Answer:
5 hours
Step-by-step explanation:
if they hike 3 miles per 1 hour, and you divide 15 (miles) by 3 (miles) you get 5 hours because each hour they walk 3 miles
(so sorry if this is confusing!! its very hard to explain for me lol)
If you put it into the slope intercept from (x1,y1) and (x2,y2)
then subtract 3-8 and 2-5 you should get 5\3 as your answer.
the formula is a_{1}+(n-1) d
so a_{1} would be the first number in the sequence, which would be 13 in problem 9.
13+(n-1)d
then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)
13+(10-1)d
then you find the difference between each number, represented by d which in this case is 3
13+(10-1)3
13+(9)3
13+27=
40
Answer:
Step-by-step explanation:
hello :
(x-4)²(x+3)² = -1
means : ((x-4)(x+3))² = - 1 this equation has no solutions in R
because for all x in R : ((x-4)(x+3))² ≥ 0
For this case we have the variable :
Now, matching each expression with its value we have:
A goes with 4
B goes with 3
C goes with 2
D goes with 1
ANswer:
A goes with 4
B goes with 3
C goes with 2
D goes with 1
