Find the slope of AB: A(-2, 5) and B(6.-1)
Answer:
Step-by-step explanation:
y2- y1/x2-x1
-1-5/6-2
-6/8
The required slope of AB is -3/4 which passes through points A(-2, 5) and B(6.-1).
What is the slope of the line?The slope of the line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
To determine the slope of AB: A(-2, 5) and B(6.-1)
Given,
We have been given that two points are A(-2, 5) and B(6.-1)
Let
x₁ = -2, y₁ = 5
x₂ = 6, y₂ = -1
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute values in the formula
The slope of AB = (-1 - 5)/(6 - (-2))
The slope of AB = (-6)/(6 + 2)
The slope of AB = -6/8
Therefore, the required slope of AB is -3/4.

help please ahahah i hate this sm i really need help
Answer:
-7/6
Step-by-step explanation:
- take two values of x and their corresponding two values of y
- use the slope formula ( y2 - y1 )/( x2 - x1 )
- i used x values 4 and 10 but you can use any
( -6 - (-13) ) / ( 4 - 10 ) = -7/6
Chloe makes a long distance call from a pay phone, the first minute of a call cost $2.30. After that, each additional minute is $0.20. How many minutes can Chloe talk for $4.30?
Answer:
The number of minutes is 10minutes
Step-by-step explanation:
Step one:
Given that the first minute of a call cost $2.30 and
each additional minute is $0.20.
let the number of minutes be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that y=4.3, we can solve for the totals cost as
by substituting we have
4.3=0.2x+2.3
4.3-2.3=0.2x
2=0.2x
x=2/0.2
x=10
The number of minutes is 10minutes
The post office sold 39-cent
commemorative stamps in sheets
of 25 stamps. What was the price
for the sheet of stamps?
Answer: $9.75.
Step-by-step explanation:
Given: Cost per stamp = 39 cents
since 1 dollar = 100 cent , so 1 cent = 0.01 dollar
So, Cost per stamp = $0.39
Total stamps = 25
Cost of 25 stamps = (Cost per stamp) x (Cost per stamp)
=$0.39 x 25
= $9.75
Hence, the price for the sheet of stamps = $9.75.

340.1 ÷ 9.5 = 358
Answer:
35.8
Step-by-step explanation:
[tex]\frac{340.1}{9.5}[/tex] = 358
We know that our answer can never be greater than 358 since the dividend
is 340.1 and the divisor is 9.5;
Also,
Both values are to one decimal places and we can use this to solve the problem;
9 can divide 340 in about 37 place with a remainder of 7,
So, it is appropriate to make the solution 35.8

A rocket is 1.5miles above the earth in 20 seconds and is 8 miles above the earth in 2 minutes. What is the rockets rate of change in miles per seconds
Given:
A rocket is 1.5 miles above the earth in 20 seconds.
It is 8 miles above the earth in 2 minutes.
To find:
The rockets rate of change in miles per seconds.
Solution:
Let y be the height above the earth after x seconds.
A rocket is 1.5 miles above the earth in 20 seconds. So, the point is (20,1.5).
It is 8 miles above the earth in 2 minutes.
1 minute = 60 seconds
2 minutes = 120 seconds
So, the point is (120,8).
The rockets rate of change in miles per seconds is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{8-1.5}{120-20}[/tex]
[tex]m=\dfrac{6.5}{100}[/tex]
[tex]m=0.065[/tex]
Therefore, the rockets rate of change is 0.065 miles per seconds .

What is the discriminant of the quadratic equation, 4x^2-8x-5=0
Answer:
Step-by-step explanation:
4x^2-8x-5=0
The discriminant is the number under the √. In this case it's 144
Answer:
[tex]\Delta=144[/tex]
Step-by-step explanation:
For a quadratic in standard form, the discriminant is given by:
[tex]\Delta=b^2-4ac[/tex]
We have the equation:
[tex]4x^2-8x-5=0[/tex]
Hence, our a=4; b=-8; and c=-5.
Substituting into our formula, we acquire:
[tex]\Delta=(-8)^2-4(4)(-5)[/tex]
Evaluate:
[tex]\Delta=64+80[/tex]
Add:
[tex]\Delta=144[/tex]
Therefore, our discriminant is 144.
Notes:
Since our discriminant is a positive value, this tells us that our quadratic has two real roots.
