Answer:
Step-by-step explanation:
The given functions are:
and
We want to to find
Note that:
We substitute the functions to obtain:
We now substitute x=7, to get:
This implies that
Answer:
Option (8).Plane BPQ
Option (9).Plane OPB
Step-by-step explanation:
Any plane is described by three different points lying on the the same surface.
And planes having common edge will have the common points of the given edge.
Therefore, planes given in the picture which will have the common side BP are,
Plane BPQ and plane OPB.
Therefore, Option (8) and Option (9) are the answer.
Answer: (0, -1 ), (1, -1), (2, 1)
<u>Step-by-step explanation:</u>
Set the exponent equal to zero - <em>that is your anchor point</em>.
Then choose an x-value less than and greater than the anchor point.
First option:
y=money saved
x=number of months
y=30x+500
Second option:
y=50x+200
We have this system of equations:
y=30x+500
y=50x+200
We can solve this system of equations by equalization method
30x+500=50x+200
30x-50x=200-500
-20x=-300
x=-300/-20
x=15
so;
y=30x+500
y=30(15)+500
y=450+500
y=950
Answer; after 15 months, she would save the same amount using either option, the amount saved in either option will be $950.
