mezya [45]

Answer:

Step-by-step explanation:

y=mx+b

Slope is also known/substituted by the variable m. Therefore we can come to the conclusion that m=-6.

y=-6x+b

Y-intercepts are substituted with the variable b. Therefore we can substitute the 2 as b, meaning b=2.

Determine if the equation y = 2/5 x − 4 y=25x-4 represents a proportional relationship. If so, determine the constant of proport
Vilka [71]

Answer:

The linear equation represents a proportional relationship and its constant of proportionality is k = \frac{2}{5}.

Step-by-step explanation:

A proportional relationship exists when the following relationship is observed:

u = k\cdot v

Where:

u - Dependent variable.

v - Independent variable.

k - Proportionality constant.

If y =\frac{2}{5}\cdot x - 4 and v = x and u = y+4, the following expresion is found:

y = \frac{2}{5}\cdot x -4

y + 4 = \frac{2}{5}\cdot x

u = \frac{2}{5}\cdot v

The linear equation represents a proportional relationship and its constant of proportionality is k = \frac{2}{5}.

A foam toy is 2 inches wide. It doubles in size for every minute it is in water. Write an expression for the width of the toy af
Solnce55 [7]

it would be 2(2^5), which is two times two to the fifth power. you take the original size and double it for every minute, which is like squaring it, but to the power of five, because it doubles once every minute for five minutes. i hope this makes sense!:)
