Answer:
y = (3/2)x - 8 slope-intercept form
3x - 2y = 16 standard form
Step-by-step explanation:
Use the point-slope form of a line to do this problem.
[tex]y - y_{1} = m(x - x_{1} )\\[/tex]
In your case [tex](x_{1} , y_{1} ) = (8, 4)[/tex]
So. y - 4 = 3/2 ( x - 8)
multiply thru by 2
2y - 8 = 3(x - 8)
2y - 8 = 3x - 24
2y = 3x - 16
y = (3/2)x - 8 slope-intercept form
3x - 2y = 16 standard form

Answer:
3x+2y
Step-by-step explanation:
Find the rectangles attached
Area of a rectangle = Length * Width
A = A1+A2
given
A = 30cm²
A1 = 3 * x
A1 = 3x
A2 = 2*y
A2 = 2y
Substitute
30 = 3x+2y
Hence the required equation is 3x+2y = 30
Answer: 3x + 2y = 30
Step-by-step explanation:
A = L x W
The sum of the rectangle is 30.
One angle is 3 and x, the other one is 2 and y.
Multiply 3 with x = 3x.
Multiply 2 with y = 2y
Then create your equation plugging in 30 as the answer to 3x + 2y

what is this(9 + 4) × (8 -7)
Answer:
13
Step-by-step explanation:
To solve this you have to add 9 and 4 first so you get 13. Next, you have to subtract 8 from 7 so you get 1. Now all you have to do is multiply 13 and 1 so you get 13 as your answer.
9 + 4 = 13
8 - 7 = 1
13 × 1 = 13
I hope this helps you :D
Answer:

Inga and Aileen are measuring the temperature of frozen hydrogen. Inga is using a thermometer that has increments of 0.25∘F, and she gets a measurement of 3.25∘F. Aileen is using a thermometer that has increments of 0.125∘F, and she gets a measurement of 3.375∘F.
Which thermometer has less uncertainty?
1. Aileen's thermometer, because it has smaller increments.
2. Neither, because the uncertainty in both thermometers is the same.
3. Inga's thermometer, because 3.25∘F is less than 3.375∘F.
4. Neither, because Inga and Aileen had different measurements.
Answer: AILEEN’S THERMOMETER, BECAUSE IT HAS SMALLER INCREMENTS
Step-by-step explanation:
I did the test and the attachment below is a screenshot of my test and I got 100%
Aileen's thermometer has less uncertainty because it has smaller increments. Option A is correct.
Given that,
Inga and Aileen are measuring the temperature of frozen hydrogen. Inga is using a thermometer that has increments of 0.25∘F, and she gets a measurement of 3.25∘F. Aileen is using a thermometer that has increments of 0.125∘F, and she gets a measurement of 3.375∘F.
All over the world, most things are in use as of common quantity, so people all over the world agree that they have to follow a common system of measurement and that the common system of measurement is called standard measurement.
Here,
Aileen's thermometer has a smaller increment than Inga's thermometer,
Because of the smaller increments, it has more chances to give precise measurements and less uncertainty.
Thus, Aileen's thermometer has less uncertainty because it has smaller increments. Option A is correct.

A camera has a listed price of $819.99 before tax. If the sales tax rate is 6.75%, find the total cost of the camera with
sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
The answer is $875.34
Step-by-step explanation:
I got this answer from first finding what 6.75% of 819.99
819.99 * 6,75% = 55.349325
Next I rounded it.
55.349325 = 55.35
Lastly, I added 819.99 plus 55.35
819.99 + 55.35 = 875.34

After a 40% discount, the cost of a sofa is $471.00. What was the original cost of the sofa? NEED HELP ASAP
Answer: $659.40
Step-by-step explanation: You start with 471.00 X 0.4 which equals $188.40. So then you add $471.00 and $188.40 and you get $659.40!
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
80% = $471
100% = $588.75
The original cost of the sofa is $588.75
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Original cost in percentage = 100% ____(1)
Cost after 40% discount = $471
This can be written as,
80% = $471 _____(2)
From (1) and (2) we get,
80% = 471
Multiply 100/80 on both sides,
100/80 x 80% = 100/80 x 471
100% = $588.75
Thus,
80% = $471
100% = $588.75
The original cost of the sofa is $588.75
