For this case, we have that by definition, be given two functions f (x) and g (x). So:
We have:
So:
(f-g) (x) = - 3x-5- (4x-2)
We have to:
Equal signs are added and the same sign is placed while different signs are subtracted and the sign of the greater is placed
Answer:
Option D
Answer:29
Step-by-step explanation: the answer is 29 because if there are three consecutive numbers, we know that the second and third number must be one and two units larger respectively. As such you can subtract the difference from the combined number (1 (2nd number) + 2 (third number) = 3 --> 90 - 3 = 87). So, if you divide the new number (87) by three (the number of consecutive integers required for this question) the answer is 29. If the answer is 29, we know that the second and third number in the sequence must be 30 and 31. 29 + 30 + 31 = 90.
Answer:
$56.82
Step-by-step explanation:
The sum of all the stuff she bought is 10+20+23, so 53.
Now you need to find the tax, so you multiply 53 x 7.2%, and to change a % to a number you move the decimal place two to the left, so you get .072
$53 x .072 = $3.816 sales tax
$53 for the stuff plus $3.816 tax = $56.816
and since money is only two decimal places and the 6 is higher than 5, you have to round up to the nearest penny, so $56.82!
