Solve the following equation : 7x/15-1=22
miskamm [114]
\frac{7x}{15-1} =22
-----------------
To solve this all it takes is two simple steps
Simplify \frac{7x}{15-1} =22
1/2x =22
------------------------
Multiply both sides by 2
2 · \frac{1}{2} = 2 · 22
x = 44

The right isosceles triangle PQR has vertices P(3, 3), Q(3, 1) and R(x, y) and is rotated 90 degrees counterclockwise about the
Jlenok [28]
For the answer to the question above, since the triangle is isosceles, the two legs have equal length. The coordinates of two vertices are given
P(3,3)
Q(3,1)
Assuming that PQ and QR are the legs of equal length, the distance between Q and R must be the same as the distance between P and Q
d = √[(3-3)² + (3-1)²
d = 2
Therefore, the coordinates of P is

A transformation that maps the vertex A( 3 , 4 ) to A’ ( -4 , 3 ) is
Katen [24]

Answer:

"A translation of 7 units to the left followed by a translation of 1 unit down".

Step-by-step explanation:

There are multiple transformations that map one point into another, here is one example that works particularly for translations, which are the simplest (and usually the most used) transformations.

Suppose that we have the point (a, b) which is transformed into (a', b')

Then we have a horizontal translation of (a' - a) units followed by a vertical translation of (b' - b) units.

(the order of the translations does not matter, is the same having first the vertical translation and then the horizontal one).

Here we have the point A (3, 4) transformed into (-4, 3)

Then we have a horizontal translation of ((-4) - 3) = -7 units followed by a vertical translation of (3 - 4) = -1 units.

Where a horizontal translation of -7 units is a translation of 7 units to the left, and a vertical translation of -1 unit is a translation of 1 unit down.

Then we can write this transformation as:

"A translation of 7 units to the left followed by a translation of 1 unit down".
