URGENT!!!!!! Find the value of q in the following system so that the solution to the system is——
valkas [14]
<h3>Answer:  Q = 8</h3>

====================================================

Explanation:

The left hand side of the first equation is x-3y

The left hand side of the second equation is 2x-6y = 2(x-3y). Note how it's simply double of the first expression x-3y

If we multiply both sides of the first equation by 2, we get

x-3y = 4

2(x-3y) = 2*4

2x-6y = 8

Meaning that 2x-6y = 8 is equivalent to x-3y = 4. Both produce the same line leading to infinitely many solutions. Each solution will lay along the line x-3y = 4.

We can say each solution is in the set {(x,y): x-3y = 4}

Which is the same as saying each solution is of the form (3y+4,y)

Mr. shaw graphs the function f(x) = –5x 2 for his class. the line contains the point (-2, 12). what is the point-slope form of t
True [87]

y - 12 = -5(x + 12) is the required equation.

f(x) = -5x + 2

let f(x) = y

y = -5x + 2

y = -5x + 2

comparing it to y = mx + c

m = -5

The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The equation of a line is an equation that is satisfied by each and every point on the line. This means that a linear equation in two variables represents a line.

The point slope equation formula is

y - y₁ = m(x - x₁)

Now the equation of line containing (-2,12) is

y - {y}_1= m(x - {x}_1)\\

y - 12 = -5(x + 12)
