Answer: x < 8/9


Step-by-step explanation:

The equation is 4 * (2x +1) * 4.5 = 50, since the volume is found by multiplying the length, width, and height together, and the =50 part is because our volume can't go above 50 cubic units.


We can simplify 4 * (2x+1) * 4.5 by multiplying 4 and 4.5, which is 18, and then multiplying both 2x and 1 by 18. We get 36x + 18, and we put in the =50, so it is 36x+18=50.

Next, we can subtract 18 from both sides of the equation, giving us 36x = 32.

We then divide the equation by 36 so that we have the x by itself, and we get x = 32/36, which can be simplified to 8/9.


What we're left with is x = 8/9, meaning plugging in 8/9 for the equation would give us 50. However the problem says that the volume must be below 50, so our actual answer is x < 8/9.

Which of the quadratic functions has the widest graph? y = 0.3x2 y = –4x2
Alenkinab [10]
A vertical stretching is the stretching of the graph away from the x-axis.
A vertical compression is the squeezing of the graph towards the x-axis.
A compression is a stretch by a factor less than 1.

For the parent function y = f(x), the vertical stretching or compression of the function is a f(x). 

If | a | < 1 (a fraction between 0 and 1), then the graph is compressed vertically by a factor of a units.
If | a | > 1, then the graph is stretched vertically by a factor of a units.

For values of a that are negative, then the vertical compression or vertical stretching of the graph is followed by a reflection across the x-axis.

Thus, the equation with the widest graph is 0.3x^2.

Step-by-step explanation:

g(f(x)) = f(x) substituted in g(x)'s function.

g(3x^2 - x - 8) = 3x^2 - x - 8 + 5 = 3x^2 - x - 3.

Last week, a chocolate shop sold 2 5/6 ounces of white chocolate. It sold 6 2/3 times as much milk chocolate as white chocolate.
Nookie1986 [14]

Answer:

18.8888888889

Step-by-step explanation:

2 5/6 = 2.83333333333

6 2/3 = 6.66666666667

2 5/6 * 6 2/3 = 2.83333333333 * 6.66666666667

2.83333333333 * 6.66666666667= 18.8888888889
