Using the transformation T: (x, y) (x + 2, y + 1), find the distance named. Find the distance BB'

AnnZ [28]

Answer:

$\sqrt{5}\ units$

Step-by-step explanation:

we know that

The rule of the translation is equal to

$(x,y)-----> (x+2,y+1)$

That means

The translations is $2$ units to the right and $1$ unit up

Let

$(x,y)$ -------> the coordinates of point B

$(x+2,y+1)$ ------> the coordinates of point B'

Find the distance

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute

$d=\sqrt{((y+1)-y)^{2}+((x+2)-x)^{2}}$

$d=\sqrt{(1)^{2}+(2)^{2}}$

$d=\sqrt{5}\ units$

Solve the system of equations using substitution or elimination. Show all work for credit.

Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
$y = \frac{ - \frac{1}{2} x + 2}{3} \\ y = - x + 9$

Since both expressions are equal to y, you have to equal both expressions like this:
$\frac{ - \frac{ 1}{2}x + 2 }{3} = - x + 9$
Now you can solve the equation:
$- \frac{1}{2} x + 2 = 3( - x + 9) \\ - \frac{ 1}{2}x + 2 = - 3x + 27 \\ \\ - \frac{1}{2} x + 3x = 27 - 2 \\ \frac{5}{2} x = 25 \\ x = \frac{(25)(2)}{5} \\ x = 10$
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result

$y = - (10) + 9 \\ y = - 1$
So, the answer is x=10 and y=-1

Two angles of a triangle have a sum of 110. the sum of all three angles is 180 .what is the measure of the third angle

defon

Well by the looks of it The missing angle is 70 degrees. I say this because 110 + 70 = 180. If you were asking what were the two angles just divide.
