Answer:
(3, 1 ) is a solution
Step-by-step explanation:
To determine if the given points are solutions, substitute the x and y values into the left side of the equation and if equal to the right side then they are solutions.
(3, 1 )
3 + 4(1) = 3 + 4 = 7 = right side , then a solution
(2, 1 )
2 + 4(1) = 2 + 4 = 6 ≠ 7 ← not a solution
Javier will be a senior next year in high school. To celebrate his graduation, his grandmother gave him a sizeable about of money. Since he has scholarships for college, Javier decided to investigate investing the money in stocks. He talked to a consultant, who explained some of her investment types and their returns as compared to the market average. Javier’s choices were to invest in high- or low-capital stock, below average or at or above average and domestic or international. Find the probability of the following situation: P(the stock performs below average|domestic)
Probabilities are used to determine the chances of events.
The probability P(the stock performs below average|domestic) is 0.109
How to calculate the probabilityLet A represent the number of stocks that performs below average
B represents the number of domestic stock
From the table, we have:
n(A n B) = 55 i.e. domestic stocks that performs below average
n(B) = 505 i.e. all domestic stocks
The probability is then calculated as:
[tex]P(A\ |\ B) = \frac{n(A\ n\ B)}{n(B)}[/tex]
This gives
[tex]P(A\ |\ B) = \frac{55}{505}[/tex]
[tex]P(A\ |\ B) = 0.109[/tex]
Hence, the probability P(the stock performs below average|domestic) is 0.109

Answer:
n = - 6Step-by-step explanation:
Given is the system of linear equations:
nx + 3y = 612x - 6y = 0Convert both equations into slope intercept form:
nx + 3y = 6 ⇒ 3y = - nx + 6 ⇒ y = - 1/3nx + 212x - 6y = 0 ⇒ 6y = 12x ⇒ y = 2xThe system has no solution if lines have equal slopes with different y-intercepts:

f(-2)=
f(0)=
f(5)=
Answer:
[tex]f(x) = x + 6 \\ f( - 2) = - 2 + 6 = 4 \\ f(0) = 0 + 6 = 6 \\ f(5) = 5 + 6 = 11[/tex]
Answer:
The answer is 4, 6 and 11 when x = (-2), 0 and 5 respectively
Step-by-step explanation:
Given; we are given an equation x + 6When, x = (-2), 0 and 5Now,
f(x) = x + 6
For x = (-2)
f(-2) = -2 + 6
f(-2) = 4
For x = 0
f(0) = 0 + 6
f(0) = 6
For x = 5
f(5) = 5 + 6
f(5) = 11
Thus, The answer is 4, 6 and 11 when x = (-2), 0 and 5 respectively

Step-by-step explanation:
Y is a directly proportional to x and y= 15 when x =6. Find x when y =40.
Answer:
x = 16 when y = 40
Step-by-step explanation:
as y is directly proportional to x:
y = x
y = k x .........k is here constant.
15 = k * 6
k = 15/6
k = 5/2
Here constant, k is (5/2)
So when y = 40
y = k x
40 = (5/2)x
x = 40(2/5)
x = 16

What is an isosceles right-angled triangle?An isosceles right angled triangle has two equal sides, and those two equal sides make 90 degrees (right angle) internally in the triangle.
Therefore, an isosceles right angled triangle will be a right angle triangle with both legs of the triangle measuring exactly the same.
The given triangle is an isosceles right angle triangle. Let the length of the legs of the right-angle triangle be represented by x. Therefore, using the Pythagoras theorem we can write the length as,
x² + x² = 14²
2x² = 14²
√2 · x = 14
x = 14/(√2)
Now, the area of the isosceles right-angle triangle can be written as,
Area of the triangular field
= (1/2) × Height of the triangle × base of the triangle
= (1/2) × 14/(√2) × 14/(√2)
= (14 × 14)/(2 ×√2 × √2)
= 196/4
= 49 ft²
Hence, the amount of soil that is needed to cover the garden with a layer of soil is 49 ft².

