3 - 13x - 7x^2 - (5x^2 + 12x - 10)
Distributing the negative over the parentheses chamges the signs:-
= 3 - 13x - 7x^2 - 5x^2 - 12x + 10
adding like terms:-
= -12x^2 - 25x + 13 (answer).
Its B
Answer:
a
Step-by-step explanation:
Total Distance = 6.45km + 150m + 500m
Convert meters to kilometers:
Total Distance = 6.45km + 0.15km + 0.5km
Add them up:
Total Distance = 7.1km
Find total distance he rode in 3 days:
1 day = 7.1 km
3 days = 7.1 x 3 = 21.3 km
-----------------------------------------------------------------------------------
Answer: He rode 21.3 km in the 3 days.

To find slope you want to do the rise over the run. First you identify your coordinates which in this case are (0,0) and (2,1). Then you do the rise over the run or in a fraction out the number of how many units you go up (rise) and how many units you go accross (run). So for this slope you would put your rise of 1 over your run of 2 and your answer would be s=1/2 (s stands for slope)
Answer:
C
Step-by-step explanation:
f(x)=0 at points of intersection of the graph of the function with x-axis.
From the diagram you can see that the graph of the function intersects x-axis at three points:
somewhere between -3 and -2;
somewhere between -1 and 0;
at x=1.
Since x=1 is the value of x from the domain, then correct choice is option C.
