Answer:
2.85
Step-by-step explanation:
2x+20=25.7
2x+20-20=25.7-20
2x=5.7
2x/2=5.7/2
x=2.85
4/ 3 log2
X= 4.4292 enter in calculator
Yes the one u choosing(C) is right
We let x be the initial amount of money and r be the rate of interest (already in decimal) such that the equation for the future worth of money is,
after two years, F = 44100 = x(1 + r)^2
after four years, F = 48620.25 = x(1 + r)^4
Solving for the values of x and r in the equation will give us answers of 40,000 and 0.05, respectively. Thus, the interest rate is approximately 5%.
Y=3x+6
slope is
![\frac{3}{1} x](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B1%7D%20x)
which can just be written as 3x
And your y intercept is the point where x=0, in this case when y=6, x=0. so you write slope(x)+/- your y intercept
