Answer:

Yes, his calculation is reasonable. He will have about $16.67 left.

Step-by-step explanation:

200 - (200 * .2) = $160 <em>Subtract money for savings</em>

99.95 + (99.95 * .07) + (17*2) + (17 * .07) + (17 * .07) = $143.33 <em>Add taxes</em>

160 - 143.33 = $16.67 <em>Subtract money for purchases from money left after savings</em>

What do all members of the family of linear functions f(x)=1m(x+3) have in common?
dsp73
All linear functions have in common...
1. Their highest exponent is 1.
2. The graphs of the equations are lines.

When finding things in common between different types of functions, you always have to look at the two sides of math; geometry and algebra. Geometry is all the graphs, and algebra is the equations.

I hope this helps!

What is the area of this shape? I got 1800 square foot. PLEASE HELP!!!!! How did you get the answer also?
Delvig [45]
For this question first you should find the area of the triangle so you should say:
3*6/2 = 18/2 = 9 ft
now you should find the area of the rectangular so you should say:
16*8 = 128 ft 
now you should add them together so you will have:
128 + 9 = 137 square foot :)))
i hope this is helpful
