Answer:
4x - 5 > 7 = [3,∞)
Step-by-step explanation:
Move all terms not containing x to the right side of the inequality.
4x<u> > </u>12
Divide each term by 4 and simplify.
x <u>> </u>3
Convert the inequality to interval notation.
[3,∞)
I hope this helps
if you could, feel free to mark me Brainliest it would be much appreciated :D
Given that the number of bridges has been modeled by the function:
<span>y=149(x+1.5)^2+489,505
To find the year in which, y=505000 we shall proceed as follows:
From:
</span>y=149(x+1.5)^2+489,505
substituting y=505000 we shall have:
505000=149(x+1.5)^2+489,505
simplifying the above we get:
0=149(x+1.5)^2-15495
expanding the above we get:
0=149x^2+447x+335.25-15495
simplifying
0=149x^2+447x-15159.8
solving the quadratic equation by quadratic formula we get:
x~8.69771 or x~-11.6977
hence we take positve number:
x~8.69771~8.7 years~9 years
thus the year in which the number will be 505000 will be:
2000+9=2009
Simple...
