subtrace x from y means y-x so
subtract 3x^2-7x+4 from 5x^2-3x+8 means
5x^2-3x+8-(3x^2-7x+4)=
5x^2-3x+8-1(3x^2-7x+4)
5x^2-3x+8-3x^2+7x-4=

On a vacation to Puerto Rico Rose jumped off a cliff into a river in Elion forest preserve her height as a function of time to be modeled by the function HFT equal 16 T squared +16 T +480 where T is the time after jumping in seconds and H is the height in feet how many seconds it take Rose to hit the water round your answer to the nearest hundredth

Answers

To solve for t, you will use the equation given: -16t^2 + 16t + 480 = 0. First, simplify the equation by dividing everything by 16: -t^2 + t + 30 = 0. Then complete reverse FOIL: (-t + 6)(t + 5) = 0. Next, set each of these equations to 0 separately, and solve for t. You will get t = 6, and t = -5. Since time can't be negative (Rose can't have hit the water after a negative number of seconds), the answer is 6.

HELP PLEASEEEE!!The math team decided to sell customized pocket protectors as a

How long a line can you make using all the 3/8 inch strips

Answers

The length of the line calculated by using 3 / 8-inch strip will be ( 3/8 )x

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The total amount of line that the line will have depends on the number of strips, and the result is equal to the multiplication of the number of strips, x, and the length of the strips by 3/8 inch

Total length = ( 3/8 )x

where x is the number of strips, and the total length is in inches

Therefore the length of the line calculated by using 3 / 8-inch strip will be ( 3/8 )x.
