Answer:

(x, y) → (x – 8, y + 11)

Step-by-step explanation:

We are given the vertices of the triangle with their respective coordinates. For the vertex L, the translated coordinates is also given. So, from the original coordinates of L and the new coordinates, we can get the rule used during translation:(7, -3) -> (7 + a, -3 + b) = (-1, 8)7 + a = -1a = -8

-3 + b = 8b = 11

You can always add or subtract same value to/from both sides of equation. The same is true about multiplication and division.

In your case you have to subtract x from both sides of equation in order to get rid of it on the left side:
$x+2y-x=8-x$
$2y=8-x$

But it's easier to remember that if you want to move some member of equation to other side, you just have to change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):
$+x+2y=+8$

Move 2y to the right side:
$+x=+8-2y$

Move 8 to the left side:
$+x+2y-8=0$

Move both x and 2y to the right side:
$0=8-x-2y$

The pizzeria has 7% of 10 of their cheese and now we have to figure out how many cheese is in 7% that is left?

Leto [7]

10 mean 100%
x mean 7%
--------------------
x=7*10/100 = 70/100 = 0,7

Ethan planted a tree that is 37.5 inches tall. If the tree grows 3 inches each year, how long will it take for the tree to reach

icang [17]

54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=

the line passing through the points (1,2) and (x, 5) is perpendicular to a line that has a slope of 1/3. what is the value of x

gogolik [260]

Answer:

x= 0

Step-by-step explanation:

Let's form an equation using the slope of the line.

$\boxed{gradient = \frac{y1 - y2}{x1 - x2} }$
