What is the rate of change of y=-4/9x+5

WARRIOR [948]

Answer:

Rate of change of y is $- \frac{4}{9}$

Step-by-step explanation:

$y = - \frac{4}{9} x + 5 \\ \\ differentiating \: with \: respect \: to \: x \\ \\ \frac{dy}{dx} = - \frac{4}{9} \frac{d}{dx} x + \frac{d}{dx} 5 \\ \\ \frac{dy}{dx} = - \frac{4}{9} .1 + 0 \\ \\ \huge \red{\frac{dy}{dx} = - \frac{4}{9} } \\ \\ rate \: of \: change \: of \: y =- \frac{4}{9}$

Y + 4 = 1 . 5 ( x − 4 ) how do you solve this linear equation for standard form in algebra

Lena [83]

Standard form is ax+by=c
Steps:
y + 4 = 1.5(x - 4)
y + 4 = 1.5x - 6
-1.5x + y = -10 is the standard form.

The ration of red marbles to white ones is 13 to 12. If there are 3,081 red marbles how many white ones are there?

Black_prince [1.1K]

Answer:

2844

Step-by-step explanation:

13 is to 12 as 3081 is to x. 13/12 = 3081/x. 12 * 3081 = 13x.

36972 = 13x. divide both sides by 13, you're left with 2844.
