Answer and Step-by-step explanation:
Although the question is not complete, but with the context of the question, they are most likely going to ask for the total distance travelled or the total time or speed. So let's work on that.
Total time travelled = (3 + 5 + 4) = 12mins
Total speed travelled = (0.50 + 0.00 + 0.40)miles/min = 0.90mile/min
The 0.00 represents the period he was at rest admiring an antique car. At this moment, he was not moving so his speed is 0.
Total distance travelled = total speed x total time = 0.90miles/min x 12min = 10.8miles
Answer:
-x³ + 5y + 3
Step-by-step explanation:
It helps to rewrite the given polynomial according to its degree (exponent), in <u>descending</u> order. Also, for variables without a coefficient, it helps to include "1" with it to make it less confusing when combining like terms.
- x³ + 3y + ( 1 )y + ( 1 )y + 5 + 2 - 4
One way to simplify a polynomial is to combine the like terms if there are any. Two or more terms in a polynomial are like terms if they have the same variable(s) with the same exponent.
- x³ is the only term with an exponent of 3, so we wouldn't have to combine it with other terms. We need to combine the terms with the variable "y," as they have the same degree of 1.
- x³ + 5y + 5 + 2 - 4
Lastly, combine the constants (5 + 2 - 4):
- x³ + 5y + 3

Please, Moody, use " ^ " to denote exponentiation:
f(x) = x^3 and g(x) = <span>(x – 1)^3 + 2
Once you have drawn the graph of f(x) = x^3, you get the graph of g(x) by translating the entire graph of f(x) one unit to the right and then translating the result graph 2 units UP.</span>
FOIL is an 'acronym'. It helps you remember how to multiply
two binomials ... like (2x-7) and (5x+5) .
FOIL stands for "First, Outside, Inside, Last". Here's how it's used
to multiply these particular two binomials:
(2x - 7) (5x + 5)
First: (2x) (5x) = 10x²
Outside: (2x) (5) = 10x
Inside: (-7) (5x) = -35x
Last: (-7) (5) = -35
Add them all together, and you have the product:
10x² + 10x -35x -35
Simplify the sum: 10x² - 25x -35
or 5(x² - 5x - 7) .
