Answer:

x=1.75

Step-by-step explanation:

First add 5 to each side then you would have 4x+7=8x then subtract 4x from each side and you'll get 7=4x the divide each side by four and you'll get 1.75=x

The volume of a cubical box is 474.552m3.Find the length of each side of the box
Cerrena [4.2K]

The formula of a volume of a cube:

V=a^3

We have V=474.552\ m^3

Substitute:

a^3=474.552\to a=\sqrt[3]{474.552}\\\\a=7.8\ m

Answer: The length of each side of the box is equal 7.8 m.

How many solutions does this linear system have?
ziro4ka [17]

Answer: C is correct, No solution

Step-by-step explanation:

Let’s simplify the second equation,

8x-4y=-20

We can divide the whole equation by 4...

8x/4-4y/4=-20/4

Which becomes....

2x-y=-5

Now let’s move things around to see if it’s the same equation as the one on top...

-y=-2x-5

y=2x+5

Now we need to solve the systems...

y=2x-5

y=2x+5

Since their slopes are both 2 and their y-intercepts are not identical, the answer is no solution. The two lines will continue on without ever crossing because they have the same slope.

Identify which of the twelve basic functions listed below fit the description given. 1 ,y1+e y=x,y=xy=*',y = lxl.y = y=e"y= V,y
skelet666 [1.2K]

remember that local minimuns are points in which the function was decreasing and starts increasing.

you can try two ways of doing it, graphing the functions or using derivatives.

since this are twelve functios the easier way is to graph them.

start by function y=x

in this case this function is continously increasing as x increases, which means that it does not have any local maxima or minima.

now do the same for

y=x^2

this graph has a local minima on th
