Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.

Elena's car: 7000 + 21000t

Marc's car: 20000 + 11000t

To find at what time t they are equal, set these two expressions equal to each other and solve for t.

7000 + 21000t = 20000 + 11000t

13000 = 10000t

t = 1.3 years from now

The graph below is a portion of a complete graph. Which graph below is the complete graph assuming it is an even function?
Ierofanga [76]

Answer:

Option b

Step-by-step explanation:

A function is even if and only if f(-x) = f(x).

This means that there is the same value of y for x_0 and for -x_0

Where x_0 is any point belonging to the function .

Therefore you must select a graph whose ordered pairs are of the form (x_0, y_0) and (-x_0, y_0)

Therefore the correct answer is option b. Assume that each box in the graph equals 1 unit. Then, for x = 2 y = -3 and for x = -2 y = -3. Then it is shown that the function is even.

when you subtract one negative integer from another will your answer be greater than or less than integer you started with? Expl
pshichka [43]
Lets take   (-4) - (-6) 
             = -4 + 6     (here we changed the sign because in integers when you are                                                     subtracting <span>an integer, we put its opposite..thats the rule .)
            =. -4 + 6 = 2

so here we got the answer as 2 .....this shows that </span>your answer will be less than the integer you started with ....this is because here in subtraction we will first change the sign and then follow the same rules of addition ...so here if both the numbers have opposite signs then we subtract and put the greater number sign .....
<span>
Hope i am right !!!</span>
