<span>When you add fractions, the denominators must be the same, so you may have to generate equivalent fractions by using the lowest common multiple of all the denominators. For subtraction of fractions, you use the same method. When multiplying fractions, you can only multiply the numerators together, and the denominators together. </span>
The answer is D because the slope formula shows that the answer is C or D and C would not make sense because the y intercept is impossible
Answer:
A
Step-by-step explanation:
Vertex appear to be at (5,115)
A) h = -b/2a
= -(20)/2(-2) = 5
k = -2(5²) + 20(5) + 60 = 110
You would have 38 quarters=$9.50 and you would have 12 nickels=$.60, which means that you would have a total of $9.50+$.60=$10.10 and then 38+12=50 coins.
