-7 - (-8) = 1
6-4=2
Slope is 1/2
The slope of the line through (6, -7) and (4, -8)
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
where (x₁, y₁) and (x₂, y₂) are the two points that you are trying to find the slope between.
Given;
Two points; (6, -7) and (4, -8)
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m=(-8-(-7))/(4-6)
m=(-1)/-2
m=1/2
Therefore, the slope between the two given points will be1/2

Solve the equation: 3x − x − 5 = 2(x + 2) − 9 No solution, 1, All real numbers, 0
Answer:
I hope this helps
Step-by-step explanation:
Simplifying
3x + -1x + -5 = 2(x + 2) + -9
Reorder the terms:
-5 + 3x + -1x = 2(x + 2) + -9
Combine like terms: 3x + -1x = 2x
-5 + 2x = 2(x + 2) + -9
Reorder the terms:
-5 + 2x = 2(2 + x) + -9
-5 + 2x = (2 * 2 + x * 2) + -9
-5 + 2x = (4 + 2x) + -9
Reorder the terms:
-5 + 2x = 4 + -9 + 2x
Combine like terms: 4 + -9 = -5
-5 + 2x = -5 + 2x
Add '5' to each side of the equation.
-5 + 5 + 2x = -5 + 5 + 2x
Combine like terms: -5 + 5 = 0
0 + 2x = -5 + 5 + 2x
2x = -5 + 5 + 2x
Combine like terms: -5 + 5 = 0
2x = 0 + 2x
2x = 2x
Add '-2x' to each side of the equation.
2x + -2x = 2x + -2x
Combine like terms: 2x + -2x = 0
0 = 2x + -2x
Combine like terms: 2x + -2x = 0
0 = 0
Solving
0 = 0
Couldn't find a variable to solve for.

If 3 tickets to a certain show cost $13.20, what would 7 tickets cost?
What is this answer?
Answer:
$ 30.8Step-by-step explanation:
ratio and proportion:
3 tickets = 7 tickets
$13.20 x
then cross multiply: 3 (x) = 13.20 (7)
simplify: 3x = 92.4
solve for x = 92.4 / 3
x = $ 30.8
therefore,
7 tickets costs $ 30.8

Veronica takes of an hour to write of a page of calligraphy.
How long will it take Veronica to write one page of calligraphy?
Using proportions, it is found that it will take Veronica 4/3 of an hour to write one page of calligraphy.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, it is found that she takes 1/3 of an hour to write 1/4 of a page of calligraphy. How long it takes her to write a page?
The rule of three is:
1/3 hour - 1/4 page
x hours - 1 page
Applying cross multiplication:
[tex]\frac{x}{4} = \frac{1}{3}[/tex]
[tex]x = \frac{4}{3}[/tex]
It will take Veronica 4/3 of an hour to write one page of calligraphy.

together.
Answer:
08:30 am
Step-by-step explanation:
30 * 1 =30 24 * 1 = 24
30* 2 = 60 24 * 2 = 48

10s - 5 = 20
Value of s
Answer:
2.5
Step-by-step explanation:
10s-5=20
(add 5 to both sides)
10s=25
(divide both sides by 10)
s=2.5
Answer:
s = 2.5
Step-by-step explanation:
you need to figure out what multiplied by 10 will give you 25, because then you have to subtract 5 in the second part of the equation to get 20.
10 multiplied by 2.5 equals 25, so s = 2.5

What are the first 4 terms use the explicit rule:
f(n)= 3n-1
(show your work)
Answer:
25811Step-by-step explanation:
We are given the rule [ f(n) = 3n - 1 ] and n represents the term.
First term:
f(n) = 3n - 1
f(1) = 3(1) - 1
f(1) = 3 - 1
f(-1) = 2
Second term:
f(n) = 3n - 1
f(2) = 3(2) - 1
f(2) = 6 - 1
f(2) = 5
Third term:
f(n) = 3n - 1
f(3) = 3(3) - 1
f(3) = 9 - 1
f(3) = 8
Fourth term:
f(n) = 3n - 1
f(4) = 3(4) - 1
f(4) = 12 - 1
f(4) = 11
As you can see, the common difference is 3.

Answer:
x = 133 x = -7
Step-by-step explanation:
| x/7 - 9| = 10
There are two solutions, one positive and one negative
x/7 - 9 = 10 x/7 - 9 = -10
Add to to each side
x/7 - 9+9 = 10+9 x/7 - 9+9 = -10+9
x/7 = 19 x/7 = -1
Multiply each side by 7
x/7 *7 = 19 *7 x/7*7 = -1*7
x = 133 x = -7
