Answer:
y = -3x - 4
Step-by-step explanation:
[tex]\frac{8-y}{-4-x} = \frac{-3}{1}[/tex]
[tex]y = 11\\x = -5[/tex]
(-5,111)
y = -3x + b
8 = -3(-4) + b
8 = 12 + b
b = -4
y = -3x - 4

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman B a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman C a proportional relationship? Use complete sentences to explain your reasoning.
Answer:
See below
Step-by-step explanation:
Proportional relationship formula:y = kxAs per given we have:
Salesman A
p(s) = 65s (p = $1300 maximum)This is a proportional relationship, $65 per each sale. But this is restricted to 20 sales.Answer is yes (ignoring the restriction)Salesman B
p(s) = 40s + 300This is a linear but not proportional relationshipAnswer is noSalesman C
p(s) = 900There is no relationship between sales number and weekly earning as it is a fixed salaryAnswer is no1. f(x) = 2x + 4 when x = 5
Answer:
f(5)=14
Step-by-step explanation:
f(5)=2(5)+4
f(5)=10+4
f(5)=14
Answer:
14
Step-by-step explanation:
Ignore the f(x) for now.
x is 5, so we plug it in to get 2*5+4. Using PEMDAS, you multiply 2 and 5 to get 10 and add 4 to get 14.
2x+-2y=14
x+4y=13
Elimination Method to Solve Linear Equations
Answer:
(41/5, 6/5)
Step-by-step explanation:
2x+-2y=14
x+4y=13
You can multiply the first equation by 2 so you can eliminate the y:
2(2x+-2y=14)
4x+-4y=28
Then you can set up both equations to be added together:
4x+-4y=28
+ x+4y=13
5x=41
x=41/5
Then you can substitute 41/5 for x in the original equation:
x+4y=13
41/5+4y=13
5(41/5+4y)=5(13)
41+20y=65
20y=24
y=24/20
y=6/5
Check:
2x+-2y=14
2(41/5)+-2(6/5)=14
82/5+-12/5=14
70/5=14
14=14
Im not sure how to find the missing angle
Answer:
Step-by-step explanation:
the question is asking for the length of the side labeled x
use Pythagoras' theorem to find that side
where c = x because c represents the hypotenuse in the theorem and x is on the hypotenuse in this problem
c = [tex]\sqrt{a^{2} + b^{2} }[/tex]
sooo plug in a = 14 and b = 10
c = [tex]\sqrt{14^{2} + 10^{2} }[/tex]
c = [tex]\sqrt{196+100}[/tex]
c = [tex]\sqrt{296}[/tex]
c= 17.20465..... ( that's the approx. length of side x in the problem )
since this is a right triangle we could use trigonometry to find the two angles use SOH CAH TOA to remember how those functions fit on the triangle.
Sin(Ф)=Opp/Hyp Cos(Ф)=Adj/Hyp Tan(Ф)=Opp/Adj
since we know the Hyp (hypotenuse) and the side adjacent will be the side with the 10 soooo...
Cos(Ф)=10/17.20465
Ф = arcCos(10/17.20465)
Ф = 54.4623° is the angle on the side with 10
the side with 14 then has an angle of 35.5376°

Ahmed buys a house for 179500 a year later he sells the house for 190270 calculate the percentage profit
Step-by-step explanation:
For percentage profit questions, use this formula:
Percentage 'change' = 'change' / original x 100
(where 'change' is the difference between the 2 values)
Now subsitute the values:
Percentage Change = 10770 / 179500 × 100

Question: How many solutions: x + 2y = 6 and 2x − 3y = 26
Answers/Answers to choose from:
One-Solution
Infinitely Many Solutions
Or No Solution
(Basically does the question have only one solution, infinitely many solutions, or does it have no solution) Please don't guess
Answer:
one-solution
Step-by-step explanation:
(x + 2y = 6)2
2x - 3y = 26
2x + 4y = 12
2x - 3y = 26
7y = -14
y = -2
x + 2(-2) = 6
x + -4 = 6
x = 10
Answer:
One-SolutionStep-by-step explanation:
It is two lines, if they intersect there is one solution, if parallel- no solution, if same lines- infinitely many solutions
Lets put them in slope-intercept form and compare:
x + 2y = 6 ⇒ 2y = -x + 6 ⇒ y = -1/2x + 32x - 3y = 26 ⇒ 3y = 2x - 26 ⇒ y = 2/3x - 26/3As we see the lines have different slopes, so they intersect which means one solution only.

15) Evaluate the following expression for x=0.2 and y=3.4: x(y2 - 4)
Answer:
x(y² - 4) = 1.512
Step-by-step explanation:
We need to evaluate the following expression for x = 0.2 and y = 3.4 :
x(y² - 4)
Put the values of x and y.
x(y² - 4) = (0.2)((3.4)² - 4)
= (0.2)((3.4)² - 4)
= 0.2×7.56
= 1.512
So, the value of the above expression is 1.512

Need help on 12...have to find the area..teacher said to use pythagreoum(how ever u spell it) theorem
Answer:
58[tex]\sqrt{65}[/tex]
Step-by-step explanation:
you can find the height of this trapezoid by using the pythagorean theorem where the hypotenuse is 18 and one leg is 8 (33-25)
let x = height
[tex]8^{2}[/tex] + [tex]x^{2}[/tex] = [tex]18^{2}[/tex]
[tex]x^{2}[/tex] = 324 - 64
[tex]x^{2}[/tex] = 260 therefore, x = [tex]\sqrt{260}[/tex]
[tex]\sqrt{260}[/tex] = [tex]\sqrt{4}[/tex]· [tex]\sqrt{65}[/tex] or 2[tex]\sqrt{65}[/tex]
A = [tex]\frac{1}{2}[/tex]h x (sum of the bases)
bases are 25 and 33
A = (2[tex]\sqrt{65}[/tex]) ÷ 2)58
The sum of three consecutive even numbers is 450. What is the 3rd number?
Step-by-step explanation:
Which means that the first number is 149, the second number is 149 + 1 and the third number is 149 + 2. Therefore, three consecutive integers that add up to 450 are 149, 150, and 151. We know our answer is correct because 149 + 150 + 151 equals 450 as displayed above.
PLEASE MARK ME AS BRAINLIEST ANSWER
HOPE IT HELPS YOU
The three consecutive integers that add up to 450 are 149, 150, and 151.
What are the consecutive numbers?The consecutive numbers are those numbers that follow each other continuously in the order from smallest to largest numbers.
Given that the sum of three consecutive even numbers is 450
We need to find the 3rd number of the integers.
Now assume the 3 consecutive integers are x, (x+1) and (x+2)
Therefore, x+(x+1)+(x+2)= 450
Combine the like terms;
3x+3= 450
X=149
Thus the second number is 149 + 1 and the third number is 149 + 2.
Hence, the 3rd number of the integers would be 151.
