Answer:
[tex]y=2x-3[/tex]
Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to [tex]2x-y-9=0[/tex]
[tex]5x+y+4=0[/tex]
[tex]y= -4-5x[/tex]
substituting the value of y in [tex]2x+3y=1[/tex]:
[tex]2x +3(-4-5x)=1\\\\2x-12-15x-1=0\\-13x=13x\\x= \frac{13}{-13}= -1[/tex]
substituting x=-1 in y= -4-5x:
[tex]y= 1[/tex] (upon solving, you should get this)
[tex](x,y)= (-1,1)[/tex]
2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)
[tex]2x-y-9=0\\2x-9=y\\y= 2x-9[/tex]
[tex]y= mx+c\\[/tex]
-1= 2 x 1 +c
-3=c
y= 2x-31/3x 6,000

Kelsie sold digital cameras on her website. She bought the cameras for $65 each and included a 60% markup to get the selling price. To the nearest dollar, what was the selling price for one camera? Please show work.
Answer:
$104
Step-by-step explanation:
Find 60% of 65 then add it to 65:
0.6 * 65 = 39
Now add it to 65:
39 + 65 = 104
Therefore she's selling cameras for $104 each.

Step-by-step explanation:
how do you get -11.9 from -6.7+(-5.2)
and explain in words how
If you just type that exact equation into a calculator it gives you the same answer as well
Answer:
You get -11.9 from -6.7+(-5.2) because you are adding 2 negative numbers. Just forget the negative signs are there when your adding negatives. 6.7 + 5.2 = 11.9 and then just add the negative in front and that's how you get your answer -11.9

Carol is mixing pink paint. The ratio of red to white paint is 2:1. If carol uses 6 parts red paint. How much white paint does she need?
Answer:
3 parts
Step-by-step explanation:
This is just ratios. We know that red paint:white paint is equal to 2:1. Therefore we just have to substitute the values in.
Red paint = 6, so
6: White paint (=1)
Meaning that all we have to do is divide 6 by 2 (to find the value of one part), giving us 3 parts.

is the square root of 2/5 an irrational number?
Answer: no, it is rational
Answer and Step-by-step explanation:
No, the square root of [tex]\frac{2}{5}[/tex] is NOT IRRATIONAL. That means it IS rational.
Since [tex]\frac{2}{5}[/tex] is a rational, positive number, squaring the number will still make it rational.
The square root of [tex]\frac{2}{5}[/tex] is [tex]\frac{\sqrt{10} }{5} , or///0.632455532[/tex]

Beatriz takes a simple random sample of 350350350 orders from the more than 500050005000 total orders to her store and finds that 12\, percent of the sampled orders were returned. Assuming that it is really 9\%9%9, percent of all orders to her store which were returned, what is the approximate probability that more than 12\, percent of the sampled orders would have been returned
If Beatriz takes a simple random sample of 350 orders from the more than 5000 total to her store and finds. The probability that more than 12 percent of the sampled orders would have been returned is 0.02.
How to find the probability?Mean = n * p
Mean = 350 * 0.09
Mean= 31.5
Standard deviation = √ p * (1 - p)/n
Standard deviation = √ 0.09 * 0.91/350
Standard deviation = 0.01529
Using the normal distribution table
p>0.12
P(p>0.12) =0.02
Therefore the probability that more than 12 percent of the sampled orders would have been returned is 0.02.

Michael is buying new shirts and pants for school. He bought shirts for $38 each and pants for $38 each. He purchased nine items and spent a total of $222. How many shirts did he buy?
Answer:
No possible solution
Step-by-step explanation:
Let:
Shirt = x
Pant = y
x + y = 9 - - - - - - - - - (1)
38x + 38y = 222 - - - (2)
From (1):
y = 9 - x
Put y = 9 - x in (2)
38x + 38(9 - x) = 222
38x + 342 - 38x = 222
Based on the Given parameters, we can conclude that the equation does not have a possible solution.
