Points (-2, 4) and (-1,1) lie on the same line. Which of the following equations represents the line?
A. y - 1 = -}(x + 1)
B. y - 1 = -3(x + 1)
C. y - 1 = -}(x - 1)
D. y - 1 = -3(x - 1)
Answer:
A
Step-by-step explanation:
There are 2 ways you can do this. I'll show you one!
1. Find the Slope
a. use the slope formla: (y1-y2)/(x1-x2)
(4-1)/(-2-1)= 3/-3= -1
This eliminates both B and D, as their slopes are -3
2. Now analyze the last 2 equations
a. A goes through the ordered pair (-1, 1)
b. C goes through the ordered pair (1, 1)
The line we want goes through (-1, 1), so A is the correct answer!
[tex]y-1=-3(x+1)[/tex] equation represents the line.
What is point slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point.
Given points
[tex](x_{1} ,y_{1} )[/tex] = (-1, 1)
[tex](x_{2} ,y_{2} )[/tex] = (-2, 4)
Using point slope form
We know that the equation of line passing through points [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] is
[tex]y-y_{1} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }( x-x_{1})[/tex]
Therefore equation of line passing through points (-1, 1) and (-2, 4) is
[tex]y-1=\frac{4-1}{-2+1}(x-(-1))[/tex]
[tex]y-1=\frac{3}{-1} (x+1)[/tex]
[tex]y-1=-3(x+1)[/tex]
Option B is correct.

Answer:
y = -2/3x + 3
Step-by-step explanation:
( -3, 5)
Parallel slope = -2/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -2/3(x + 3)
y - 5 = -2/3x - 2
y = -2/3x + 3

i put this in part B (She uses 24 applications regularly)
Answer:
24 would be the correct answer.
Step-by-step explanation:
24 would be the correct answer because 2/3 x 18 + 12 = 24.
Making 2/3 the the fraction that was used and already installed.
Making 18 the number of the already installed applications
Making 12 the number of the additional installed applications.

what is a sequence? How do I determine if a sequence is arithmetic or geometric?
Answer: Ok So Compute successive differences of the terms. If they are all the same, the sequence is arithmetic and the common difference is the difference you have found. If successive pairs of differences have the same ratio, the sequence is geometric The common pattern in an arithmetic sequence is that the same number is added or subtracted to each number to produce the next number. This is called the common difference. The common pattern in a geometric sequence is that the same number is multiplied or divided to each number to produce the next number.and the common ratio is the ratio you have determined.
Hope this helps have a awesome day❤️

what is the value of x in the diagram below?
Answer:
x = 45
Step-by-step explanation:
These two angles are consecutive interior angles. This means they will add up to 180°. We use this information to make an equation.
x + 5 + 130 = 180
x + 135 = 180
x = 45

Almonds cost $5 per pound. Cashews cost $2 per pound. Matt purchased
a container of almonds and cashews that sells for $3 per pound. The label
was torn and says that there are 10 pounds of cashews in the container.
How many pounds of almonds are in the container?
A 5 pounds
B 10 pounds
C 15 pounds
D 25 pounds
Answer:
B 10 pounds
Step-by-step explanation:
Start with what you know. You know that almost 5 dollars per pound. and that cashews cost 2 dollars per pound. If there are 10 pounds of cashews, that is 20 dollars worth of cashews. then if you use your head you will figure out that there are 10 pounds.

The cost of a plane ticket varies directly as the number of miles in the trip. A 3000 mile trip costs $400. What is the cost of a 450 mile trip
Answer:
$60
Step-by-step explanation:
set up a proportion and cross-multiply:
3000/400 = cost/450
c = cost
3,000c = 180,000
c = 180/3
c = 60
Price of the ticket of 450 mile trip = $60.
What is Division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. It is an operation used for equal grouping and equal sharing in math. Division is the opposite of multiplication.
Division Math Formula
The four important terms used in the division operation are dividend, divisor, quotient and remainder. The formula to calculate the division of two numbers is:
Dividend ÷ Divisor = Quotient + Remainder.
Given,
Ticket cost of 3000 mile trip = $400
Ticket cost of 1 mile trip = $400/3000
Ticket cost of 450 mile trip = $400 × 450 /3000
= $60
Hence, the cost of 450 mile trip is $60.
