Given:
(2, 4) and (3, 3) are on the line.
To find:
The equation of line in point slope form.
Solution:
If a line passes through a point [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
(2, 4) and (3, 3) are on the line. So, slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-4}{3-2}[/tex]
[tex]m=\dfrac{-1}{1}[/tex]
[tex]m=-1[/tex]
The slope of a line is -1 and it passes through (2,4). So, an equation in point slope form is
[tex]y-4=-1(x-2)[/tex]
Therefore, an equation of the line in point slope form is [tex]y-4=-1(x-2)[/tex].

Step-by-step explanation:
A department store buys 300 shirts for a total cost of 7,200 and sells them for $30 each. Find the percent markup.
Step-by-step explanation:
7200 ÷ 300 = 24
30 - 24 = 6
6/24 × 100/1 = 25%
The markup percent of 300 shirts is 25%.
What is Markup price?Markup price is defined as the difference of the selling price and the cost price of a product.
Markup percent can be found as,
Mark up % = profit / cost price × 100.
Given that,
The cost price for 300 shirts is 7200.
And, the selling price for each shirt is $30.
Then the selling price for all 300 shirts is 300 × 30 =$9000.
The markup percent can be found by taking the ratio of the difference of the selling and cost price to the cost price and then multiplying it by 100 as below,
Mark up percent = (Selling price - Cost price)/ Cost price × 100%
= (9000 - 7200) / 7200 × 100%
= 1 / 4 × 100%
= 25%
Hence, the percent markup is 25%.

James has 30 candies. How many kids (including James) can share these candies evenly? It has to be multiple things, I think.
Answer:
So if James has 30 candy it would be best to do it in multiple ways in my opinion, so basically you can divide it among 3 kids including James where the kids get 10 each or you can divide it among 6 kids (still including James) and they all get 5 pieces of candy! Hope this helps and stay safe :)
Step-by-step explanation:
Possible Answers:
14 kids and james- 2 candies each
9 kids and james- 3 candies each
1 kid and james - 15 candies each
4 kids and james - 6 candies each

Answer:
b = 40°
Step-by-step explanation:
Since PQ = RQ, then Δ PQR is isosceles
Thus the 2 base angles are congruent
∠ PRQ = 180° - 140° = 40° ( adjacent angles are supplementary )
Then
∠ QPR = ∠ PRQ = b = 40°
Answer:
40 degrees
Step-by-step explanation:
The image says that PQ=RQ which makes this triangle isosceles. To solve you must remember that in isosceles triangles the two base angles are always congruent. In this case, the two bottom angles are the bases. So we must first solve for m<QRP. To do this use complementary angles to make the equation m<QRP=180-140. So m<QRP=40 which means b=40 also.

How much of a 3/4 cup serving is in a 2/3 of yogurt
the graph shows function j, a transformation of
[tex]f(x) = {x}^{ \frac{1}{2} } [/tex]
replace b and h to create the equation for function j
[tex]j(x) = (bx + h) {}^{ \frac{1}{2} } [/tex]
Answer:
J(x)=(-1x+4)^1/2
Step-by-step explanation:
The value of b and h are -1 and 4 after applying the transformation to the parent function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
The graph shows function j, a transformation of f(x)
[tex]\rm f(x) =x^{\dfrac{1}{2} }[/tex]
First plot the above function on the graph paper of the coordinate plane.
From the graph,
The domain of the function f(x) is all real numbers
The range of the function f(x) is all real numbers.
As we can see in the graph of function j(x)
To find the equation for the function j(x):
Applying transformation to the function f(x)
x → (x + 4)
The function will shift 4 units right
[tex]\rm F(x) =(x+4)^{\dfrac{1}{2} }[/tex]
Applying the second transformation:
x → -x
[tex]\rm J(x)=(-x+4)^{\dfrac{1}{2}}[/tex]
The function will reflect at the line x = 2
Thus, the value of b and h are -1 and 4 after applying the transformation to the parent function.

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
54 + 61 + 5v = 180
Step 2: Solve for v
Combine like terms: 115 + 5v = 180Subtract 115 on both sides: 5v = 65Divide 5 on both sides: v = 13And we have our final answer!
Answer:
13°
Step-by-step explanation:
Neccessary information:
Total internal angles in a triangle is equal to 180°.
Method:
The first step is to add the given values of 54 and 61, this gives you 115. This is because the total internal angle in a triangle is 180°. This means that in order to work out the value of v we must add the given values to find how much of the 180° is already known.
The next step is to find the value of 5v. This can be done by subtracting 115 (Total of the values given) from 180, this gives you 65(5v). This is because we are finding how much of the 180° total is not known.
The final step is to divide the value of 5v which is 65 by 5, this gives you 13. This is because 65 is equal to 5v so to work out the value of v you would need to divide by 5.
Step by step:
1) Add 54 and 61.
[tex]54+61=115[/tex]
2) Subtract 115 from 180.
[tex]180-115=65[/tex]
3) Divide 65 by 5.
[tex]65/5=13[/tex]
