Solve for t in terms of the other variables.
k= 3tm + rs

Answers

Answer 1

Answer:

              [tex]t=\dfrac{k-rs}{3m}[/tex]

Step-by-step explanation:

It's like solving any equation, except we have letters instead of numbers .

k = 3tm + rs           {subtract rs from both sides}

k - rs = 3tm            {divide both sides by (3m)}

[tex]\dfrac{k-rs}{3m}=t[/tex]              {swap sides}

[tex]t=\dfrac{k-rs}{3m}[/tex]            m≠0    

{m must be ≠0 because  you cannot divide by 0. There is no t for m=0}

if a system of linear equation has an infinite number of solutions, what do you know about the graph of the system?

a. the lines intersect at one point
b. the lines are parallel
c. the lines are the same
d. the lines cannot he graphed

Answers

Answer:

c. the lines are the same

Step-by-step explanation:

A system of linear equations has an infinite number of solutions because the lines are the same. The correct answer would be an option (C).

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

If a system of linear equations has an infinite number of solutions, it means that the equations are equivalent and represent the same line in the coordinate plane.

Therefore, the graphs of the two equations will be the same line, meaning that the lines are coincident. They won't intersect at one point, nor will they be parallel, as the definition of an infinite number of solutions is that they are the same line. And they can be graphed, as they represent a single line in the coordinate plane.

Hence, the correct answer would be option (C).

Answers

Answer: 8

Step-by-step explanation: Given:

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(

y= x squared +2x - 2

Answers

Answer:

There are no simple factors to this expression.  You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process.  You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2.  We can however solve for x:

[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]
