It looks as though there are 25 21-40 year-olds. 40% of 25 is 10, this is the amount that are AGAINST the increase. Therefore the ones in favor for the increase must be 25 - 10 = 15.
You should be able to follow the same process to get the 41-60 year-olds against an increase. Just be sure to read the given information carefully
Answer:
To find x intercept, u graph it
the x intercept is 1.67
Step-by-step explanation:
Answer:
-2.65
Step-by-step explanation:
-1.2 - 1.45 = -2.65
you could just simplify fraction into decimal and use calculator
I hope this helps you
2 (x+x+x+x+x+24+24)=120
4x+48=60
x=3
Area =2x.24
Area =2.3.24
Area =144
so we have the points of (0,-7),(7,-14),(-3,-19), let's plug those in the y = ax² + bx + c form, since we have three points, we'll plug each one once, thus a system of three variables, and then we'll solve it by substitution.

well, from the 1st equation, we know what "c" is already, so let's just plug that in the 2nd equation and solve for "b".

well, now let's plug that "b" into our 3rd equation and solve for "a".
