CANT GET WRONGThe equation y = 4x + 4 describes the relationship between the quantities x and y. Are the quantities in a proportional relationship?
A) Yes, because the graph of the equation is a straight line.
B) No, because the graph of the equation is not a straight line.
C) Yes, because the graph of the equation passes through the origin.
D) No, because the graph of the equation does not pass through the origin.

Answers

Answer:

Option D is correct that is No, because the graph of the equation does not pass through origin.

Step-by-step explanation:

We have been given the equation:

y = 4x+4

The direct proportion means if equation follow: y=mx where m is the proportion or can say equation passes through origin.

Here, equation is y=mx+c not y=mx

In y=mx

We can see if x increases y will increase

And if x decreases y will decrease.

Therefore, Option D is correct that is No, because the equation does not pass through origin.

The correct answer would be D. because if the equation has a y-intercept (+4) than the line doesn't go through the origin.

Solve the formula A=lw for l

Answers

The solution for l in terms of A and w is: l = A / w. To solve the formula A = lw for l (length), we need to isolate the variable l on one side of the equation.

Follow these steps:

Step 1: Start with the formula: A = lw

Step 2: Divide both sides of the equation by w to isolate l:

A / w = lw / w

Step 3: Simplify the right side of the equation:

A / w = l * (w / w)

Step 4: Since w / w equals 1, we have:

A / w = l * 1

Step 5: Therefore, l is equal to:

l = A / w

So, the solution for l in terms of A and w is:

l = A / w

How can I make this a perfect square
w^2-4w+

Answers

ax^2+bx+c
if a=1, then
take 1/2 of b and square it

w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2

to make it into perfect squres, add 4
