A function has the function rule y = -7 x - 2. If the input is -4, what is the output? 26 -30 -26 14

GaryK [48]

Answer:

Step-by-step explanation:

Since the input is -4, x = -4. The equation then is y = -7(-4) -2

A negative times a negative is a positive, so -7 times -4 is 28.

Now the equation reads y = 28 - 2

Then obviously you just subtract the two and then you get 26.

amid [387]

Answer:

l = 6 inches

Step-by-step explanation:

We have,

The volume of a rectangular prism with a square base is $180\ in^3$ .

Height of the prism is 5 in

It is required to find the length of the edge of the square base. Let it is l.

The formula of the volume of the rectangular prism is given by :

$V=l\times b\times h$

A is area of base of prism

It has a square base, l =b

$V=l^2\times h\\\\l=\sqrt{\dfrac{V}{h}} \\\\l=\sqrt{\dfrac{180}{5}} \\\\l=6\ in$

So, the length of the edge of the square base is 6 inches.
