Answer:
(f-g)(x) = -x^2 - 2x +2.
Step-by-step explanation:
(f-g)(x)=f(x) - g(x)= (x-2)-(x^2+3x-4)
= x-2 -x^2 -3x +4
= -x^2 - 2x +2.
Then , the answer is (f-g)(x)= -x^2 - 2x +2.
Hope that you understand.
She can buy 5 songs and still have 7 dollars left
5 + 2 = 7
7 x 5 = 35
Less than 40
7 x 6 = 42
But this is too much
So it would be 5 songs he could buy and still have $7 left. ( 7 x 5 = 35 )
$50,400
Multiply $2,000 by 0.05 (because that's 5% converted to decimal) and you should get $100. Add that to $2,000 (which is $2,100) and multiply it by 4 because you're depositing 4 times a year. You should then get $8,400 and multiply it by 6 and you get your answer
Initial length = 72 cm
Stretched length = 90 cm
Find the increased in length:
increase = 90 - 72 = 18
Find the percentage increase:
Percentage increase = change/original x 100
Percentage increase = 18/72 x 100 = 25%
Answer: The elastic band's length is increased by 25%
$15 + $32.50 + 8% = $51.30
15 + 32.50 = 47.50
8% × 47.50 = 3.80
47.50 + 3.80 = 51.30
