instead of changing the 5/7 u change the 3/4
Given:
must correctly answer 80% of the questions
correctly answered questions = 26
incorrectly answered questions = 4
unanswered questions = 15
Total questions = 26 + 4 + 15 = 45
45 * 80% = 36 required correctly answered questions.
36 - 26 = 10
Out of 15 remaining questions, 10 questions must be correctly answered for Heidi to advance to the next level.
Answer:
Triangle CAT was rotated 90 degrees clockwise around the origin.
Step-by-step explanation:
The coordinate points for A and A' are (-3,3) and (3,3). The change from A to A' from quadrant 2 to 1 is a 90 degree rotation in the clockwise direction. Each of the points are equal distance from the origin (0,0) and this is the center of rotation.
The answer is C: (-3,-1)
To test if points satisfy an equation, all you need to do is test the numbers in both of the equations it provides you
Here is proof the answer is C :
<em>y > x - 2 </em>
(lets plug in point C)
-1 > -3 - 2
<u>solve </u>
-1 > -5 <em>?</em>
<em>Yes</em> this statement is true- onto the next inequalitity!
<em>y > 2x + 2 </em>
-1 > 2(-3) + 2
<u>solve </u>
-1 > -6 + 2
-1 > -4<em> ? </em>
<em>Yes, </em>this inequality is true too!
Know we know answer c (-3,-1) is the right answer!
