You can just set y=0 and solve for x. when you do this you should get 1/2x^2=4
x^2=8
x=2.8 and -2.8 ( you have both a positive number and negative number since (-2.8)^2=(2.8)^2 =8
I hope this helps
1, 10, 25, 50, and so on...
Mark brainliest pls :)
a.
38<14+0.05x
24<0.05x
x>480
b. When the number of calls per month is greater than 480, then Plan 1 is more economical. Example: If the number of calls is greater than 480 say 500, then charges in plan 2 will be $39, but Plan 1 is more economical and charges will be $38.
First convert 5,280 ft. into inches.
5280 ft. equals 63360 inches.
Then you divide that by 42
If you're rounding to the nearest step then it would take 1509 steps to run 1 mile.
We can't see the whole question :/
