You can't simplify 2/3, but you can divide both sides of 6/10 by 2 to simplify it. 6/10=3/5, which doesn't equal 2/3.

2/3 is not equivalent to 6/10
thats because 3 times 3 doesnt equal to 10. it equals to 9.
so 2/3 equals to 6/9
hope it helped

Am I correct? Please show your work so I can compare it to my work. Thank you!
Viefleur [7K]

Answer:

200

Step-by-step explanation:

C = 0.007x² − 2.8x + 100

There are two ways we can find the minimum.  The first is by noticing that this is an upwards parabola, so the minimum is at the vertex.  For y = ax² + bx + c, the vertex is at x = -b/(2a).

x = -(-2.8) / (2 × 0.007)

x = 200

Alternatively, we can minimize C using calculus.  Take the derivative with respect to x and set to 0:

dC/dt = 0.014x − 2.8

0 = 0.014x −  2.8

x = 200

Determine the direction that this parabola opens y=4x^2+8x+2
just olya [345]
For this case we have a quadratic equation of the form:
 ax ^ 2 + bx + c

 What we must keep in mind to know which direction opens the parabola, is the value of a.
 We have two options:
 If a <0 the parabola opens down
 If a> 0 the parabola opens up
 We have the following equation:
 y = 4x ^ 2 + 8x + 2&#10;
 We observed that:
 a = 4 (a\ \textgreater \  0)&#10;
 Therefore, the parable opens up.
 Answer:
 
the direction that this parabola opens is:
 
Upwards
