Answer: B. 130% increase
Step-by-step explanation:
Given function : 
If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.
This function is equivalent to the exponential growth function
, where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]
Thus,
Hence, the annual percent increase is 130%.
20 shares at 10 1/2 (or 10.5) = 20 * 10.5 = 210
20 shares at 11 1/4 (or 11.25) = 20 * 11.25 = 225
so the profit made would be : 225 - 210 = $ 15 <==
Answer: = 0.198
Step-by-step explanation:
0.60 * (100% + 33%) = 0.60 * 133% = 0.60 * 1.33 = 0.798
The markup is 0.798 - 0.60 = 0.198, which is also 0.60 * 33% = 0.60 * .33 = 0.198
0.3x ≥ 0.6
Divide both sides by 0.3,
0.3x / 0.3 ≥ 0.6/0.3
x ≥ 2
So, your final answer is x ≥ 2
Hope this helps!
If x is the age and y is the diameter of the trunk, write the equation:
ax+b=y
We must solve for a and b with the given information.
If (x, y) is (1, 4), we have:
a+b=4
If (x, y) is (10, 25), we have:
10a+b=25
Multiply the first equation by 10 to get:
10a+10b=40
Subtract the second equation from this to get:
9b=25
Thus b=25/9. a=4-25/9=11/9, so our equation is 11x/9+25/9=y.
