<u>Answer:</u>
D) R0 , 360°
<u>Explanation:</u>
<u>We are given that the rotation is:</u>
(x,y) --------> (x,y)
This means that the point is rotated back into its original position.
This means that full rotation occurred.
Since the full rotation is 360°, therefore, the correct answer is D
<u>For the other options:</u>
<u>Rotation 90° gives:</u>
(x,y) ----------> (-y,x)
<u>Rotation 180° gives:</u>
(x,y) ----------> (-x,-y)
<u>Rotation 270° gives:</u>
(x,y) ---------> (y,-x)
Hope this helps :)
This is solving for x and y
5-8,-14+4
Answer:
Around 57.74 feet
Step-by-step explanation:
The tower and James form a right triangle, where the other two angles are 30 degrees and 60 degrees. The tangent of an angle is equivalent to the length of the opposite side divided by the length of the adjacent side, which means:
Hope this helps!
Answers D
You divide all sides by 2, get your slope form and multiply by 7
Answer:
y = - 3x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (3, - 5) ← 2 ordered pairs from table
m = = = - 3, thus
y = - 3x + c ← is the partial equation
To find c use any ordered pair from the table
Using (3, - 5 ), then
- 5 = - 9 + c ⇒ c = - 5 + 9 = 4
y = - 3x + 4 ← equation of line
