Answer:
C is the most reasonable answer because to add the system of equations together, you must make sure that one of the terms (whether it be the x or y value) can cancel out.
Step-by-step explanation:
Answer:
The equation for the following graph:

Step-by-step explanation:
- You first need to find the slope by using the <u>slope formula</u>:

(where
is the first point and
is the second point)
-Use the given points
and
from the graph for the formula:

Then, you solve:


After you have found the slope, use the slope
and the first point
for the <u>point-slope formula:</u>

<u>(</u>where
is the slope and
is the first point)

Then, you solve:




So, the equation for the following graph is
.
Lets assume, Sally has X pound of potatoes in her pantry.
So, 4/3 of the potatoes Sally has in her pantry = 
Now, Sally needs 2/3 pound of potatoes and this 2/3 pound of potatoes is 1/3 pound more than that 
So the representing equation will be:
(subtracting
from both sides)

(multiplying both sides by 3)
So, Sally has
pound of potatoes in her pantry.
Answer:
658.91$
Step-by-step explanation:
Find the total cost
flight cost 397$
staying at the hotel for 6 night cost 6 x 28.43£
= 170.58£ = 233.69$
breakfast for 4 morning cost 4 x 5.15£= 20.6£
= 28.22$
Total cost is 397$+233.69$+28.22=658.91$
