A graph of the equation shows the appropriate choice to be
C. 2_____
If you would rather, you can look at the value of the discriminant. For the equation y = ax²+bx+c, the discriminant (d) is
d = b²-4ac
For your equation, this evaluates to
d = (-8)²-4(2)(5) = 64 -40 =
24When the discriminant is
positive, the function has
two real roots (2 x-intercepts). When it is zero, there is only one x-intercept, and when it is negative, there are none (the roots are complex).
2/ 3 - (3 - 1) * 3 - 1 = -4
Simplify
= 2/-4
which is
= -2/4
Then simplify again
= -1/2
500 total magazines...
Amy sold 1/9......1/9(500) = 500/9 = 55.5
Garret sold 0.145.....0.145(500) = 72.5
Robbie sold 12/100.....0.12(500) = 60
Carlita sold 0.095.....0.095(500) = 47.5
Garret sold the most
or u could have done it this way...
Amy sold 1/9.....1/9 = 11.1%
Garret sold 0.145 = 14.5%
Robbie sold 12/100.....12/100 = 12%
Carlita sold 0.095....0.095 = 9.5%
u will still get the same answer...Garret
Answer:
x < .6
Step-by-step explanation:
1+5x<4
Subtract 1 from each side
1-1+5x<4-1
5x<3
Divide each side by 5
5x/5 <3/5
x < .6
The 4 functions are:




Let's keep in mind that for large values of x, a quadratic function grows faster than a linear function:

for large values of x
In this problem, we can see that the only quadratic function is

, while all the others are linear functions, so the function that grows faster for large values of x is
