2% of 10000 = $200
3 years = $600
therefore stephen pays back 10000+600 = $10600
Hey, looks like when she doesn't study, she ALWAYS fails. Don't mean to insult though.
Let's see the difference between the three numbers. 63-58=5. 68-63=5.
We know the difference between each assessment she scores is 5 now!!
Let's put it to use.
Although you don't have multiple choice answers...
after 4 assessments(not including first 3), her score will be above 85!!
Including the first 3 assessments, her score would be above 85 after 7 assessments!!
anyways, I hope this helps!!
First convert the 6 1/2 gallons into 6 3/6.
Now, subtract 3 5/6 from 6 3/6.
The answer is 2 4/6
(3b) / (5b - 7) = 8/11
cross multiply
8(5b - 7) = 11(3b)
40b - 56 = 33b
-56 = 33b - 40b
-56 = -7b
-56/-7 = b
8 = b
Answer: Choice D
y = -(x - 2)^2 + 7
===========================================================
Explanation:
The highest point is (2, 7) so this is the vertex.
In general, the vertex is (h, k). We can say that h = 2 and k = 7.
The vertex form
y = a(x-h)^2 + k
updates to
y = a(x-2)^2 + 7
----------------
Note that the graph goes through (0,3) which is the y intercept. Plug those x,y coordinates into the equation above to solve for 'a'
y = a(x-2)^2 + 7
3 = a(0-2)^2 + 7
3 = a(-2)^2 + 7
3 = a(4) + 7
3 = 4a + 7
4a+7 = 3
4a = 3-7
4a = -4
a = -4/4
a = -1
----------------
Therefore, we have
y = a(x-2)^2 + 7
update to
y = -1(x-2)^2 + 7
which is the same as
y = -(x - 2)^2 + 7
and that's why the answer is choice D
