Answer:
The perpendicular line is:
y = 1/3 x + 2/3
Step-by-step explanation:
The given equation can be reduced to its slope-intercept form as shown below:
3x + 9y = 8y - 2
subtract 8 y from both sides
3 x + y = -2
subtract 3 x from both sides
y = - 3 x -2
therefore we know that the slope of this line is -3, and then, a perpendicular line to it must have slope given by the "opposite of the reciprocal" of this slope. That is, the slope of any perpendicular line to this one must be: 1/3
We use this slope to find the equation of the line passing through the point (13. 5)
y = 1/3 x + b
passing through (13, 5) means:
5 = 1/3 (13) + b
therefore, we can find b from the above equation
b = 5 - 13/3 = 15/3 - 13/3 = 2/3
Then the equation of this perpendicular line is:
y = 1/3 x + 2/3

Help me solve this problem and explain to me please
A manufacturer with exclusive rights to a sophisticated new industrial machine is planning to sell a limited number of the machines to both foreign and domestic firms. It is estimated that if the manufacturer supplies machines to the domestic market and machines to the foreign market, the machines will sell for −+ thousand dollars apiece domestically, and for +− thousand dollars apiece abroad. If the manufacturer can produce the machines at the cost of $ apiece, how many should be supplied to each market to generate the largest possible profit?
Answer:
Supply all machines to the which ever market provides the highest price.

Choose all of the statements that are true about AABC.
Answer:
Step-by-step explanation:
sin(62°) = 25/BA
BA = 25/sin(62°) ≈ 28.3
Angle BAC = 180°-90°-62° = 28°
BC = √((BA)^2-(AC)^2) = 13.3
cosC = 0
Answer:
A and D are correctStep-by-step explanation:
Given ΔABC
∠C = 90°∠B = 62°AC = 25The options:
A. 25/BA = sin 62° ⇒ BA = 25/sin 62° = 28.3 ≈ 28
CorrectB. ∠BAC = 90° - 62°= 28° ≠ 48°
IncorrectC. 25/BC = tan 62° ⇒ BC = 25/tan 62° = 13.29 ≠ 18
IncorrectD. cos(∠ACB) = 0 ⇒ cos 90° = 0
Correct........................

Which equation has the solution X = 2?
Answer:
B
Step-by-step explanation:
B: 3x + 2 =8
The first step to solving for X is isolating the variable, so we subtract 2 from both sides!
3x=6
Now we divide both sides by three to isolate the X:
X=2

7:8
Answer:
7 : 8
Step-by-step explanation:
Total number of adults in the survey = 150
Number of women = 80
Number of men = 150 - 80
= 70
Ratio of men : women = 70 : 80
= 70 /80
= 7 / 8
= 7 : 8

Of the 600 sixth graders at Melville Middle School, 80% want more field trips. How many students want more field trips? Show your work. How many students is 10%
Answer:
480 students want more field trips.
60 students is 10%.
Step-by-step explanation:
There are 600 students, and 80% want more field trips.
80% of 600 is 0.8*600 = 8*60 = 480 students.
480 students want more field trips.
How many students is 10%?
10% of 600 is 0.1*600 = 60*1 = 60
60 students is 10%.
