Slope-Intercept Form: y = mx + b
m - slope b - y-interceptThe y-intercept is the y value when x = 0.
Another way to reword that is when the graph crosses the y-axis.
The x-intercept is the x value when y = 0.
Another way to reword that is when the graph crosses the x-axis.
Step-by-step explanation:
Step 1: Define equation
x - y = 3
Step 2: Convert to slope-intercept form
Subtract x on both sides: -y = 3 - xDivide both sides by -1: y = x - 3Step 3: Find x/y-intercepts
x-int
Set y = 0: 0 = x - 3Add 3 to both sides: 3 = xRewrite: x = 3Write coordinates: (3, 0)y-int
Set x = 0: y = 0 - 3Subtract: y = -3Write coordinates: (0, -3)Answer:

If option A is 20 dollar payment and option B requires 50 dollar payment. The opportunity cost of option A would be ------- and option B would be --------. a) nothing and 30 dollars. b) 70 dollar and nothing c) 30 dollar and nothing
Answers
Answer:
a) nothing and 30 dollars.
Step-by-step explanation:
Opportunity cost usually arises when faced with choices or alternatives such that one has to be chosen, while the other is forgone. The benefits forgone by choosing a certain option of the available choices is called opportunity cost.
Given that :
Option A requires $20 payment
Option B requires $50 payment
Opportunity cost of choosing A = nothing (since payment required for the other alternative is higher than the chosen option)
Opportunity cost of Choosing B = ($50 - $20) = $30 (By choosing option B over option A, $30 was forgone as the other option (option A requires $30 lesser payment)

Hint :
Equilateral triangle has same sides and same angles.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Suppose that one of the angles has a measure of y .
So angles are : y , y and y
_________________________________
Sum of the interior angles of any triangle is 180° .
_________________________________
According above :
[tex]y + y + y = 180°[/tex]
[tex]3y = 180°[/tex]
Divide sides by 3
[tex] \frac{3y}{3} = \frac{180}{3} \\ [/tex]
[tex]y = 60°[/tex]
We found that the measure of the angles are equal , so this is the measure of all three angles.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Question gave us one of the angles as
4x -12 .
So ;
[tex]4x - 12 = 60[/tex]
Add sides 12
[tex]4x - 12 + 12 = 60 + 12[/tex]
[tex]4x = 72[/tex]
Divide sides by 4
[tex] \frac{4x}{4} = \frac{72}{4} \\ [/tex]
[tex]x = \frac{9 \times 2 \times 4}{4} \\ [/tex]
[tex]x = 9 \times 2[/tex]
[tex]x = 18[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
We found that sides are same ,
So :
[tex]BZ = DB = DZ = 7x + 119 \\ [/tex]
Thus :
[tex]DB = 7x + 119[/tex]
[tex]DB = 7(18) + 119[/tex]
[tex]DB = 126 + 119[/tex]
[tex]DB = 245[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
The correct answer is Option three .

Step-by-step explanation:
Starting from the point-slope equation ...
y -y1 = m(x -x1)
Solving for y gives ...
y = mx +(y1 -m·x1)
So, the slope-intercept form equation is fairly easily found:
y = mx +b . . . . where m = m, and b = y1-m·x1
This is the equation we have used for 'b' in the attached spreadsheet.
__
Of course, the formula for slope is ...
m = (y2 -y1)/(x2 -x1)
This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)
__
The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)
_____
I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:
y = mx +b
1. y = 2x -7
3. y = 2/3x +4
8. y = 1/3x -5
9. y = -5/2x +4

Peter cuts lawns and makes $40 per lawn. He spends $10/day in work expenses. Write an equation in the form y = mx + b to represent this situation.
Answers
Answer: y= 40x-10 , where = number of lawns.
Step-by-step explanation:
In linear equation y= mx+b with one variable x, m= slope , b= y-intercept.
[Slope rate of change of y with respect to x, y-intercept = initial value of y at x=0]
Given: Peter cuts lawns and makes $40 per lawn.
let x = number of lawns
i.e. slope = $40
He spends $10/day in work expenses.
i.e. y-intercept = -10 [for each day]
So equation becomes : y= 40x-10 , where = number of lawns.

What is the axis of symmetry of this function?
Answers
Answer: 1st question• (-3, -45)
2nd question• x= -3
Step-by-step explanation:
just did it on edge
The vertex of the function p(x) = 30x^2 + 5x^2 is (-3,-45), and it is a minimum
The description of the functionThe function is given as:
p(x) = 30x^2 + 5x^2
The description of the function is that the function is a quadratic function
The vertex
From the question, we have:
p(x) = 5(x + 3)^2 – 45
A quadratic function represented as: p(x) = a(x - h)^2 + h has the vertex (h,k)
This means that the vertex is (-3,-45), and it is a minimum because a is positive i.e. a = 5
The axis of symmetryThis is the x-coordinate of the vertex.
Hence, the axis of symmetry is x = -3

John is 1.6 m tall. robbin is 156 cm tall what is the ratio of johns' height to robbins height?
Answers
Answer:
johnns height 4cm to Robin's height
The ratio of John's height to Robin's height is 20:19.
To find the ratio of John's height to Robin's height, we need to convert their heights to the same unit of measurement. Let's convert Robin's height from centimeters to meters:
Robin's height = 156 cm = 156/100 m = 1.56 m
Now that both heights are in meters, we can calculate the ratio:
John's height: Robin's height = 1.6 m : 1.56 m
To simplify the ratio, we can divide both heights by the same value:
1.6 m : 1.56 m = (1.6/0.08) m : (1.56/0.08) m = 20 : 19
Therefore, the ratio of John's height to Robin's height is 20:19.
