Answer: y=x+4
Step-by-step explanation:
if you need to find the y
we divide the equation by 4
x-y=-4
add y on both sides
y=x+4

Answer:
no, I believe the correct answer would be D. (-4, 4)
Answer:
(-4, 4)
Step-by-step explanation:
Even though I don't see it explained anywhere, it seems that what looks like the coordinates of two points is really the coordinates of the first point and the translation.
That means that (-9, 6) is the original point.
(5, -2) is the translation which is a translation of 5 in x and a translation of -2 in y.
Start with (-9, 6)
Apply the translation to x and y (-9 + 5, 6 + (-2))
You get (-4, 4)
Answer: (-4, 4)

Show that a vector
[tex]u = x _{1}i + y_{1}j + z_{1}k[/tex]
with direction cosines (cos α, cos β, cos gamma) can be written as
[tex]u = |u| ( \cos \alpha i + \cos\beta j + \cos \gamma k)[/tex]
Answer:
u = |u|(cos∝+cosβ+cosγ)
Step-by-step explanation:
Explanation
Proof:-
Given a vector u = x₁ i + y₁j +z₁k
let O X, OY, O Z be the positive co-ordinate axes
P(x₁,y₁,z₁) be any point in the space
Let OP makes angles α,β,γ with co-ordinate axes OX , OY ,OZ .
The angle α,β,γ are known as direction angles and cosine of the angle
l =cosα , m= cosβ , n=cosγ
The perpendicular PA,PB,PC are drawn co-ordinate axes OX,OY,OZ respecctively
InΔOAP , ∠A =90° , cos∝ =[tex]\frac{x}{r}[/tex]
x₁ = rcos∝
InΔOBP , ∠B =90° , cosβ =[tex]\frac{y}{r}[/tex]
y₁ = rcosβ
InΔOCP , ∠C =90° , cosγ =[tex]\frac{z}{r}[/tex]
z₁ = rcosγ
Given u = x₁ i + y₁j +z₁k
|u| = [tex]\sqrt{(x_{1})^{2} +(x_{2} )^{2} +(x_{3} )^{2} }[/tex]
Therefore u = x₁ i + y₁j +z₁k
u = |u|(cos∝+cosβ+cosγ)

A suppliers sold a machine levying 13% vat on rupees 320000 to a retailer. the retailer spent rupees 10000 for transportation and rupees 5000 for the local tax if the retailer sold it at a profit of rupees 15000 to a customer how much did the customer pay for the machine with 13% vat?
Answer:
395,500
Step-by-step explanation:
The computation is shown below:
Supplier to retailer = 320,000
Vat tax = 13%
Retailer spent for transportation = 10,000
local tax = 5,000
Profit = 15,000
Now based on the above information
the customer would pay the amount with 13% vat is
= (320,000 + 10,000 + 5,000 + 15,000) + 13% of total
= 350,000 + 13% of 350,000
= 350,000 + 45,500
= 395,500

Answer:
they were right
Step-by-step explanation:
The first equation represents the number of questions on the test. So, the second equation represents how much the questions are worth.
There are x of the 2-point questions, which have a total value of 2x points.
There are y of the 4-point questions, which have a total value of 4y points.
The test has an overall value of 150 points, so the second equation is 2x + 4y = 150.

Daniel plays two games in the casino. The first game he believes he has 60% chance to win. If he wins the first game, he will win the second game with 35% chance, if he loses the first game, he will win the second game with 65% chance. The winning prices for the first and second game are $1 and $2 respectively. a. If he wins the second game, what is the probability that he lost the first game
Answer:
0.5532
Step-by-step explanation:
We have these events
WF = Wins the first game
LF = lose the first game
WS = Wins the second game
LS = lose the second game
Then
Prob(WF) = 0.6
Prob(LF) = 0.4
Prob(WS|WF) = 0.35
Prob(WS|LF) = 0.65
1. If he wins the second game, the probability that he lost the first =
P(Lf|WS)
= 0.4x0.65/0.4x0.65+0.6x0.35
= 0.21/0.47
= 0.5532
0.5532 is the probability that he lost the first game given that he wins the second

Answer:
Option A Domain: all real numbers between –2.5 and 2.5 range: all real numbers greater than or equal to –5
Step-by-step explanation:
Domain corresponds to the values of x and Range corresponds to the value of y. If sketch the graph on an online calculator we can see that the domain lies between -2.5 and 2.5 for x and the range corresponds to y as in this case
range ≥ -5.

