Hello !
Answer:
[tex] \boxed{\sf None \: of \: the \: options \text{:} \: \: m =- \dfrac{13}{3}} [/tex]
Step-by-step explanation:
The slope m of a line passing through two points can be calculated using the following formula:
[tex] \sf m = \dfrac{rise}{run} = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]
[tex] \\ [/tex]
Let (x₁ , y₁) = (2 , -7)
Let (x₂ , y₂) = (-1 , 6)
Substitute these values into our formula:
[tex] \sf m =\dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{6 - (-7) }{-1 - 2 } = \dfrac{13}{-3}\\ \\ \implies \boxed{\sf m = -\dfrac{13}{3}} [/tex]

Since you can't subtract 7 from 5 you have to carry over from the next number (4). Take from 4, that leaves 3 in its place, and now you got an extra 1, so you can subtract 7 from 15 to get 8. Now subtract 2 from that 3 to get 1. That's how you get the answer 1.81 .
It's basically a normal subtraction problem, you just have to Remember to put the decimal point in the right place.
Hope this helped :)

the sum of the measures of the angles of all triangles is 180 degrees.if one angle of the triangle measures 45 degrees,and other two angles are equal.what is the measure of the other two angles?
Answer:
67.5 degrees.
Step-by-step explanation:
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
Answer:
67.5°
Step-by-step explanation:
Given:
All triangles is 180°
One Triangle measure 45°
2 Other Angles are equal
To Find:
Two Other Angles
Solution:
180°- 45° = 135°
135° ÷ 2 = 67.5°
Therefore the other two angles are 67.5°

Write the following algebraic expression for this sentence:
"The product of eight and a number squared decreased by 5."
Answer:
8n² - 5
Step-by-step explanation:
n = 'a number'
The expression is 8x² - 5.
what is expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions. The other number is x, and a number is 6 greater than half of it. In a mathematical expression, this proposition is denoted by the expression x/2 + 6.
Given:
The product of eight and a number squared decreased by 5
let the number be x.
product of eight and a number squared
= 8x²
and decreased by 5
= 8x² - 5
hence, the expression is 8x² - 5.

Allison is going to the post office to buy 34cent stamps and 3 cent adjustment stamps. Since the current postage rate is 49 cent she will need 5 times as many 3 cent adjusment stamps as 34 cent stamps. If she has $12.25 to spend, what is the largest number of 34 cent stamps she can buy?
Determine the largest number of 34 cent stamps she can buy
The largest number of 34 cent stamps she can buy is 30
Given:
Total money = $12.25
let
x = 34 cent stamp
y = 3 cent stamp
34 cent stamp = 5 × 3 cent stamp
x + y = 0.49
x = 5y
0.34x + 0.3y = 12.25
0.35(5y) + 0.3y = 12.25
1.75y + 0.3y = 12.25
2.05y = 12.25
y = 12.25/2.05
y = 5.9756097560975
approximately, y = 6
Recall,
x = 5y
x = 5(6)
x = 30
Therefore, the largest number of 34 cent stamps she can buy is 30

Lakeside amusement park charges an entry fee plus $1.50 per ticket used to go on the rides. The entry fee is the same amount for everyone. Louisa spent a total of $30.75 on the entry fee plus 15 ride tickets. Click “show your work” below and show calculations to determine how much Louisa paid for the entry fee.
Answer:
The entry fee is $8.25
Step-by-step explanation:
Total together: $30.75
She bought 15 tickets * $1.50 cost per 1 ticket
= $22.50
$30.75 (total) - $22.50 (price of tickets)= $8.25
determine the intercepts of the line 4x-3y=17
Answer:
x-intercept = 17/4 and y = -17/3
Step-by-step explanation:
To find the intercepts: set x = 0 for the y-intercept and solve the equation and set y =0 for the x- intercept and solve the equation.
To
4x - 3y = 17
4(0) - 3y = 17
0 - 3y = 17
y = 17 /-3
y = -17/3 = -5 2/3 y-intercept = -5 2/3.
The ordered pair on the graph is (0, -17/3)
4x - 3(0) = 17
4x - 0 = 17
4x = 17
x = 17/4 x-intercept = 17/4
The ordered pair on the graph is (17/4, 0)

Answer:
y = -2/3x + 6
Step-by-step explanation:
replace the coordinates in the equation
y= mx + c
y= 8
x= -3
8= -2/3 (-3) + c
c + 2 = 8
c = 8 - 2
c = 6
y= -2/3x + 6
