found:
[tex]\Delta{x}=2\\\Delta{y}=-1\\\Delta{y}/\Delta{x}=-1/2[/tex]

Answers
Answer:
y=¼x
Step-by-step explanation:
Parallel lines have the same slope
The slope of the given line is ¼,thus,
y-¼x+7=0
y=¼x-7
Now using the point-slope form y-y1=m(x-x1)
y-1=¼(x-4)
4y-4=x-4
4y=x-4+4
4y=x
y=¼x

Brenda is selling two different not mixes as snacks. Mix A has 3 oz. of cashews and 7 oz. of almonds. Mix B has 6 oz. of cashews and 5 oz. of almonds. Which inequalities represent the number of mix A mixes, and mix B mixes, B, Brenda can make if she has 72 oz. of cashews and 84 oz. of almonds.
Answers
Answer:
Mix A ≤ 12
Mix B ≤ 12
Step-by-step explanation:
Mix A requires 3 oz of cashews and 7 oz of almonds
Mix B requires 6 oz of cashews and 5 oz of almonds
If Brenda makes just Mix A using the available 72 oz of cashews and 84 oz of almonds
With 72 oz of cashews, she would potentially make 72/3=24 Mix A snacks
With 84 oz of almond, she would potentially make 84/7=12 Mix A snacks
Since she would require both cashews and almonds to make Mix A snacks, she would be able to make 12 mix A snacks
Inequality would be:
Mix A ≤ 12
If Brenda makes just Mix B using the available 72 oz of cashews and 84 oz of almonds
With 72 oz of cashews, she would potentially make 72/6=12 Mix B snacks
With 84 oz of almond, she would potentially make 84/5=16 (approximately) Mix B snacks
Since she would require both cashews and almonds to make Mix B snacks, she would be able to make 12 mix B snacks
Inequality would be:
Mix B ≤ 12

Answers
Answer:
point A is located at (-2,5) and point B is located at point (5,5), the distance between the points is 7 units. hope this helps!
The distance between the points will be 7 units. Point A is located at the point (-2, 5). Point B is located at the point (5, 5).
What is distance between points?The formula of distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: [tex](A,B) = \sqrt{( x_{2} - x_{1} )^2 + ( y_{2} - y_{1})^2}[/tex]
We have,
Point A (-2, 5) and Point B (5, 5).
i.e.
x₁ = -2, x₂ = 5 and
y₁ = 5, y₂ = 5
Now,
Using the above mentioned formula of distance,
i.e.
Distance [tex](A,B) = \sqrt{( x_{2} - x_{1} )^2 + ( y_{2} - y_{1})^2}[/tex]
So,
Substituting values,
Distance [tex](A,B) = \sqrt{(5-(-2) )^2 + ( 5-5)^2}[/tex]
Now, simplify,
Distance [tex](A,B) = \sqrt{(7)^2 + 0}[/tex]
We get,
Distance [tex](A,B) = 7[/tex]
So, the distance between AB is 7 units.
Hence, we can say that the distance between the points will be 7 units. Point A is located at the point (-2, 5). Point B is located at the point (5, 5).

A movie theater has 400 seats. Tickets at the theater cost $8 for students, $10 for adults, and $7 for senior citizens. On a night when all the seats were sold, the theater made $3,535 from ticket sales. If the number of adult tickets sold was 10 less than the number of student and senior tickets combined, how many senior tickets were sold?
55 senior tickets
150 senior tickets
195 senior tickets
255 senior tickets
Answers
Answer:
55 senior tickets
Step-by-step explanation:
400 seats
students: $8
Adults: $10
Seniors: $7
All seats were sold and the total money they got was $3,535
Adult tickets sold was 10 less than the # of student and seniors combined.
8a+10b+7c=3535
a+b+c=400 now just solve for them
8a+10b+7c=3535
-8a-8b-8c=-3200
2b-c=335...
If you solve for the numbers, you'll get 55 tickets.

How many four digit numbers can be formed using the digits 7, 6, 5 and 2 if
repetitions are allowed?
Answers
Answer: The number of four digit numbers can be formed using the digits 7, 6, 5 and 2 = 256
Step-by-step explanation:
Given digits = 7, 6, 5 and 2
If repetition is allowed , we can use Fundamental principal of counting.
By this principal , total four digit numbers can be formed = 4x 4x4 x 4 [∵ choice for each place = 4 ]
= 256
Hence, the number of four digit numbers can be formed using the digits 7, 6, 5 and 2 = 256

Pip was thinking of a number. Pip doubles it, then adds 6 to get an answer of 13.8. What was
the original number?
Answers
Answer:
The original number is 3.9.
Step-by-step explanation:
With the information given, you can write an expression where the number multiplied for 2 plus 6 is equal to 13.8:
2x+6=13.8, where x is the original number
Now, you can solve for x to find the original number:
2x=13.8-6
x=7.8/2
x=3.9
According to this, the answer is that the original number is 3.9.
