√x + 9 - 4 = 1
√x + 5 = 1
√x = -4
√x = √-4
x = 2i
In the equation y=mx+b, the variable m represents the slope of the line. Therefore, the equation -5x+2y=10 can be rearranged into 2y=5x+10. Isolate the y to get y=2.5x+5. The slope of the line is 2.5
9w+45= amount of money she’ll have after any amount of weeks.
So, since W is weeks... and you have 9 weeks, you do (9x9)+45.
Then you get 81+45, which is 126. She will have $126 after 9 weeks
Cross multiply:
2.5 ft x 16.5 ft = 41.25 ft
now divide:
41.25 / 8.25 = 5
L = 5 feet
