Answer:
X Y
-5 7
-2 1
-1 -1
2 -7
Step-by-step explanation:
If x = -5, then:
y = -3 -2(-5)
y = -3 + 10
y = 7
If x = -2, then:
y = - 3 -2(-2)
y = -3 + 4
y = 1
If x= -1, then:
y = -3 -2(-1)
y = - 3 + 2
y = -1
If x=2, then:
y = -3 -2(2)
y = -3 -4
y = -7
Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!
Answer:
D. 4.5%.
Step-by-step explanation:
Interest earned in 6 months = 572.6 - 560 = $12.60.
As a percentage this is (12.60 * 100) / 560
= $ 2.25%.
So the annual interest is 2 * 2.25
= 4.5%.
Answer: 1/7
Step-by-step explanation:
Total questions answered = 49
Harry correct answers = 42
Harry wrong answers = (49 - 42) = 7
Thus, the only fraction of wrong answers = (Number of wrong answers / Total number of questions answered)
i.e 7/49
= 1/7
Thus, harry answered 1/7 of the 49 questions wrongly.
