If the y-coordinates of the given vertices and foci are the same, then the major axis is parallel to the x-axis. Use the standard form (x−h)2a2+(y−k)2b2=1 ( x − h ) 2 a 2 + ( y − k ) 2 b 2 = 1 . If the x-coordinates of the given vertices and foci are the same, then the major axis is parallel to the y-axis.
Hope I helped you! :)
Below is a drawing I did!
-5a - 12a can also be rewritten as:
-5a + -12a, which would equal -17a
The dinner will cost $250 today.
<u><em>Explanation</em></u>
The price of a four-star dinner was $100 two decades ago and now the cost of the dinner is 250% of what it was 20 years ago.
So for finding the current cost, we will find 250% of $100 .
First we need to make 250% as decimal form after dividing it by 100. So....
250% = 
Now we will multiply this 2.50 with $100 for getting the current cost of the dinner.
Thus, the current cost 
100% ............. 2.20
40% ............. x
-----------------------------
x=40*2.20/100
x=88 / 100
x= 0.88
The answer is x=0.88
Answer:
First recipe needs = 3/8
Second recipe needs = 5/8
Step-by-step explanation:
Given:
Two recipes needs butter = 1 pound
One recipe needs 1/4 pound more
Find:
Each recipe needs butter
Computation:
Assume;
First recipe needs = x
Second recipe needs = x + (1/4)
Two recipes needs butter = First recipe needs + Second recipe needs
x + x + (1/4) = 1
2 x = 1 - (1/4)
2 x = 3/4
x = 3/8 pound
First recipe needs = 3/8
Second recipe needs = x + (1/4) = (3/8) + (1/4) = 5/8
Second recipe needs = 5/8
