Explain what makes two quantities proportional

1 answer:

They both have a relationship such as positive or negative correlation.

Assuming that the proportional relationship that the object has and k is directly proportional, we can say that it may equal to the size of the existing switched row, speculating again that the size of the table is equilateral –equal in size. Then there’s no new change. Hence direct proportionality and indirect proportionality is what matters in the relationship since k will define the number of which will change the course of the equation, somehow k is like the independent variable in the given formula.

-5(11-3t) = -6t - 4 what does t equal?

Inessa [10]

-5(11-3t) = -6t -4

distribute -5 to the parentheses

-55+15t = -6t -4

isolate t; add -6t from both sides

-55+21t = -4

add 55 from both sides

21t = 51

divide t

t = 2.4 (rounded)

What is the value of f(-2) if f(x) = - 3x2 + 4x - 1

pashok25 [27]

Given the function below:

$\large{f(x) = - 3 {x}^{2} + 4x - 1}$

To find f(-2), we substitute x = -2 in the equation. Since f(-2) means the value of f(x) at x = -2.

$\large{f( - 2) = - 3 {( - 2)}^{2} + 4( - 2) - 1}$

Replace x-term to -2 and evaluate.

$\large{f( - 2) = - 3(4) - 8 - 1} \\ \large{f( - 2) = - 12 - 8 - 1 \longrightarrow f( - 2) = - 21}$

Answer

f(-2) = -21

What is 4|2y-3|-1=11

umka2103 [35]

implifying 4[2y + -3] + -1 = 11 Reorder the terms: 4[-3 + 2y] + -1 = 11 [-3 * 4 + 2y * 4] + -1 = 11 [-12 + 8y] + -1 = 11 Reorder the terms: -12 + -1 + 8y = 11 Combine like terms: -12 + -1 = -13 -13 + 8y = 11 Solving -13 + 8y = 11 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '13' to each side of the equation. -13 + 13 + 8y = 11 + 13 Combine like terms: -13 + 13 = 0 0 + 8y = 11 + 13 8y = 11 + 13 Combine like terms: 11 + 13 = 24 8y = 24 Divide each side by '8'. y = 3 Simplifying y = 3
