Answer:
Solutions are (3,1) and (4,2)
Step-by-step explanation:
Graph is shown in the attached sheet
Given are two systems of equations and we have to solve them using graph
For graphing let us first prepare table for x and y.
1)
I line II line
x 0 4.5 3 x 0 2.5 3
y 3 0 1 y -5 0 1
The two lines intersect at (3,1)
Hence solution is (3,1)
--------------------------------------------
2)
I line II line
x 0 2 4 x 0 6 4
y 0 1 2 y 3 0 2
The two lines intersect at (4,2)
Hence solution is (4,2)
Answer:
32.63 F
Step-by-step explanation:
The function:
represents sound travels s at feet per second, where t is the temperature at Fahrenheit degrees.
We know that sound traveled at a rate of 1121 ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.
