Which equation represents a linear function? y=4/x+1, y=2/3x -1/2

Mathematics
1 answer:
Tom [10]3 years ago

Answer:

y = 2/3x - 1/2

Step-by-step explanation:

y = 2/3x - 1/2 is a linear function. It contains a slope and a y-intercept and every x value will produce a unique y value.

y = 4/x + 1 is a rational function, as it contains a fraction.

Easy algebra question below first correct answer gets brainliest
Alexxx [7]

Answer:

3

Step-by-step explanation:

Easy pythagorean theorum question.

The law states that "A squared plus B squared, equals C squared."

A and B are the two sides that border the 90 degree mark.

C is the hypotenuse or the longest side/diagonal.

Since we know C and A (I chose to use A because why not) we can fill in the equation with what we know

2^2 + ?^2 = \sqrt{13^{2} }

So

4 + ?^2 = \sqrt{13^{2} }

Since the 13 is already squared in side of a root, it stays as 13

4 + x^2 = 13

4 - 4 + x^2 = 13 - 4

x^2 = 9

x^2 root = root of 9

x = 3

The missing side is 3.

Or you could use an online calculator xD

Simplify each expression <br> 4+8(-2n+3)
artcher [175]

Answer:

  28 -16n

Step-by-step explanation:

Use the distributive property, then collect terms.

  4 +8(-2n +3)

  = 4 +8(-2n) +8(3)

  = 4 -16n +24

  = 28 -16n

_____

This could also be written

  -16n +28

but then the leading sign would be negative. Sometimes leading minus signs get lost, so I prefer the first term to be positive.

A shopkeeper fixed the marked price of his radio to make a profit of 30 %. Allowing 15 % discount on the marked price, the radio
topjm [15]

Answer:

10.5 %

Step-by-step explanation:

Here .

let the Cost Price be 'x'

the..

by the question..

the marked price was fixed to make 30% profit

then..

the marked price will be

x+ 30% of x

= x + 30/100 × x

=x+ 0.3x

=1.3x

soo .. the marked price is 1.3x

now.. after allowing 15% discount..

the selling price will be

1.3x - 15% of 1.3x

= 1.3x - 0.195x

= 1.105x

thank you...

plzz mark me brainliest now

now..

profit made = 1.105x-x

= 0.105x

soo .

in percentage..

profit percent = profit/cp × 100%

= 0.105x/x × 100%

= 10.5 %
