Jacob wants to buy shirts online. Each shirt costs 200 pesos. The
shipping cost is 120 pesos. Write the linear equation representing the
following:
1. Total cost that Jacob will pay after ordering the shirt in slope-
intercept form?
2. Total cost that Jacob will pay after ordering the shirt in standard
form?
Answer:
1) y = 200x + 120
2) - 200x + y = 120
Step-by-step explanation:
Equation of the line
The equation of the line in standard form is:
Ax + By = C
Where A, B, and C are constants.
The equation of the line in slope-intercept form is:
y = mx + b
Being m the slope and b the y-intercept.
1)
Each shirt costs 200 pesos. Let's assume Jacob purchases x shirts. The cost of the shirts alone is 200x.
Assuming the shipping cost is 120 regardless of the purchased shirts, then the total cost is:
y = 200x + 120
This is the slope-intercept form of the line.
2) Rearranging the above equation:
- 200x + y = 120
It's the standard form of the line
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.
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 Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y=2y+1/5
Now, solving for y
y- 2y= 1/5
-y= 1/5
y= -1/5
Hence, the value of y is -1/5.

How many 4-digit numbers can you write if you can use only digits 1 and 2?
Answer:
Step-by-step explanation:
Thus if you are not allowed to repeat a digit the number of possible 4 digit numbers you can construct from 1,2,3,4 is 4 3 2 1 = 24.
The number of 4-digit numbers can you write if you can use only digits 1 and 2 is 16.
Given that, using only digits 1 and 2 form 4-digit numbers.
What is digit formation?Digits are the single symbols used to represent numbers in Maths. For example, in number 89, 8 and 9 are two digits. Hence, the numerals such as 0, 1, 2, 3,4, 5,6,7,8,9, and 0 are the form of digits which are used to represent a combination of numbers and do arithmetic operations in our day to day life.
Here,
For the first digit you are picking from 2 digits.
For the second digit you are picking from 2 digits.
For the third digit you are picking from 2 digits.
For the fourth digit you are picking from 2 digits.
2×2×2×2=16
4-digit numbers
1111, 2111, 1211, 1121, 1112, 1221, 2112, 1122, 2211, 1212, 2121, 2221, 1222, 2122, 2212 and 2222.

The mean of 4 numbers is 40 what is the sum of the 4 numbers
Answer:44.445
Step-by-step explanation:
Let the 5 numbers are a,b,c,d, and e
so (a+b+c+d+e)/5=40
So a+b+c+d+e=5*40=200
Now let the next 4 no are p,q,r,s then
(p+q+r+s)/4=50
p+q+r+s=200
Thus sum of all 9 numbers
=(a+b+c+d+e) +(p+q+r+s)
=200+200=400
thus average of these 9 numbers
If the mean of 4 numbers is 40. Then the sum of the numbers will be 160.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.
The mean of 4 numbers is 40.
Mean = (Sum of the number) / (Number of the observation)
Mean = 40
Number of the observation = 4
Then the sum of the numbers will be
40 = (Sum of the number) / 4
Sum of the numbers = 160

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]

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
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)
John is 1.6 m tall. robbin is 156 cm tall what is the ratio of johns' height to robbins height?
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.

What is the axis of symmetry of this function?
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

Answer:
see below
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
