-3x + 1

The factors of 117 are 1, 3, 9, 13, 39, and 117. These are the only numbers that divide into 117 evenly, without a remainder.

3x - y = -4

3x - y = 0

Those lines do not intersect. They are parallel. You can demonstrate by solving either of them for one of the two variables, then plugging it's value into the other:

3x - y = -4

∴y = 3x + 4

Now substitute:

3x - y = 0

∴ 3x - (3x + 4) = 0

∴ 3x - 3x - 4 = 0

∴ -4 = 0

This result is obviously incorrect, indicating that the lines do not intersect.

20x=130

x=130/20

x=6.5 or 13/2

No, it isn't.

It is equal to 2x because if you were to replace the "x" with a number say, 2 for example so 2 + 2 would be 4 and 2 times 2 would also be 4 which is what "2x" stands for (2 times x). So then if you had x + x you would get 2x.

pi never ends but we don't know many the there is someone that claims to know 20million digits if he said a number per second it would take about 2 years so examiners say things like 2000-3500 and he says them and he has not been proved wrong yet.

Rate of flow varies as R^4 where R is the radius or

Rate of flow = (k) x (R^4)

It SHOULD always be less than the divisor...

Otherwise your answer is wrong.

if you meant it as you wrote it, then the equation is just a line.

if you meant: 2x^2-12x+16, then:

y=2(x^2-6x)+16

y=2(x^2-6x+9)+16-18. You have to subtract 18, not 9, because it is being multiplied by 2.

y=2(x-3)^2 - 2

2/x + 5

Urban integration refers to the process of creating inclusive, cohesive urban environments where diverse communities can coexist and thrive. It involves the integration of various social, economic, and cultural groups within a city, promoting equitable access to resources, services, and opportunities. This approach aims to reduce spatial and social segregation, fostering collaboration and interaction among residents to enhance overall quality of life and urban sustainability.

Gottfried Wilhelm Leibniz is credited with defining the standard notation for integrals.

Your question is a little nebulous, but I think this is what you mean...

32 = 9x + 5

Thus we want to get x equal to the scalar (i.e. number)

move 5 on the other side through subtraction (because 5 is positive already...we use the opposite operation to "flip" it)

32 - 5 = 9x

27 = 9x

Now, we divide each side by 9 to get x alone.

27/9 = 9x/9

27/9 = 1x

27/9 = x

3=x

Thus...X=3

if this question is -6 times 3 plus 15 then = -21

if its -6 plus 3 plus 15 then = 12

if its -6 times 3 plus 1.5 then = -16.5

if it is -6 plus 3 plus 1.5 = -1.5

3x+2y=43 where x=(-4+y)/2 =0.5y-2

3(0.5y-2)+2y=43

1.5y-6+2y=43

3.5y-6=43

3.5y=49

y=49/3.5 which is the same as (49x2)/7 =14
