What is the value of 2x^4 5x when x=6(please show work thank you)!

1 answer:

3 0

So when you plug in x, you get 2(6^4)*5(6). So simplifying the equation, we get 2(36^2)(30). Getting the square of 36, 2(1296)(30) so we can change it to 60(1296) which is 77,760

How many solutions do these equations have

Arlecino [84]

Answer:

$\large\boxed{\bold{one\ solution}\ (1,\ -4)\to x=1,\ y=-4}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}y=2x-6\\y=-x-3\end{array}\right\\\\\text{These are linear functions. We only need two points to draw a graph.}\\\\\text{Choice two values of x, substitute to the equation,}\\\text{and calculate the values of y.}\\\\y=2x-6\\for\ x=0\to y=2(0)-6=0-6=-6\to(0,\ -6)\\for\ x=3\to y=2(3)-6=6-6=0\to(3,\ 0)\\\\y=-x-3\\for\ x=0\to y=-0-3=0-3=-3\to(0,\ -3)\\for\ x=-3\to y=-(-3)-3=3-3=0\to(-3,\ 0)\\\\\text{Look at the picture}$

$\text{The intersection of the line is the solution of the system of equations:}\\\\(1,\ -4)\to x=1,\ y=-4$

There are 18 cans of peas in a case. Each can of peas is 12 ounces. If a case of peas costs $14.22, what is the unit price per c

Elan Coil [88]

Okay doll so this is how you do it.

The 12 ounces doesn't matter. Its irrelevant.

You divide 14.22 by 18.

And that's all there is to it.

The answer is C. $0.79
