Caleb paid $26.70, including a 7% sales tax, for a security wallet. how much did the wallet itself cost?
3* (n+7) = -36
3n+21 = -36
subtract 21 from each side
3n+21-21 = -36-21
3n = -57
divide by 3
3n/3 = -57/3
as we know that if two parallal line cut by a transversal opposide angles are same and corisponging angle are same so < 1 and< 8 are same means< 1=< 8 so we can write 2x+35=10x-85
10x-2x=85+35 8x=120 x=120/8 x=15 ans is d. 15
here x =time logged in and hence cannot be negative
so domain = [0,∞)
where here independent variable is distance the dependent is his jogging time.
even when x=0, f(x) =50
so domain is [50,∞)
here independent variable is daily earnings and dependent variable is her computer sales in dollars
here domain =[0,10] (given)
in the inverse independent variable is distance travelled and dependent is time in seconds.
here independent variable is total money earned and x number of tickets sold
