Answer:
x= 6
Step-by-step explanation:
You need to set up a proportion
12/8 = 9/x
Then you do Cross Product Property
8*9=72
12*x=12x
12x=72
divide 72 by 12
72/12=6
x=6
Answer:
The next 3 numbers to the given pattern of integers is -2,-1,-1,0,-1,1,-2 are 3,-5,8
Step-by-step explanation:
Given pattern of integers is -2,-1,-1,0,-1,1,-2
To find their next 3 numbers of the given pattern :
Let
Therefore
Therefore
Similarly we have , ,
The general form to the given pattern is
for
Therefore to find the
Put n=8 in
Put n=9 in
Put n=10 in
Therefore the next 3 numbers are 3,-5,8
Answer:
x=1.55
Step-by-step explanation:
42x-1=64
+1 +1
42x= 65
/42 /42
x= 1.55 (rounded)
Answer:
40 mL of 10% acid
80 mL of 25% acid
Step-by-step explanation:
x = volume of 10% acid solution
y = volume of 25% acid solution
Total volume is:
x + y = 120
Total amount of acid is:
0.10 x + 0.25 y = 0.20 (120)
Solve by substitution.
0.10 x + 0.25 (120 − x) = 0.20 (120)
0.10 x + 30 − 0.25 x = 24
0.15 x = 6
x = 40
y = 80
You have not provided a function, however, normally when the instructions say to use graphs, you just need to graph it in your calculator and then take a look at it to see what the limit will be at the requested x value. Remember to write your asymptote as a linear equation once you identify it from the graph.
