Correct formula is y = kx, where k is the "constant of proportionality."

If y = 9 when x = 2, then 9 = k(2), or k = 9/2.

Then y = (9/2)x.

If x = 3, y = (9/2)(3) = 27/2 (answer)

Answer:

y = -4/5x + 2/5

Step-by-step explanation:

$4y=5x+3\\write -in ; y=mx+b -form\\y = \frac{5}{4} x + \frac{3}{4} \\m = 5/4\\m_1m_2 = -1\\5/4m_2 =-1\\m_2 = -4/5\\ (3,-2)\\x = 3\\y = -2\\y = mx+b\\-2 = -\frac{4}{5}(3) +b\\-2 = -12/5 +b\\-2+12/5 = b\\2/5 = b\\m = -4/5\\Substitute -new-values-into-slope-intercept-form\\y = mx+b\\y = -4/5x + 2/5$

What is 6/5 divided by 4/10

Sidana [21]

Your answer is 0.03 because you have to make the 5 equal to the ten and that would be 10 then change the division to multiplication and just multiply across then you simplify it.

What is the value of x in the equation 4x+8y=40, when y=0.8?

lubasha [3.4K]

4x+8y=40
0.8*8=6.4
4x+6.4=40
40-6.4=33.6
4x=33.6
33.6\4=8.4
