When a system of two linear equations has no solution, how do the graphs of the equations appear?​
amm1812

Answer:

parallel lines that never intersect.

Step-by-step explanation:

When dealing with two linear equations that have no solution, it means that they usually have two variables and are part of a system of equations. Such an example would be the following two equations

2x - y = 2

4x - 2y = 8

These two equations would be part of the same system and they have no solution because there is no pair of values that will give a valid solution to both for the variables x and y. In a graph these equations would appear as parallel lines that never intersect. This is why no solution is found, because there is no intersection.

Given the function f(x)= 2|x+6|-4, for what values of x is f(x)=6?
Paraphin [41]

Answer:

x = -1 or x = -11

Step-by-step explanation:

f(x)= 2|x+6|-4

2|x+6|-4 = 6

2|x+6| = 6+4

2|x+6|=10

|x+6| = 10/2

|x+6| = 5

x+6 = ±5

x = ±5 - 6

x = -1 or x = -11

PLEASE HELP Evaluate the limit, if it exists. Show work. lim_(x->5)((x^(2)-3x-10)/(2x-10))
gayaneshka [121]

Answer:

lim \: x \: —>5 \:  \:  \frac{ {x}^{2} - 3x - 10 }{2x - 10}  \\  \\ lim \: x \: —>5 \:  \:  \:  \frac{(x - 5)(x + 2)}{2(x - 5)}  \\  \\ lim \: x \: —>5 \:  \:  \frac{(x + 2)}{2}   =  \frac{5 + 2}{2}  =  \frac{7}{2}  \\  \\  \\  =  \frac{7}{2}  = 3.5

I hope I helped you^_^

Find the point at which the line with parametric equations x = 2 3t, y =-4t, z =5 t intersects the plane 4x 5y -2z=18
sashaice [31]

It looks like you have

\begin{cases}x=2+3t\\y=-4t\\z=5+t\end{cases}

Substituting these in to the plane equation, we have

4x+5y-2z = 4(2+3t) + 5(-4t) - 2(5+t) = -2-10t = 18 \\\\ \implies-10t = 20 \implies t = -2

When t=-2, we get the point

\begin{cases}x=2+3(-2)\\y=-4(-2)\\z=5+(-2)\end{cases} \implies (x,y,z) = \boxed{(-4,8,3)}
