2y=-5/6x+5
Write in standard form
Answers
Answer:
5x + 12y = 30
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
2y = - [tex]\frac{5}{6}[/tex] x + 5 ( multiply through by 6 to clear the fraction )
12y = - 5x + 30 ( add 5x to both sides )
5x + 12y = 30 ← in standard form
A store is selling all toaster ovens at 15% off. Write an equation in the form y = kx to represent the sale price y in dollars of a toaster with an original cost of x dollars. Then find the amount Jill paid for a toaster with an original cost of $40.
Answers
Answer:
y=0.85x
Jill paid $34 for a toaster.
Step-by-step explanation:
Given that, x and y are the original cost and the sale price of the toaster oven after discount.
As there is 15% off on the original cost, so,
the discount amount = 15% of x
[tex]=\frac{15}{100}x[/tex]
=0.15x
Now, sale price = original cost - discount
[tex]\Rightarrow y = x-0.15x[/tex]
[tex]\Rightarrow y=0.85x[/tex]
This is the required equation in the form of y=kx, where k=0.85.
If the original cost of the toaster is $40.
Then the sale price,[tex]y=0.85\times 40=34.[/tex]
Hence, Jill paid $34 for a toaster.

Adam runs 4 miles in 20 minutes. How many miles does he run in 1 hour?
Answers
Answer: 12 miles
Step-by-step explanation:
Answer: Adam will run 12 miles in 1 hour.
Step-by-step explanation:
Ok, so we know 4 miles in 20 minutes, correct?
Multiply 20x2. You will get 40. Then, multiply 4x2. That is 8. So in 40 minutes he ran 8 miles. So if we multiply 20x3, we would get 60 minutes which is an hour. So we need to multiply 4 by 3–12.

Answer:
9) it's not, doesn't pass the vertical line test
12) it is because it does pass the vertical line test
Answer:
Number 9 is not a function number 12 is a function
Step-by-step explanation:
Number 9 is not a function because it did not pass the vertical line test which you have to hold a tool vertically and see if there are a line that touches it more than once if it does then it fails and it is not a function and if it only touches once then it passes and is a function but number 9 does touch more than one time so it is not a function
Number 12 is a function because it pass the vertical line test

Pete grabbed 18 mixed nuts 2/9 of which were almonds . Which equation shows how to determine the number of almonds pete grabbed. A. 18 divided by 2/9=81 B.18 times 2/9=4 C.2/9 divided by 18 = 1/81 D. 9/2 divided by 18= 4/1
Answers
Answer:
B.18 times 2/9=4
Step-by-step explanation:
Given that :
Number of mixed nuts grabbed by pete = 18
Fraction of almonds = 2/9
Number of almonds grabbed by pete :
Fraction grabbed × number of mixed fruits grabbed
2/9 × 18
= 36 / 9
= 4
Hence, Pete grabbed 4 almonds

3x

9y = -9
x + y = 1
Answers
Answer:
x=3, y= -2
Step-by-step explanation:
3x + 9y = -9
x + y = 1
Multiply the second equation by -3
-3x-3y = -3
Add this to the first equation to get rid of the x's
3x + 9y = -9
-3x -3 y = -3
------------------------
6y = -12
Divide by 6
6y/6 = -12/-6
y = -2
3x + 9y = -9
x + y = 1
Multiply the second equation by -9
-9x-9y = -9
Add this to the first equation to get rid of the y's
3x + 9y = -9
-9x -9 y = -9
------------------------
-6x = -18
Divide by -6
-6x/-6 = -18/-6
x = 3
Answer:
Here
the given equations are:-
3x + 9y = -9
or,3(x +3y)= -9
or,x+ 3y = -3 ................. (1)
x + y = 1 ................... (2)
Now , subtracting equation (2) from (1) , we ger:-
x + 3y = -3
x + y = 1
- - -
__________
0 + 2y = -2
or, y = -1
putting value of y in equation (2) , we get:-
x +(-2) = 1
or, x - 2 = 1
or x = 3
HENCE,
x = 3 and y = -1 are the values of x and y .

Diego has 90 songs on his playlist. How many songs are there for each genre? Type the answer in each box below. 1. 40% of the songs are rock, so there are rock songs. 2. 10% of the songs are country, so there are country songs. 3. 30% of the songs are hip-hop, so there are hip-hop songs. 4. The rest is electronica, so there are electronica songs.
Answers
Answer:
The answer is "Diego playlist has 36 rock songs, 9 country songs and 27 hip hop songs and 24 electronic songs".
Step-by-step explanation:
Total Songs on playlist = 90%
rock = 40%
country = 10%
hip hop = 30%
We need to find the number of songs in each genre.
rock = 40%
Therefore, rock album number[tex]= \frac{40}{100} \times 90 = 36 \ songs[/tex]
country = 10%
Thus number of country songs = [tex]\frac{10}{100} \times 90 = 9\ songs[/tex]
hip hop = 30%
So number of hip hop songs [tex]= \frac{30}{100} \times 90 = 27 songs[/tex]
Or resting was its genre of computing. Dividing number of lyrics in the digital genre and amount of songs in the rock genre in the country genre
Complete sum of songs of the hip hop genre.
We get equation framing; framing;
Amount of electronica songs = [tex]90-30-9-27=24 \ songs[/tex]

(7 points, A -REL.2.4) A packing company is doing an inventory of boxes. Their most popular box is displayed below. Use the formula for volume of a box, V = lwh. If the volume is 40f * t ^ 3 , find the value of x. Then find the length and width of the box. State any extraneous solutions.
Answers
Answer:
The extraneous solution is x = -5/6
Length = 4 ft
Width = 5 ft
Step-by-step explanation:
Length = 3x - 5 ft
Width = 2x - 1 ft
Height = 2 ft
Volume = 40 ft^3
Volume = length × width × height
40 = (3x - 5)(2x-1)(2)
40 = (6x^2 - 3x - 10x + 5)(2)
40 = 12x^2 - 6x - 20x + 10
12x^2 - 26x + 10 - 40 = 0
12x^2 - 26x - 30 = 0
Divide through by 2
6x^2 - 13x - 15 = 0
Solve using factorization method
(6x + 5) (x - 3) = 0
6x + 5 = 0
6x = -5
x = -5/6
Or
x - 3 = 0
x = 3
The extraneous solution is x = -5/6
Length = 3x - 5 ft
= 3(3) - 5
= 9 - 5
= 4 ft
Width = 2x - 1 ft
= 2(3) - 1
= 6 - 1
= 5 ft
