We can use the formula y2-y1/x2-x1 to find slope given two points. Therefore, we have -1-8/-2-1, getting us -9/-3, or just 3. Hope this helps!
Answer:
4.94x10^13
Step-by-step explanation:
You have to move the decimal 13 times to the right and the number you get or it to be in scientific notation has to be in between 1 and something less than 10.
You probably don't need this answer anymore, sorry!
Answer:
x = 23
Step-by-step explanation:
Isolate x.
x - 15 = 8
x = 15 + 8
x = 23
X^2-16 is a difference of squares of the form:
(a^2-b^2) which always factors to:
(a+b)(a-b), in this case we have:
(x+4)(x-4), we are told that width is (x+4) so the length is:
(x-4)
Answer:
Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455
x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills
Check:
OK.