Step-by-step explanation:
A farmer notices that there is a linear relationship between the number of bean stalks, n, she plants and the yield, Y. When she plants 2 stalks, each plant yields 70 ounces of beans. When she plants 8 stalks, each plant yields 160 ounces of beans.
Which of these equations correctly represents this situation?
Select the correct answer below:
Y(n)=19n+32
Y(n)=11n+72
Y(n)=11n+48
Y(n)=19n+8
Y(n)=15n+30
Y(n)=15n+40
Answer:
Y(n)=15n+40
Step-by-step explanation:
Lets represent the number of bean stalks she plant by n and
the yield by Y.
It says in the question that when she plants 2 stalks, each plant yields 70 ounces of beans. When she plants 8 stalks, each plant yields 160 ounces of beans.
Which means 2 stalks correspond to 70 ounces and 8 stalks corresponds to 160 ounces we could write the data Mathematically like:
(2 , 70) and (8 , 160) are our coordinates where the x-axis would be n the number of beans stalks planted and y-axis would be Y the yield in ounces.
So we have two coordinates and to find the linear relationship we must find out the slope/gradient(m) of the linear function by the formula of slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{160-70}{8-2} \\\\m=\frac{90}{6} \\\\m=15[/tex]
so we plug in one of the coordinates and our slope in the point-slope formula :
[tex]y-y_1=m(x-x_1)[/tex]
where,
[tex](x_1,y_1)\ represent\ the\ coordinate\ (2,70)[/tex]
so plugging in the coordinate and the value of m we get:
[tex]y-y_1=m(x-x_1)\\y-70=15(x-2)\\y-70=15x-30\\y=15x-30+70\\y=15x+40\\[/tex]
so our the answer is the last option
Y(n)=15n+40
here x corresponds to n and y corresponds to Y(n)
PLEASE HELP ME!!!
On a road trip a family drives 350 miles per day how many days D must they travel to reach the distance of at least 1400. Solve the inequality what does the solution represent in this situation?
(Just in case you wanted to see the question I put a picture)
Answer:
[tex]350 * D \geq 1400[/tex]
[tex]D\ge 4[/tex]
This means that the family must travel for at least 4 days.
Step-by-step explanation:
Given
[tex]Rate = 350\ miles\ daily[/tex]
[tex]Distance = 1400\ miles\ (atleast)[/tex]
Required
Determine and solve the inequality
The number of days is represented with D
So:
On any D number of days, the family would have covered a distance of 350 * D miles
If the total distance is at least 1400, then the inequality is:
[tex]350 * D \geq 1400[/tex]
[The term "At least" is used to represent greater than or equal to]
[tex]350 * D \geq 1400[/tex]
Divide through by 350
[tex]\frac{350 * D}{350} \ge \frac{1400}{350}[/tex]
[tex]D \ge \frac{1400}{350}[/tex]
[tex]D\ge 4[/tex]
This means that the family must travel for at least 4 days.

quadrilateral ABCD is dilated by a scale factor of 2 centered around (2,2). Which statement is true about the dilation?
Answer:
The vertices of the image will have the coordinates
A(-5, 1) → A'(2x-2, 2y-2) → A'(-12, 0)
B(-4, 3) → B'(2x-2, 2y-2) → B'(-10, 4)
C(1, 2) → C'(2x-2, 2y-2) → C'(0, 2)
D(-3, 0) → D'(2x-2, 2y-2) → D'(-8, -2)
Step-by-step explanation:
Note: You missed to mention the vertices of a quadrilateral ABCD. So, I am assuming the following vertices. It would anyways clear your concept.
Let us suppose
A(-5, 1)B(-4, 3)C(1, 2)D(-3, 0)We know that the rule of the dilation with the center of dilation at (2,2) by a scale factor of 2 is:
(x, y) → (2x-2, 2y-2)Therefore, the vertices of the image will have the coordinates
A(-5, 1) → A'(2x-2, 2y-2) → A'(-12, 0)
B(-4, 3) → B'(2x-2, 2y-2) → B'(-10, 4)
C(1, 2) → C'(2x-2, 2y-2) → C'(0, 2)
D(-3, 0) → D'(2x-2, 2y-2) → D'(-8, -2)
