Answer:
y is 1/3 of x
Step-by-step explanation:
x:y is 3:1
mathematically, we have this as;
x/y = 3/1
x = 3y
or y = x/3
So the correct answer is that y is 1/3 of x
what does the solution to the system c,p reprent in this situation 5c+4p=18.40
2c+4p=11.20
Answer:
4 and 4/15=c. 2 and 2/15=p.
Step-by-step explanation:
I am younger than 12 i dont have much experience; done 2 or 3 problems like this...
first lets make it simpler...
2c+4p=11.20 is the same as c+2p=5.6
then subtract one from the other and you get 4c+2p=12.8
simplify again 2c+p=6.4
so the ratio of c to p is 2:1. Multiply 6.4 by 2/3 to get what c is... 64/15
64/15 is 4 and 4/15. then divide by 2 to get what p is so 64/15÷2=32/15 which is 2 and 2/15.
These are from the same question
Answer:
a. 25%
b. 6.5%
c. 20%
Step-by-step explanation:
f (x) = -x2 + 164x - 64, f(x) = -4x2 - 10x + 84, f(x) = 3x² + 24.
Answer:
You need to ask a question for someone to answer it.
Are you looking for their derivatives?
-x² + 164x - 64 => -2x + 164
-4x² - 10x + 84 => -4x - 10
3x² + 24 => 6x
Indefinite Integrals?
-x² + 164x - 64 => -x³/3 + 82x² - 64x + C
-4x² - 10x + 84 => -4x³/3 - 5x² + 84x + C
3x² + 24 => x³ + 24x + C
Want them factored?
-x² + 164x - 64 => has no factors
-4x² - 10x + 84 => 2(2x - 7)(x + 6)
3x² + 24 => 3(x² + 8)
We can't ensure a proper answer if you don't ask the question.

It takes 900 pounds of steel to make one steel beam. How many beams can be made from 6,300 pounds of steel?
Answer:
7
Step-by-step explanation:
6,300 divide by 900 would equal 7
Answer:
7 beams
Step-by-step explanation:
To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:
6,300 ÷ 900 = 7
So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

Daniel and Lisa are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. Daniel sold 5 rolls of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $74. Lisa sold 1 roll of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $58. Find the cost each of one roll of plain wrapping paper and one roll of holiday wrapping paper
Answer:
P = 4 & H = 18
Step-by-step explanation:
Daniel : 5 plain paper + 3 holiday paper = 74, 5P + 3H = 74 . Lisa : 1 plain paper + 3 holiday paper = 58, P + 3H = 58 . Solving two equations, P = 4 & H = 18
Answer the question............
Hey there!
The answer to your first question is 4.5 inches by 6 inches.
We can solve this by doing 3 x 1.5 and 4 x 1.5, which equals 4.5 and 6.
The answer to the second part is 27 inches²
The formula for area is length times width, so you can do 4.5 x 6
The answer to the third part is Ralph is incorrect because he probably found the area of the original dimensions, and then multiplied it by 1.5. You have to find the actual dimensions first, and then find the area.
Hope this helps. Good luck, have a great day, and let me know if there's more.

What is the equation of a line that is parallel to 2x +3y = 3 and passes through the point (3, -4) ?
Answer:
2x + 3y = -6
Step-by-step explanation:
The equation of the new line will be identical to that of the given line except that the constant term will differ.
Start with the given 2x + 3y = 3 and replace x with 3 and y with -4. We get:
2(3) + 3(-4) = C, and C = 6 - 12 = -6
The equation of the new line is therefore 2x + 3y = -6

X-axis is first and Y-axis
Answer:
Slope: [tex]m=-\frac{1}{2}[/tex]
y-intercept: [tex](0,-1)[/tex]
Equation: [tex]y=-\frac{1}{2}x-1[/tex]
Step-by-step explanation:
Slope-intercept form of an equation is written as [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.
The slope of a line that passes through the points [tex](x_1,\: y_1)[/tex] and [tex](x_2, \: y_2)[/tex] is [tex]m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}[/tex]. Using the coordinates [tex](-2, 0)[/tex] and [tex](2,-2)[/tex] as given in the problem, we have slope of this line to be:
[tex]m=\frac{-2-0}{2-(-2)}=\frac{-2}{4}=-\frac{1}{2}[/tex].
Now using this slope we've found and any point the line passes through, we can find the y-intercept of this equation:
[tex]0=-\frac{1}{2}(-2)+b, \\ b=-1[/tex]
Therefore, the equation of this line in slope-intercept form is [tex]\fbox{$y=-\frac{1}{2}x-1$}[/tex].
The y-intercept occurs when [tex]x=0[/tex]:
[tex]y=-\frac{1}{2}(0)-1, \\\\y=1[/tex]
Thus, the y-intercept is
[tex](0, -1)[/tex]