Adam had $27 to spend on 3 beakers for his science class. After buying them, Adam had $6 left. How much did each of the beakers cost?
Answer: $7
Step-by-step explanation: So $27 -$6= $21.Then you Divide by 3 and you will get $7 for each beaker.
Answer:
$7
Step-by-step explanation:
In order to find the total cost of the 3 beakers, take away $6 from the total amount Adam has.
$27 - $6 = $21
$21 is the amount needed for 3 beakers, hence to find 1 beaker, you just have to divide $21 by 3.
$21 ÷ 3 = $7
Therefore, each beaker costs $7.

What is the area of this polygon?
Answer:
50
Step-by-step explanation:
I think it's 50 because the length is 10 units long And the width is 5 units long and when you do area, you multiply the width times length.
Answer:
51 [tex]units^{2}[/tex]
Step-by-step explanation:
You can split the polygon into two shapes, a triangle and a square. First, let's find the area of the square. The length of this figure is 7 and the height is 6. So, all we do is multiply 7 times 6 and get the area of the square to be 42.
Next, let's find the area of the triangle. The formula to find the area of a triangle is: [tex]\frac{1}{2} bh[/tex]. The base (or length) of this figure is going to be 6, while the height of this figure is going to be 3. We can then plug in these numbers into the formula: [tex]\frac{1}{2}(6)(3)[/tex]. This gives us the answer of 9.
We then can add these numbers up and get the area of the polygon to be 51 squared units.

Joni has two cats in the yard, Stephen and Graham. If both animals gained 20 pounds, Stephen would be 25% heavier than Graham. For what it’s worth, if they both lost 20 pounds, Stephen would be 50% heavier than Graham. How much does each animal weigh?
Answer:
Stephen weighs 80 lbs
Graham weighs 60 lbs
Step-by-step explanation:
Let Stephen the cat = S
Let Graham the cat = G
25% heavier = 125% = 125/100 = 1.25
50% heavier = 150% = 150/100 = 1.5
If both animals gained 20 lbs, S would be 25% heavier than G:
S + 20 = 1.25(G + 20)
⇒ S = 1.25(G + 20) - 20
⇒ S = 1.25G + 5
If both animals lost 20 lbs, S would be 50% heavier than G:
S - 20 = 1.5(G - 20)
⇒ S = 1.5(G - 20) + 20
⇒ S = 1.5G - 10
Equate both equations for S, and solve for G:
S = S
⇒ 1.25G + 5 = 1.5G - 10
⇒ -0.25G = -15
⇒ G = 60
Substitute found value for G into one of the equations for S and solve for S:
S = 1.5G - 10
⇒ S = 1.5 x 60 - 10
⇒ S = 90 - 10
⇒ S = 80
Stephen weighs 80 lbs
Graham weighs 60 lbs

On November 1, 20X1, Gerakos Corporation sold software and a six-month technical support contract to a customer for $80,000. Gerakos sells technical support for $30,000. It does not sell the software separately. Gerakos uses the residual method to allocate the transaction price.
The revenue that Gerakos will recognize in 2019 and 2020 based on the residual method is as follow:
2019 2020
Software $50,000 $0
Technical support $10,000 $20,000 ($30,000 x 4/6)
Total revenue $60,000 $20,000
What is the residual method of revenue recognition?Under the residual method, the price of the technical support of $30,000 is apportioned between 2019 and 2020. Since the contract for technical support is for a six-month period, $10,000 ($30,000 x 2/6) will be recognized in 2019 while $20,000 ($30,000 x 4/6) is deferred to 2020. However, the revenue for the sale of the software is recognized only in 2019.
Question Requirement:What amount of revenue does Gerakos recognize in 2019 and in 2020?
Thus, in 2019, Gerakos will recognize a revenue of $60,000 and $20,000 in 2020.
