Answer:

  R''(2, 1), S''(-1, 7), T''(2, 7)

Step-by-step explanation:

Rotation 90° CCW is accomplished by the transformation ...

  (x, y) ⇒ (-y, x)

Translation 3 left and 8 up is accomplished by the transformation ...

  (x, y) ⇒ (x -3, y +8)

Together, the two transformations give ...

  (x, y) ⇒ (-y -3, x +8)

So your transformed points are ...

  R(-7, -5) ⇒ R''(-(-5)-3, -7+8) = R''(2, 1)

  S(-1, -2) ⇒ S''(-(-2)-3), -1+8) = S''(-1, 7)

  T(-1, -5) ⇒ T''(-(-5)-3, -1+8) = T''(2, 7)

A 100 centimeter stick broke into 3 pieces one piece was 7 centimeters long and another was 34 centimeters long how long was the
emmasim [6.3K]
The third piece is 59 cm long. 

Add the first two pieces up. 7+34= 41. Since the whole stick is 100 cm long, subtract 41 from 100 to find the length of the third piece. 100-41=59.

Black_prince [1.1K]
We know that
<span>
1) The degree of a polynomial is the highest degree of its terms</span>
<span>2) The leading term in a polynomial is the highest degree term</span>
<span>3) The leading coefficient of a polynomial is the coefficient of the leading term</span>  
Therefore

The coefficient of first term of a polynomial written in standard (descending order) form is the coefficient of the leading term, thus is called the leading coefficient.

If all 3 angles of a Triangle MUST equal 180°, then we know that we use the equation (for this triangle) to find the angle measurements as (180-90)/2 which means we are dividing 90/2 which is 45° for each angle. But these angles are different measures, so we have to guess upon this and say that YOUR ANSWER IS D
