Your vertex is (8,7)
First find the x intercept
-2/2a
X = 16/2
X = 8
Substitute the value x and solve for y
Youd get 7
Hence
(8,7)
In this question, it is important to understand the words of the problem and then note down the details already provided in the problem. This will make the solving of this problem easier.Now coming to the details already given.
Distance walked by Laura to reach school each day = 3/5 mile
Distance walked by Isaiah to reach school is 3 times that of Laura and it is already given in the question.
Then
The distance walked by Isaiah to reach school each day = (3/5) * 3
= 9/5
= 1 4/5
So Isaiah walks a distance of 1 4/5 miles each day for reaching school. I hope that the procedure of doing such problems is clear to you and yiou can attempt such problems in future without needing any help.
Hope this helps!
The answer would be 18+54 because when you distribute the 6 to the numbers that are inside the parenthesis (6*3=18 6*9=54) When you add 18 and 54 together I would get 72. 18+54 is 72. 18+9 is 27. 9+15 is 24. 6+54 is 60. Pick the one that gives you an answer of 72 which was 18+54. I hope this helped you!
Answer:
8 nickels and 9 dimes
Step-by-step explanation:
If all were dimes, the value would be $1.70. It is $0.40 less than that. Changing a dime for a nickel reduces the value by $0.05, so there must have been $0.40/$0.05 = 8 such changes.
There are 8 nickels and 9 dimes.

<em>Check</em>
8 · 0.05 + 9 · 0.10 = 0.40 + 0.90 = 1.30 . . . the answer checks OK
You might have made an error the first time you solved for x. I got x = -0.5.
When you have your log base 4, the way you cancel that out is by making 4 the base on both sides, so you get 4^(log4) to reduce to 1, and you're left with:
2x + 3 = 4^(1/2) ... Simplify
2x + 3 = 2
2x = -1
x = -1/2
If you plug that back in, everything checks out. Maybe double check your use of logarithm/exponent properties?
