The correct answer is B=4
Wait it says ur in high school so u can't be over 30. that isn't possible. So what's the problem here? not good at math.
Answer:
5x+4y=85-
Slope = -2.500/2.000 = -1.250
x-intercept = 85/5 = 17
y-intercept = 85/4 = 21.25000
2x+3y=41-
Slope = -1.333/2.000 = -0.667
x-intercept = 41/2 = 20.50000
y-intercept = 41/3 = 13.66667
Complementary angles are two angles that total 90°, so yes, you are correct.
ANSWER: The answer is (B) the sum of the measures of the two angles is 90°.
Hope this helps! :)
The rule of 72 says to divide 72 over the interest rate without the percent sign attached to it. This means we divide 72 over 9.6 to get 72/9.6 = 7.5
So the money doubles every 7.5 years. When another 7.5 years rolls around, a total of 2*7.5 = 15 years has gone by. At this point the money is roughly 4 times that of the original amount deposited.
