X=cost per hamburgurs
y=cost per hot dog
200x+150y=1450
200x+250y=1750
we can multiply first equation by -1 and add to 2nd
-200x-150y=-1450
<u>200x+250y=1750 +</u>
0x+100y=300
100y=300
divide both sides by 100
y=3
sub back
200x+150y=1450
200x+150(3)=1450
200x+450=1450
minus 450 both sides
200x=1000
divide both sides by 200
x=5
the cost of a hamburgur is $5
the cost of a hot dog is $3
Answer:
Exponential decay function; -0.94%
Step-by-step explanation:
We are given an exponential function and we are supposed to find whether the given function increases or decreases and also the percentage of increase or decrease.
Th given function is f(x) = 2060
Here x denotes the number of years.
At the start the value was 2060. In the next year it was multiplied by 0.9906.
This means that the value becomes 0.9906 times after each year.
Hence the value decreases by 0.0094 times its original value.
Converting to percentage it becomes 0.94% decrease after each year.
Answer:
The length of the base of the rectangle is 7 inches
Step-by-step explanation:
The Area of the rectangle can be found out by multiplying length with the breadth
Area= length * breadth
35 squared inches= x *5
5x= 35
x= 35/5
x= 7inches
Hence the length of the base of the rectangle is 7 inches.
If the area and one side are known then we can simply find the 2nd side by simply substituting x in its place and solving the equation.
