Onne way is to eliminate terms
-2x+7y=2
3x-5y=-14
multiply first equation by 3 and second equaiton by 2
-6x+21y=6
6x-10y=-28
add them together to cancel x terms
-6x+21y=6
<u>6x-10y=-28 +</u>
0x+11y=-22
11y=-22
divide by 11
y=-2
subsitute
-2x+7(-2)=2
-2x-14=2
add 14 to both sides
-2x=16
divide both sides by 2
-x=8
multiply -1
x=-8
x=-8
y=-2
in (x,y) form
(-8,-2)
In my personal opinion I'd say a gallon, just because when someone asks "How much lemonade is in that pitcher?" I think it's best to say a gallon over 16 cups(:
Area=pi times radius^2
area=36pi
36pi=pi times radius^2
divide both sides by pi
36=radius^2
square root both sides
6=radius
2radius=diameter
2 times 6=12
radius=6
diamater=12
the answers area A and D
(if you know your radius and diameter, you would know that diameter is 2 times radius and you could eliminate 2 choices imedietly (B and C))
Answer:
Answer: The truck is worth of $27508 after 2 years.
Step-by-step explanation:
Since we have given that
The value in dollars v(x), of a certain truck after x years is represented by the equation :
We need to find the price of the truck after 2 years,
so, x= 2
So, we put the value of x = 2 in the above equation:
Hence, the truck is worth of $27508 after 2 years.
