Answer:
x ≥-10
Step-by-step explanation:
–2.5x ≤ 25
Divide each side by -2.5, remembering to flip the inequality
–2.5x/-2.5 ≥ 25 /-2.5
x ≥-10
Answer: First, multiply 5 by x-2 to get 5x-10. We now have 5x-10=2x+16. Subtract 2x on both sides: 3x-10=16. Add 10 to both sides: 3x=26. Lastly, divide by 3x to isolate x: x=8.6666667
Y = -3x + 6/7
switch the x and y, then solve for y:
y = -x/3 + 2/7
First, determine the annual effective interest based on the annual interest and the compounding,
ieff = (1 + i/m)^m - 1
Substituting,
ieff = (1 + 0.03/12)^12 - 1 = 0.0304
To determine the future worth (F) of the current investment (P) is,
F = P(1+ieff)^n
Substituting all the known values with n unknown,
3000 = 175(1 + 0.0304)^n
Solving for n gives an n = 94.8867 years
Among the choices, the nearest value is 94.8377 years.
Answer:
Option 1, 2, and 4 are correct. Option 3 is incorrect.
