the variables x and y have a proportional relatinship and y=2/5 when x=5/8 which equation represents this relationship
mafiozo [28]

The equation is y = 16/25 x

lets find the proportional relationship,

y = kx

2/5 = k * 5/8

k = (2/5) /  (5/8)

k = 16/25

so if k, constant is 16/25

equation is:

y = 16/25 x

<h3>What are proportional relationships?</h3>

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

<h3>How do you find the proportional relationship in an equation?</h3>

The equation that represents a proportional relationship, or a line, is y = k x , where is the constant of proportionality. Use k = y x from either a table or a graph to find k and create the equation.

A curve has equation<br> y = x²(x - 2)<br> Work out the gradient of the curve at the point (3,9).
slava [35]

Answer:

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

dy/dx = 3 x^2 - 4 x

At x = 3  dy/dx = 3 * 9 - 4 * 3 = 15  The slope (gradient) of the curve

Does the equation 6x+35=-6x+35 have infinitely many ,one or no solution​
marissa [1.9K]

Answer:

One solution

Step-by-step explanation:

6x+35=-6x+35

Add 6x to both sides (addition property of equality)

12x+35=35

Subtract 35 from both sides (subtraction property of equality)

12x=0

Divide both sides by 12 (division property of equality)

x=0

Therefore there is only one solution, 0.
