what is bigger 5.62 or 5.5
Answers
Answer:
5.62
Step-by-step explanation:
5.62 is bigger than 5.5
5.62 is bigger by 0.12
You can prove this by subtracting 5.5 from 5.62
If you were to subtract 5.62 from 5.5 you'd end up with a negative number, so obviously 5.62 is bigger

a. (g*f)(3)
b. (f*g)(x)
Answers
Answer:
b. (f*g)(x)
Step-by-step explanation:
Set up the composite result function.
g ( f ( x ) )
Evaluate
g (f ( x ) )
by substituting in the value of
f into g . g ( 2 x 2 + 3 ) =3 ( 2 x 2 + 3 ) − 2
Simplify each term.
g ( 2 x 2 + 3 ) = 6 x 2 +9 − 2
Subtract
2 from 9 . g ( 2 x 2 + 3 ) = 6 x2+ 7

A TV has an original price of $499. Find the new price given a 10% increase.
Answers
Have a great day/night
Answer: $548.9
Step-by-step explanation:
To find the next price you have to find 10% of the original price then add it. You can find the increase by dividing 499 by 10 to get 10%.
499 divided by 10 = 49.9
Now add the increase to the original price for your answer!
499 + 49.9 = $548.9

Katelyn has $1200.45 in her checking account. She spent $85.70 on groceries, paid her rent of $1000. Her grandmother sent her a check for her birthday for $85. How much money will be in Katelyn's account at the end of the month?
Answers
Answer:
$199.75
Step-by-step explanation:
Total money she has be x,
→ x = 1200.45 + 85
→ [ x = $1285.45 ]
Katelyn totally spend be y,
→ y = 85.70 + 1000
→ [ y = $1085.70 ]
Money left in Katelyn's account at the end of the month,
→ x - y
→ 1285.45 - 1085.70
→ $199.75
Hence, the money left is $199.75.

Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.
I need to find an equation, a table, and a graph
Answers
Answer:
earnings = $125 + ($50/vacuum)x
Step-by-step explanation:
This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:
The equation represents the man's total earnings. The independent variable is x, the number of vacuums he sells.
Thus, earnings = $125 + ($50/vacuum)x. As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).
Plot a black dot at (0, $125). Now move 2 units to the right from this dot and from there up by $100 to (2, $225). Plot this new point. Then draw a line through the two points you've plotted.
Table:
x earnings
---- --------------
0 $125
1 $125 + $50 = $175
2 $125 + $100 = $225
and so on.
