Take the opposite recporical of the slope give...so the so that would be. 2.

when two lines are perpendicular, switch the numerator and denominator of the given slope, add a negative sign in the front, you will have the slope of the other line. 
if the slope is an integer, for example 3, it is the same as 3/1, the slope of the perpendicular line is then negative 1/3, (-1/3)
in this case, the slope of CD is -(-2/1)=2

In what line do planes A and QRV intersect?
matrenka [14]

In this question, we have to fin the line of intersection of the planes A and QRV.

We have to see the given figure and find the line on which the two planes A and QRV meets.

Lines SR,TS, WT and WQ are not on plane QRV.

The only line which passes through both planes is  QR.

And that's the line of intersection of the two planes.

Find the x intercept and the y intercept of the graph of the equation <br> 2x+4y=8
maksim [4K]

Answer:

x-intercept: 4

y-intercept: 2

Step-by-step explanation:

finding the x-intercept:

first, substitute y = 0.

2x + 4 x 0 = 8

then, remove the 0.

2x + 0 = 8

then, divide both sides. 2x = 8

so, x = 4.

finding the y-intercept:

first, substitute x = 0.

then, solve.

2 x 0 + 4y = 8

so, y = 2.

Use the given graph to determine the limit, if it exists. A coordinate graph is shown with a downward sloped line crossing the y
vesna_86 [32]
For the limit approaching 3 from the right, you want to follow the line to the right of x = 3. From the graph you're describing it sounds like that's y = -3. \lim_{x \to 3} f(x)=-3

The RHS limit is -3 even though f(3) = 7

HELP PLZ! I do not understand this!!
neonofarm [45]
PART 1
If I have graph f(x) then graph f(x + 1/3) would translate the graph 1/3 to the left.

For example, I have f(x) = x².Then
f(x + 1/3) = (x + 1/3)²

I draw the graph of f(x) = x² and the graph of f(x) =  (x + 1/3)² on cartesian plane to know what's the difference between them.


PART 2
If I have graph f(x) then graph f(x) + 1/3 would translate the graph 1/3 upper.

For example, I have f(x) = x².Then 
f(x) + 1/3 = x² + 1/3

I draw the graph of f(x) = x² and the graph of f(x) = x² + 1/3 on cartesian plane to know what's the difference between them.


SUMMARY
f(x+1/3) ⇒⇒ <span>f(x) is translated 1/3 units left.
f(x) + 1/3 </span>⇒⇒ <span>f(x) is translated 1/3 units up.</span>
