1 glove costs $48
5 gloves cost $240 (since 5*48 = 240)
1 bat costs $35
b bats cost 35*b dollars, where b is some positive whole number
The total cost of the bats and gloves is 35*b + 240. We simply add the subtotals (240 from the gloves and 35*b from the bats)
Plug in b = 3 and use PEMDAS to evaluate
35*b + 240
35*3 + 240 .... b has been replaced with 3
105 + 240
345
---------------------------------------------------
To summarize:
The cost expression is 35*b + 240 (the cost is in dollars)
The total cost if the coach bought three bats is 345 dollars
If a flight departs from Pittsburgh at 7:55 a.m. and arrives in San Diego at 9:20 a.m.,
How long is the flight?
SOLUTION
9. 20 am - 7. 55 am = 1 hour 25 mins
Vertical means in the y-direction
Stretch by factor of 8 means everything is multiplied by 8
so g(x) = 8 * f(x)
= 8 * (3/4 x^2 -1)
= 8*3/4 x^2 - 8*1
= 6x^2 - 8
Answer:
Value is 15 and measure is 151
