Answer:

-3/4 is the slope

Step-by-step explanation:

3x + 4y = 1/2

4y = -3x + 1/2

y = -3/4x + 0.125

m = -3/4

<h3><u>Answer</u> :</h3>

Let numerator of fraction be x and denominator be y.

∴ Fraction = x/y

★ <u>Part - A</u> :

:\implies\tt\:\dfrac{x\times 4}{y-2}=2

:\implies\tt\:4x=2(y-2)

:\implies\tt\:4x=2y-4

:\implies\tt\:2y=4x+4

:\implies\bf\:y=2x+2\:\:\dots (1)

★ <u>Part</u><u> </u><u>-</u><u> </u><u>B</u> :

:\implies\tt\:\dfrac{x+15}{2y-2}=\dfrac{9}{7}

:\implies\tt\:7(x+15)=9(2y-2)

:\implies\tt\:7x+105=18y-18

From equation (1)...

:\implies\tt\:7x+105=18(2x+2)-18

:\implies\tt\:7x+105=36x+38-18

:\implies\tt\:29x=105-18

:\implies\tt\:x=\dfrac{87}{29}

:\implies\boxed{\bf{x=3}}

:\implies\tt\:y=2x+2

:\implies\tt\:y=2(3)+2

:\implies\boxed{\bf{y=8}}

∴ Fraction = x/y = 3/8

The sum of two numbers is 64 and their differences in 10. Find the numbers
uranmaximum [27]

Answer:

37 and 27

Step-by-step explanation:

Lets say that the two numbers are x and y. We get the equations x + y = 64 and x - y = 10. We can then add these two equations together to get, 2x = 74. Then we divide by two on both sides and get x = 37. We then plug this value back into the second equation and get that 37 - y = 10. We can simplify this and we get that y = 27. So our two numbers are 37 and 27.
