DETERMINE WHICH OF THE LINES ARE PARALLEL OR PERPENDICULAR thx sm
Answer:
Parallel: a and b
Perpendicular: none
Step-by-step explanation:
You are given the coordinates of each line.
To check if they are parallel or perpendicular, need to find slope.
In this case we can use :
m = (y2 - y1) / (x2 - x1)
So for line a:
(1,5) and (-2, -4)
slope = (-4 - 5) / (-2 - 1)
slope = -9/-3
slope = 3
Line b:
(3, 2) and (1, -4)
slope = (-4 - 2)/(1 - 3)
slope = -6/-2
slope = 3
Line C:
(6, 1) and (-4, 2)
slope = ( 2 - 1) / ( -4 -6)
Slope = 1/ -10
slope = - 1/10
Line A and B are parallel because their slopes are the same.
To check if they are perpendicular, we need to know if their slopes are reciprocals.
Here none of them are perpendicular to each other

Luis has 3 pounds of ground turkey to make turkey burgers. He uses 3/8 pound per burger to make 6 burgers. How many 1/4 pound burgers can Luis make with the remaining turkey?
Answer: he can make 3 1/4 pound burgers.
Step-by-step explanation: we know that he starts with 3 lbs of burger meat, and uses some of the meat to make 6 burgers that each weigh 3/8 lbs. If you take the 3/8 lbs and multiply by 6 burgers, you get 18/8, which is how much has been used so far. If you subtract 18/8 from the 3 lbs that Luis has originally started with, you get 6/8 lbs, which is how much he has after his first 6 burgers. Then you can take the 1/4 and see how many times it fits into 6/8 (1/4=2/8, 6/8 divided by 2/8 = 3 burgers that each weigh 1/4 lbs)
calculate the state income tax owed on a $50,000 per year salary (answer is not 2500)
The total tax paid is $2,300 on the yearly salary of $50,000
What tax rate applies to the first $10,000 of salary?
The first $10,000 of the salary would be charged to tax at 3% whereas the next threshold beyond $10,000 up until $50,000, in other words, the difference between the first $10,000 and $50,000, which is $40,000 is taxed at 5%.
The tax on the first $10,000 is computed as shown below:
tax on the first $10,000=$10000*3%
tax on the first $10,000=$300
The tax on the remaining $40,000 is 5% of the amount
The tax on the remaining $40,000=5%*$40,000
The tax on the remaining $40,000=$2,000
In other words, the total tax paid on the $50,000 annual salary is the sum of $300 and the $2000
total tax paid=$300+$2,000
total tax paid=$2,300

What is the equation of the line with a slope of 4 and passes through the point (1, -4)?
Answer:
y=4x-8
Step-by-step explanation:
m=4 (1,-4)
-4=4(1) + c
-4=4+c
-4-4=c
-8=c
y=4x-8
Answer: y = 4x - 8
Step-by-step explanation:
The best way to go about this is to first put the information you know into point-slope form, which is:
[tex]y-y_{1} =m(x-x_{1})[/tex]
[tex]y_{1}[/tex] and [tex]x_{1}[/tex] represent the values of our point (1, -4), so:
[tex]y_{1}=-4[/tex], and [tex]x_{1}=1[/tex].
[tex]m[/tex] represents our slope of 4, so:
[tex]m=4[/tex]
From this, we can plug in our values:
[tex]y-(-4)=4(x-1)[/tex]
A little simplification and distrobution takes us to this:
[tex]y+4=4x-4[/tex]
Then simply subract 4 from both sides to get this:
[tex]y=4x-8[/tex]
An easier way to reason this is to visualize the line in your head and figuring out what the y-intercept is so you can go strait into the [tex]y=mx+b[/tex] form where b is the y-intercept.
The wallaby is essentially a small kangaroo that is native to Australia. To monitor the wallaby population, scientists catch 88 and tag them. A month later, they capture 600 wallabies and notice that 44 have tags. To the nearest viole number, what is the best estimate for the TOTAL wallaby population using ratios?
The best estimate for the total wallaby population is 1200.
Since to monitor the wallaby population, scientists catched 88 and tag them, already a month later, they captured 600 wallabies and noticed that 44 had tags, to determine what is the best estimate for the total wallaby population using ratios, the following calculation must be done:
44 = 600 88 = X 88 x 600/44 = X 1200 = X
Therefore, the best estimate for the total wallaby population is 1200.

if a baseball team has lost 50 matches out of the 120 matches played in total, find out their winning percentage?
The percentage is the indicating hundredth thus the percentage of winning is 58.33%.
What is the percentage?The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
As per the given,
Total matches = 120
Number of lost matches = 50
Number of winning match = 120 - 50 = 70
Winning percentage = (70/120) x 100 = 58.33%
Hence "The percentage is the indicating hundredth thus the percentage of winning is 58.33%".

EI = IG = FI = IH
IGF = IFG = IEH = IHE
therefore, since EI = FI
2x + 8 = 6x - 20
28 = 4x
x = 7
now,
EG = EI + IG = 2×EI = 2×(2×7 + 8) = 2×22 = 44
IFE is a complementary angle to IFG (together they have 90°).
and because IFG = IGF = 30°
IFE = 90 - 30 = 60°

A rental car company charges $51 per day to rent a car and $0.14 for every mile driven. Damian wants to rent a car, knowing that: He plans to drive 250 miles. He has at most $290 to spend. Use the drop-down menu below to write an inequality representing dd, the total number of days Damian can rent the car while staying within his budget.
Answer: Damian can rent the car for 5 days.
Step-by-step explanation:
Money for 250 miles driven - 0.14*250= 35
Day 1 - 35+51= 86
